Abstract:

Pure amine-bis(phenol) ligands are readily accessible in high yield, often >90%, when the Mannich condensation reactions are performed “on water” or in poly(ethyleneglycol) (PEG). Microwave-assisted synthesis dramatically reduces the time and energy required to prepare these molecules, typically from 24 h to 5 min. The approach seems to be widely applicable (7 amines and 5 phenols were tested to yield a diverse set of bis(phenol) ligands). Significant improvements in yield were observed for ligands derived from di-tert-amyl and di-tert-butyl phenols, possibly resulting from a hydrophobic effect. Single crystal X-ray diffraction data for the ligand derived from p-cresol and N,N′-dimethylethylenediamine is reported.Key words: amine-phenol, Mannich condensation, on water, microwave, ligand, high-throughput.

Abstract:

In the title compound, C20H24N2O5, the dihedral angle between the two roughly planar salicylamide fragments [r.m.s. deviations = 0.043 (2) and 0.149 (2) Å] is 25.50 (5)°. The molecular conformation is stabilized by intramolecular O—H...O hydrogen bonds involving phenol –OH groups and amide O atoms. Intermolecular hydroxymethyl–amide O—H...O and amine–hydroxymethyl N—H...O hydrogen bonds form infinite chains along thebaxis. These chains are further interlinked by amine–amide N—H...O and phenol–phenol O—H...O interactions, thus giving layers parallel to (001).

Abstract:

Removal of phenols from waters and wastewaters is an important issue in order to protect public health and environment. In an effort to develop an effective adsorbent for removal of phenol from aqueous solutions, fly ash cenospheres (FACs), the solid wastes generated from a coal-firing power plant, were modified with an amino-terminated organosilicon (γ-aminopropyltriethoxysilane, KH550). Surface properties of the KH550-modified FACs (M-FACs) were characterized by the X-ray diffraction (XRD), the scanning electron microscopy (SEM) and X-ray photoelectron spectra (XPS). The characterized results showed that KH550 was successfully grated on the surface of FACs. The effects of various experimental parameters such as solution pH, adsorbent dose, and temperature upon the phenol adsorption onto M-FACs were evaluated. The results showed solution pH had a major impact on the phenol adsorption onto M-FACs, the optimum phenol removal was observed around pH 7-9. The kinetic studies indicated that the adsorption process was best described by the pseudo-second-order kinetics, suggesting that the mainly phenol adsorption process was predominantly controlled by chemical process. M-FACs presented more than double adsorptive capacity as compared with FACs. The adsorption capacity of the regenerated adsorbents could still be maintained at 83% by the fourth adsorption-desorption cycle.

Abstract:

A new zinc(II) complex of 2-(((2-((2-hydroxyethyl)amino)ethyl)imino)methyl)phenol (L), [Zn(Lz)Br2] (1), is prepared and identified by elemental analysis, FTIR and 1H NMR spectroscopy, and single crystal X-ray diffraction. The X-ray structure analysis of 1 reveals a tetrahedrally coordinated zinc(II) complex containing the NO-donor amino alcoholic Schiff base ligand and two bromo ligands. After complexation, the ligand (L) converts to its zwitterionc form (Lz) of phenol → phenolate; amine → ammonium. In this structure, hydrogen bonds between amine and alcohol units form different types of hydrogen bond motifs, including R21(7), R22(7), R22(10), R44(24), R44(30), R66(38), and R66(44). In addition to the hydrogen bonds in this crystal network, there are π—π stacking interactions between the phenyl ring and the imine group. The ability of the ligand and its isostructural complexes [Zn(Lz)Br2] (1), [Zn(Lz)Cl2] (2), and [Zn(Lz)I2] (3) to interact with ten selected biomacromolecules (BRAF kinase, CatB, DNA gyrase, HDAC7, rHA, RNR, TrxR, TS, Top II, and B-DNA) is investigated by docking studies. The results show that in some cases, the studied compound can interact with proteins and DNA better than doxorubicin. The charge distribution pattern of the ligand and complex 1 is studied by the NBO analysis.

