Abstract:

Purpose The purpose of this paper is to use the bio-based resource as the starting material for the synthesis of azo dye. Cardanol is one of the most used bio-based resources for carrying out the synthesis of various compounds having numerous end applications. The study presents an attempt to develop an azo dye from Cardanol having end applications in pH-responsive dyes. Design/methodology/approach The cardanol was sulfonated to block the para position by which ortho positioned hydroxyl group after diazotization and coupling will provide necessary pH-sensitivity. The diazotization of two naphthalene derivatives, i.e. 1-naphthol-8-amino-3,6-disulfonic acid (H-acid) and 7-amino-4-hydroxy-2-naphthalene sulfonic acid (J-acid) was carried out using the standard practice, and the diazotized compounds were coupled with the sulfonated cardanol. The obtained dyes were characterized by Fourier transform infrared, nuclear magnetic resonance, carbon-hydrogen-nitrogen-sulfur analysis and hydroxyl value. The colour properties were checked using UV-vis spectrophotometry and density functional theory, while thermogravimetric analysis was used for the thermal degradation studies of both the dyes. Findings Water-soluble cardanol-based azo dyes were prepared successfully having good thermal stability, and the obtained results are being presented in this paper. Originality/value The originality lies between the use of cardanol as a bio-based resource for the synthesis of azo-dye and the obtained azo-dye has the pH-sensitivity.

Abstract:

In this paper, a micro-fluidic optimized process for the continuous flow synthesis of azo compounds is presented. The continuous flow synthesis of Sudan II azo dye was used as a model reaction for the study. At found optimal azo coupling reaction temperature and pH an investigation of the optimum flow rates of the reactants for the diazotization and azo coupling reactions in Little Things Factory-MS microreactors was performed. A conversion of 98% was achieved in approximately 2.4 minutes and a small library of azo compounds was thus generated under these reaction conditions from couplers with aminated or hydroxylated aromatic systems. The scaled up synthesis of these compounds in PTFE tubing (i.d. 1.5 mm) was also investigated, where good reaction conversions ranging between 66–91% were attained.

Abstract:

This paper presents the synthesis of penta-bismuth hepta-oxide nitrate, Bi5O7NO3, via the chemical precipitation method. After calcination, the precipitate was characterised by several methods, which included X-ray powder diffraction, X-ray photoelectron spectroscopy, scanning and transmission electron microscopy, Fourier transform infrared, thermogravimetric analysis, BET surface area and pH drift method to determine the pH of point of zero charge (pHpzc). The study results revealed that Bi5O7NO3had an orthorhombic crystal structure, a surface area of 1.6 m2 g-1 and a point of zero charge at pH 9.7. The chemical state of Bi5O7NO3indicated the presence of three oxidation states of bismuth centre. Furthermore, the decolourization ability of Bi5O7NO3to remove the azo dye was also evaluated. Although it had lower surface area, the removal efficiency was extremely good. This finding suggests that Bi5O7NO3could be used as a promising adsorbent for azo dye removal. The XPS spectra showed that the accumulation of dye onto Bi5O7NO3could be due to the anion exchange process, suggesting the birth of a new anion exchanger for azo dye removal.

Abstract:

The present paper presents the obtaining and the characterization of a new complex acid dye by combining the transition metal Cu (II) with an azo acid dye, namely Amido Black 10B (C.I. 20.470), as ligand. The ligand and the resulted new azo complex were characterized by FT/IR spectroscopy, UV-Vis spectroscopy, AAs spectrometry, thermal analysis, and PXRD spectrometry. The structure of the ligand and the structure of the new synthesized copper complex were elucidated by all the above mentioned analysis methods. The formation of the azo metal complex with Cu(II) was confirmed by UV-Vis spectrum. Thermogravimetric and spectral analysis reveal its different stability in the air and nitrogen atmosphere, with high nitrogen stability. The PXRD analysis shows crystalline structure for the copper complex. At the same time, the color analysis was