Abstract:

Aromatic nitro compounds were chemoselectively reduced to the corresponding amines using recyclable polymer-supported formate as a hydrogen donor in the presence of low-cost magnesium powder at room temperature. Use of the immobilized hydrogen donor affords the product amine in excellent yield (90–97%) without the need for any chromatographic purification steps. This method was found to be highly facile with selectivity over several other functional groups, such as halogen, alkene, nitrile, carbonyl, ester, amide, methoxy, phenol, and hydroxyl groups.

Abstract:

2,4,6-Trichloro-1,3,5-triazine (TCT) is a privileged core that has the capacity to undergo sequential nucleophilic substitution reactions. Three nucleophiles, namely phenol, thiol and amine, were studied and the preferential order of incorporation on TCT was found to be first phenol, second thiol and third amine. The introduction of phenol was achieved at −20°C. The incorporation of this nucleophile in TCT helped to replace the third ‘Cl’ at 35°C, which is compatible with a biological context. The atomic charges on ‘Cl’ calculated by theoretical approaches were consistent with the experimental findings.

Abstract:

Structures are reported for eight Schiff bases derived from various salicylaldehydes: five are newly synthesized and re-investigations are reported for three previously reported structures, leading, in each case, to some revision of previous conclusions. In (E)-N-(3,4-dimethylisoxazol-5-yl)-4-[(2-hydroxybenzylidene)amino]benzenesulfonamide, C18H17N3O4S, (I), and (E)-4-[(5-bromo-2-hydroxy-3-methoxybenzylidene)amino]-N-(3,4-dimethylisoxazol-5-yl)benzenesulfonamide. C19H18BrN3O5S, (II), the isoxazole rings adopt different orientations relative to the rest of the molecules, despite the additional substituents in (II) being in the aryl ring remote from the isoxazole unit. The molecules of both (E)-4-bromo-2-[(2-hydroxyphenylimino)methyl]-6-methoxyphenol, C14H12BrNO3, (III), and (E)-4-bromo-2-methoxy-6-[(2-methoxyphenylimino)methyl]phenol, C15H14BrNO3, (IV), are both effectively planar; while (III) adopts the phenol–imine constitution, (IV) adopts the keto–amine constitution. (E)-2-Methoxy-6-[(2-methoxyphenylimino)methyl]phenol, C15H15NO3, (V), which was determined previously using powder X-ray data assuming the phenol–imine constitution, has now been refined from single-crystal X-ray data, confirming the phenol–imine constitution. In (E)-3-benzoyl-2-[(5-fluoro-2-hydroxybenzylidene)amino]-4,5,6,7-tetrahydrobenzo[b]thiophene, C22H18FNO2S, (VI), the fused carbocyclic ring exhibits conformational disorder; both disorder components, having populations of 0.705 (4) and 0.295 (4), adopt half-chair conformations. The isostructural (E)-3-benzoyl-2-[(2-hydroxybenzylidene)amino)]-4,5,6,7-tetrahydrobenzo[b]thiophene, C22H19NO2S, (VII), which was originally reported as having a fully ordered structure [Kauret al.(2014).Acta Cryst.E70, o476–o477], has been rerefined using the original data set and found to exhibit the same type of disorder as found in (VI), with disordered populations having occupancies of 0.851 (3) and 0.149 (3). The triclinic polymorph of (E)-[(2-hydroxyphenylimino)methyl]phenol, C13H11NO2, (VIII), which crystallizes withZ′ = 2 in the space groupP-1, has been described variously as occurring as the keto–amine tautomer [Maciejewskaet al.(1999).J. Phys. Org. Chem.12, 875–880] and as the phenol–imine tautomer [Tunçet al.(2009).J. Chem. Crystallogr.39, 672–676]. Rerefinement of this structure using one of the original data sets shows that both of the independent molecules exist in the keto–amine form. In the structures of compounds (I), (VI), (VII) and (VIII), hydrogen bonds generate simple chains, while a chain of rings is formed in (V). Sheets are formed by hydrogen bonds in both (II) and (III), while in (IV), the sheet structure is built from aromatic π–π stacking interactions.

Abstract:

Synthesis of a polymer with benzoxazine units in the main chain backbone by a trifunctional phenol, a difunctional amine, and paraformaldehyde was achieved. Thermal, mechanical and spectroscopic characterization and the viscosity properties of the synthesized polymer were studied. In the first step of this study, a fast and feasible method for the synthesis of the benzoxazine precursors was developed since some methods mentioned in the literature about the synthesis of the benzoxazine derivatives last long time. The second step was to polymerize the benzoxazine precursors thermally. The curing of benzoxazine precursors was done via ring opening polymerization at 150 oC and a final polymerization was observed at about 250 oC. 1H NMR, 13C NMR and FT-IR spectroscopies revealed the characteristic peaks for the formation of benzoxazine ring. Among them, 13C NMR gave important clue on the formation of the benzoxazine. The thermal characterization of the benzoxazine precursors and the polymers indicated that the ring opening polymerization of these precursors started at around 110 oC and a final polymerization was about at 230 oC. Differential Scanning Calorimetry thermograms of the polybenzoxazine indicated a secondary transition at around 270 oC. An onset decomposition of the benzoxazine oligomers started around 100 oC in Thermal Gravimetric Analysis thermograms performed under N2 atmosphere and two major maximum weight losses were observed at 273 oC and 439 oC. However, polybenzoxazine showed a starting degradation at about 260 oC and the maximum weight loss temperatures were seen at 296 oC and 465 oC. Viscosity variation of the reaction mixture was studied by Ubbelohde Viscometer at 30 oC. Viscosity results indicated that the increase in the intrinsic viscosity of the reaction mixture till 50th minute and followed by a decrease due to possible branching and the intra-crosslinking of the benzoxazine oligomers. Mechanical properties of the polymer films, prepared by compression molding at 180 0C, were investigated. Test results showed that low tensile strength whereas comparatively high elongation.

Abstract:

The detection and potential treatment of oxidative stress in biological systems has been explored using isoindoline-based nitroxide radicals. A novel tetraethyl-fluorescein nitroxide was synthesised for its use as a profluorescent probe for redox processes in biological systems. This tetraethyl system, as well as a tetramethyl-fluorescein nitroxide, were shown to be sensitive and selective probes for superoxide in vitro. The redox environment of cellular systems was also explored using the tetramethylfluorescein species based on its reduction to the hydroxylamine. Flow cytometry was employed to assess the extent of nitroxide reduction, reflecting the overall cellular redox environment. Treatment of normal fibroblasts with rotenone and 2-deoxyglucose resulted in an oxidising cellular environment as shown by the lack of reduction of the fluorescein-nitroxide system. Assessment of the tetraethyl-fluorescein nitroxide system in the same way demonstrated its enhanced resistance to reduction and offers the potential to detect and image biologically relevant reactive oxygen species directly. Importantly, these profluorescent nitroxide compounds were shown to be more effective than the more widely used and commercially available probes for reactive oxygen species such as 2’,7’-dichlorodihydrofluorescein diacetate. Fluorescence imaging of the tetramethyl-fluorescein nitroxide and a number of other rhodamine-nitroxide derivatives was undertaken, revealing the differential cellular localisation of these systems and thus their potential for the detection of redox changes in specific cellular compartments. As well as developing novel methods for the detection of oxidative stress, a number of novel isoindoline nitroxides were synthesised for their potential application as small-molecule antioxidants. These compounds incorporated known pharmacophores into the isoindoline-nitroxide structure in an attempt to increase their efficacy in biological systems. A primary and a secondary amine nitroxide were synthesised which incorporated the phenethylamine backbone of the sympathomimetic amine class of drugs. Initial assessment of the novel primary amine derivative indicated a protective effect comparable to that of 5-carboxy-1,1,3,3- tetramethylisoindolin-2-yloxyl. Methoxy-substituted nitroxides were also synthesised as potential antioxidants for their structural similarity to some amphetamine type stimulants. A copper-catalysed methodology provided access to both the mono- and di-substituted methoxy-nitroxides. Deprotection of the ethers in these compounds using boron tribromide successfully produced a phenolnitroxide, however the catechol moiety in the disubstituted derivative appeared to undergo reaction with the nitroxide to produce quinone-like degradation products. A novel fluoran-nitroxide was also synthesised from the methoxy-substituted nitroxide, providing a pH-sensitive spin probe. An amino-acid precursor containing a nitroxide moiety was also synthesised for its application as a dual-action antioxidant. N-Acetyl protection of the nitroxide radical was necessary prior to the Erlenmeyer reaction with N-acetyl glycine. Hydrolysis and reduction of the azlactone intermediate produced a novel amino acid precursor with significant potential as an effective antioxidant.

Abstract:

Afin de comprendre le mécanisme d'action des inhibiteurs d'oxydation radicalaire, on a entrepris une étude cinétique détaillée de l'oxydation induite, vers 80**(O)C, en phase liquide, du linolénate de méthyle et de son inhibition par des dérivés phénoliques ou par des molécules d'intérêt biologique comme la vitamine E (alpha-tocophérol) ou la vitamine C (acide ascorbique). On montre que deux types de substances : la vitamine C, d'une part, et des molécules aminées comme le glutathion, d'autre part, exercent un effet de synergie sur les propriétés inhibitrices de la vitamine E lors de l'oxydation induite du linolénate de méthyle. L'interprétation de ces phénomènes de synergie a été rendue possible grâce à une étude cinétique de l'oxydation induite des vitamines E et C seules ou en mélange, à une étude cinétique de l'oxydation induite du mélange vitamine E-glutathion et enfin grâce à une étude par RPE et par spectrophotométrie à écoulement bloqué des radicaux libres alpha -tocophéroxyl et ascorbyl. Enfin, on montre que les deux modes de synergie observés se conjuguent pour conduire à une inhibition extrêmement importante de la consommation d'oxygène. Ce résultat est d'un grand intérêt puisqu'il montre que l'on peut presque à volonté protéger de l'oxydation le linolénate de méthyle ou tout autre substrat polyinsaturé

Abstract:

Since, the bio-availability of iron is low in nature, many enteric bacteria use the siderphore enterobactin to sequester ferric iron. Enterobactin is the strongest known binder of ferric iron with a binding constant of K a=1049. The triserine lactone backbone of enterobactin has been credited with being an important factor in the high binding constant. The backbone has been previously used in anion binding studies and as an continuation of that work, phenyl amide enterobactin analogs have been synthesized, characterized and used in 1H NMR titration studies with various halides to determine their binding constants. The phenyl amide enterobactin analogs were found to have binding constants that ranged from approximately 150-7000 L mol-1. The binding constant depended on the analog and halide used. The general trend of Cl- > Br- > I - was seen with all receptors.

Abstract:

Kinetic studies are reported of the reactions of 1,3,5-trinitrobenzene with aniline in dimethyl sulfoxide (DMSO). In the presence of buffers containing 1,4- diazabicyclo(2.2.2)octane, (Dabco), and its acid salt, DabcoH(^+), the anilide σ-adduct is formed. The reaction of ethyl 2,4,6-trinitrophenyI ether with aniline in DMSO containing Dabco occurs in two stages. The first gives σ-adduct intermediate on the substitution pathway, which has been identified spectroscopically. The second yields 2,4,6-trinitrodiphenyIamine, the substitution product. Kinetic studies show that proton transfer is rate-limiting both in the formation of the intermediate and in its subsequent acid-catalysed decomposition. Phenoxide is a considerably better leaving group than ethoxide and the substitution reactions of phenyl 2,4,6- trinitrophenyl ethers and phenyl 2,4-dinitronaphthyI ether with aniline in DMSO occur without the accumulation of intermediates. The kinetics indicate both uncatalysed and base catalysed pathways. Values have been determined for the pK(_a) in DMSO of several ammonium ions derived from amines which have previously been widely used as nucleophiles in nucleophilic aromatic substitution reactions; values are also given for four polynitrodiphenylamines used as indicators. Second order rate constants (K(_s)) are presented for the reaction of substituted phenyl 2,4,6-trinitrophenyl ethers with a series of phenolate ions having pK(_a) values both higher and lower than that of the respective leaving groups in aqueous solution. The rate constants for the reverse reaction (k(_-s)) have also been measured. The Brømsted diagram formed when plotting log k(_s) versus pK(_a) shows a change in slope when ΔpK(_a) = 0 (ΔpK(_a) being the difference in pK(_a) values of the leaving group and nucleophile). This is consistent with a two step process involving a discrete σ-adduct intermediate. From the measured β values effective charges have been determined and the overall effective charge map constructed. Kinetic studies have been made for the reactions of substituted phenyl 2,4,6- trinitrophenyl ethers with substituted phenolate ions in 74% DMSO-water (v/v). Two reactions are observed. The evidence suggests that the more rapid involves formation of a 1,1 σ-adduct between the substrate and the phenolate ions. The slower reaction is attributed to hydroxide attack at the 3-position of the substrate.

Abstract:

AbstractTo meet the demand for shore-based engineering, engineering rescue and traffic emergency support in different complex conditions, a new low-temperature fast solidifier for epoxy resin was synthesized by Mannich reaction using thiourea, polyamine, formaldehyde, phenol and benzyl alcohol. The performance of the curing agent was investigated based on raw material ratio, reaction temperature and reaction time. Moreover, the curing time, amine value, viscosity and infrared spectrum were tested. It was compounded with other highly active curing agents and resins. The compressive strength of the cured sea sand was used as the index to determine the formula of a new epoxy composite used for the rapid curing of sand under low temperature or saturated water conditions. The results showed that the optimal synthesis conditions of the curing agent were as follows: the molar ratio of thiourea, diethylenetriamine, formaldehyde, phenol and benzyl alcohol is 1.2: 1.3: 1: 0.4: 1. The addition of a small amount of accelerator DMP-30 could effectively improve the curing reaction speed and reduce the curing time. These epoxy composites could effectively solidify the sea sand and improve its mechanical properties, which provides important utilization value for coastal engineering construction in the cold season or wet rainy season.

Abstract:

Abstract Bis-Phenol A epoxy resin-based coatings are known for excellent corrosion and chemical resistance. Limitations of this class of coatings are poor flexibility, thermal stability and weather resistance. Traditional siloxane resins are commonly used in the industry to improve the thermal and weather resistance of bis-Phenol A epoxy coatings. In addition, organo-functional silicone polymers have been used to provide improved flexibility, but create recoatability issues. Siloxane resins and silicone polymers offer partial solutions to the limitations of bis-Phenol A epoxy coatings, but do not eliminate all of the limitations associated with this system. To fill this gap, a new class of organo-functional siloxane resins was developed by Dow Corning Corporation as epoxy resin crosslinkers providing flexible coatings with excellent recoat performance. Detailed work was done to compare modifications of a bis-phenol A epoxy paint using a variety of silicon-based technologies including aminopropyltrimethoxy silane, aminopropylmethyldiethoxy silane, methoxy-terminated siloxane resin, silanol-terminated siloxane resin, and amine-terminated siloxane resin.

Abstract:

Abstract The application of acid corrosion inhibitors is an absolute necessity to prevent damage to process equipment during acid cleaning operations. The use of organic acids and mineral acids that are not HCl has expanded because of environmental concerns and issues of compatibility with alloys such as stainless or duplex steel. Inhibitors which are used to protect the metals from corrosion by organic acids often contain a number of highly toxic compounds based on amine technology such as quaternary amines, amine ethoxylates, imidazolines and polyamides as well as sulfur compounds such as thiourea. Phosphate esters and organic boron compounds may also be used, which are not as acutely toxic as the amine compounds; however, in terms of ecological toxicity, it is easy to see that these do not make the green list. In addition, other additives used to formulate these inhibitors, such as nonyl phenol ethoxylates, are also toxic and have to be limited in their use. Several different organic acid inhibitors were tested which offer a non-toxic, low toxicity or green chemical profile. These were tested against several common organic acids used in industrial chemical cleaning, at a variety of temperatures and compared against the current top ranked organic acid inhibitor from our lab. Testing showed trends in the types of organic acid inhibitors that are effective as well the limits of their application.

Abstract:

Abstract Corrosion in crude distillation unit overhead lines is primarily caused by hydrochloric acid at the dew point. Various other contaminants including air, organic acids, H2S, NH3, tramp amines, HCN, mercaptans, phenols, etc. also play a role in overhead corrosion. Mitigation strategies include process solutions such as wash water systems and temperature control, and chemical solutions including amine-based neutralizers and film-forming inhibitors. Despite implementing these strategies, corrosion is invariably observed in the overhead system. Conventional “non-volatile” filmers rely on free liquid to cover the metallurgy. However, the complex nature of overhead geometry and fluid flow make complete metal coverage challenging. This necessitates a different strategy to achieve protection. Here, we present a first of its kind Vapor Phase Corrosion Inhibitor (VPCI) for protecting overhead systems. Several VPCI candidates were studied in the lab for performance, volatility, and risks (emulsification, pentane solubility, amine salt fouling, thermal stability). Promising VPCI was field trialed in several refineries.

Full text

Abstract:

Abstract An epoxy coating with excellent cathodic disbondment resistance performance is developed in this paper. Bisphenol A epoxy resin, bisphenol F epoxy resin, novolac epoxy resin and C9 petroleum resin were used as the resin system of coating. The orthogonal test of four factors at four levels was applied to select the amount of each resin. The mixed curing agent of polyamide and modified phenolic amine showed good performance. When the ratio of polyamide and modified phenolic amine was 2:1, the anti-cathodic disbonding performance of the coatings was the best. The optimized ratio of pigment to resin (pigment/binder ratio) is 1:1, which was concluded from the correlation between P/B (pigment/binder) ratio (0.75:1~1.5:1) and cathodic disbonding resistance performance. The final epoxy coating formulation with optimized resin, curing agent and pigment/binder ratio has excellent cathodic disbonding performance, which is only 3 mm of cathodic disbonding equivalent diameter after 48 hours cathodic disbondment test (-1.5V (vs. SCE), 65°C seawater).

Abstract This paper first presents a brief description of naphthenic acid corrosion and the main factors which influence its onset and severity. After a brief discussion of traditional control methods, it proceeds to a discussion of chemical inhibition, which is a relatively new control technique. Chemical inhibitors can be divided into two broad classifications: phosphorus-based and non-phosphorus-based. Three types of phosphorus-based inhibitors have been reported: amine-neutralized phosphate esters, alkaline earth phosphonate phenate sulfide plus trialkyl phosphate, and thiazolines plus di- and tri-alkyl phosphites. Non-phosphorus based inhibitors include: thiazolines, organic polysulfides, and sulfonated alkyl phenols. A description of each inhibitor and its effectiveness in the laboratory and field is presented.

Full text

Abstract:

Abstract Popular wisdom holds that abrasive blasted steel cleaned to a near-white metal finish (NACE 2/SSPC- SP10) or better provides the optimum performance for coatings applied to the substrate. This is certainly true for inorganic silicate coatings such as zinc silicates where the silicic acid from the binder will covalently bond with metallic iron. For organic coatings, however, in particular epoxy-amine coatings, the mechanism of bonding with metallic iron, other than van der Waals forces, is not known, if it exists at all. On the other hand, the mechanism of epoxy-amine coatings binding to iron oxide is well known, and consists of a strong Lewis acid-base interaction which may result in enhanced coating performance properties. This may indicate that applying an epoxy-amine coating over clean (i.e. without soluble salts) rusty steel could provide better corrosion mitigating performance than that achieved by using clean, white metal blasted steel. This study compares the accelerated corrosion performance of an alkylated phenolic polyamine cured epoxy (epoxy-phenalkamine) coating applied to abrasive blasted steel prepared to a NACE 1/SSPC-SP5 standard cleanliness and to substrates that have been allowed to rust in a variety of conditions, including varying soluble salt compositions and density. Performance properties evaluated included adhesion loss, scribe creep and cathodic delamination away from the scribe on the epoxy-phenalkamine coating. The mechanism of improved anti-corrosion performance of an epoxy-amine coating over rusty steel is examined in detail.

Abstract:

Abstract In the worldwide oil and gas industry, the application of epoxy phenolic coatings has been a dominant strategy to obtain high heat resistance from coatings and to mitigate corrosion under insulation (CUI) of both insulated carbon and stainless steel pipes operating up to 392°F (200°C). These coatings, however, are sensitive to over-application, prone to cracking, and costly to repair when damaged. Additionally, if applied below 50°F (10°C) epoxy phenolic coatings do not cure properly and can fail prematurely, and when applied close to this temperature, can impact shop heating costs, maintenance schedules, and productivity. The genesis and performance of a step change epoxy coating for high heat resistant service and CUI mitigation is investigated. Based on a novel amine epoxy technology platform this next generation high temperature coating simplifies coating specifications and is easy to apply on carbon and stainless steel pipe externals for both insulated (CUI) and non-insulated service. Tolerant of over-application, and possessing fast and subzero curing characteristics, the novel alkylated amine epoxy coating enhances shop productivity and reduces project costs, thereby eliminating several challenges seen with traditional epoxy phenolic coatings. This paper also describes another step change epoxy, a novel lining developed for the internals of tanks, pipes, vessels and railcars internals. A high film build, rapid curing, single leg spray applied modified polycyclamine cured epoxy (hereinafter MPCE), this lining was primarily developed for high temperature and high pressure immersion service in harsh oilfield services, and later for railcar internals. Aside from its high temperature resistant characteristics, the next step MPCE was formulated to possess a smooth and abrasion resistant surface with a low coefficient of friction and low surface energy, which markedly improved the flow properties of fluids and cargoes in tanks, pipes, vessels, and railcars.

Abstract:

Abstract Epoxy coatings have a long and successful track record in marine and protective coatings, due to the combined offerings of excellent corrosion and chemical resistance. As regional environmental drivers become firmly established, the industry is faced with the constant challenge of providing solutions which can comply with emerging VOC regulations. There is a continuous trend to move the technology from the so-called conventional paint to high solids coatings, and more recently, to ultra-high solids coatings [1]. At the same time the overall performance attributes associated with high performance epoxy systems need to be either maintained or improved depending on specific industrial application needs. Many current high solids epoxy systems use non-reactive plasticizers such as benzyl alcohol or alkyl phenols to enable full chemical conversion of the polymer matrix. While this approach allows for reduced solvent demand, such products do not always address the market need for extended service life. The use of fugitive plasticizers can cause the coating to lose its flexibility over time as the plasticizer leaches out. In order to address this, a different plasticization approach to lower solvent requirement and ensure complete cure is needed. This paper will review the basics of high solids epoxy coatings compared to conventional epoxy technologies, and describe the fundamental technical differences. It will also present new versatile amine curing agent technology that offers solutions to develop coatings compliant with stringent emission test accreditation, and at the same time, addresses many of the technical challenges associated with high solids systems. Furthermore, the absence of non-reactive plasticizers facilitates long-term conservation of the mechanical properties of the coating, and hence, helps deliver long-term asset protection.

Full text

Abstract:

Abstract In gas well corrosion treatment by batch application, it is essential to know an accurate inhibitor fall rate for assessing necessary shut in time to avoid formation damage from contact with inhibitor, and to ensure full coverage of the inhibitor on the internal tubing wall. A series of experiments to measure the inhibitor fall rate using a "gradiomanometer" tool have been conducted in nine (9) gas wells. One of the important parameters involved in the batch application is the corrosion inhibitor fall rate. This paper presents a study to determine the actual corrosion inhibitor fall rate in several tubing sizes and types, and at several different tubing pressures. However, the focus of this paper is on the methodology used to generate the data, not the data itself. The experiments were performed by locating the "gradiomanometer" tool just above the plug or above the liquid level in the well, and pumping the inhibitor into the well. Pressure differential indications between two sensors on the tool enabled the falling time to be measured, and the fall rate calculated. The tubings used for this experiments were from two types; one was internally coated using a type of “modified phenolic”, and the other was uncoated tubing. The generic chemistry of the corrosion inhibitor used for this experiment is “a partially neutralised C18+ long chain complex Amine”. The result indicated the average fall rate of 4521 ft/hr (0.383 m/s) for the uncoated tubing, and 5355 ft/hr (0.453 m/s) for the coated tubing, with an overall average of 4760 ft/hr (0.403 m/s). After rounding, these figures can be used for assessing the required shut in time when conducting batch corrosion treatment.

Abstract:

This research was aimed to develop an active film from chitosan film incorporated with green tea extract to enhance antioxidant and antimicrobial properties in order to be used for food shelf life extension. The experiments were divided into 3 parts. Firstly, chitosan-based film preparation and modification were determined. The results suggested that the optimum chitosan films could be prepared from 2% chitosan in 1% acetic acid. However, the chitosan film was brittle and had low flexibility. Mechanical property of chitosan film was modified by adding different concentrations of glycerol, as a plasticizer, including 0, 10, 20, 30, 40 and 50% (w/w of chitosan). The effect of plasticizer concentration on the mechanical properties of the chitosan film was determined by measuring their tensile strength, elongation at break, thickness, surface colors and water vapor transmission rate. The results showed that 30% glycerol was the optimum concentration to improve flexibility, while maintaining tensile strength and other physical properties of the film. Secondly, chitosan-based film was incorporated with green tea extract (GT) in order to improve film’s antioxidant and antimicrobial properties. The optimum concentration of green tea extract was then determined by adding 0, 2, 5, 10 and 20% (w/v) of green tea in film-forming solution, and tensile strength, elongation at break, water vapor permeability (WVP), density, total phenolic compounds (TPC), radicals scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH) of the film were determined. Fourier Transform Infrared (FTIR) spectrometry was carried out to observe the potential modifications of the chitosan films when incorporated with GTE. The ability to inhibit Staphylococcus aureus TISTR 118, Salmonella enteritidis DMST 17368, Escherichia coli TISTR 780 and Pseudomonas fluorescens TISTR 358 was conducted using agar diffusion method. It was found that WVP and lightness (L) decreased, while density, TPC, DPPH scavenging activity, redness (a), and yellowness (b) increased with increasing green tea concentration. The results also showed that films containing green tea extract had inhibition zone and could inhibit bacterial growth underneath film, while chitosan-alone film had no inhibition zone. The results suggested that incorporation of GT into chitosan films improved mechanical and water vapor barrier properties and enhanced polyphenolic content, antioxidant activity and antimicrobial property of the films. Changes in the FTIR spectra of the chitosan films were observed when GTE was incorporated, suggesting some interactions occurred between amine group of chitosan and hydroxyl group of green tea polyphenols. Lastly, the chitosan film containing green tea extract (CGT-film) was used as an active film for shelf life extension of pork sausage. Qualities of pork sausages wrapped with CGT-film were compared with those wrapped with chitosan-alone film without green tea incorporation (C-film) and those without chitosan film wrapping (Control). Changes in the physical qualities including color values and texture, the chemical qualities including pH and thiobarbituric value (TBA), the microbiological qualities including total plate count, yeasts/moulds, and lactic acid bacteria were determined throughout the storage. The sensory qualities including odor, color, slime formation, and overall acceptance were also evaluated using Quantitative Descriptive Analysis. The results showed that samples wrapped with CGT-film had higher cutting force, lightness and yellowness values, but lower TBA and microbial growth than those wrapped with C-film and control. Based on microbiological analysis and sensory evaluation, control samples and those wrapped with C-film had shelf life of less than 12 and 20 days, respectively. Samples wrapped with GCT-film had better qualities than other samples and had shelf life of up to 20 days at 4℃. Incorporation of GT into chitosan film could enhance the antioxidant and antiomicrobial properties of the film. CGT-film reduced the lipid oxidation and inhibited microbial growth and, consequently, could maintain qualities and extended shelf life of the pork sausage.
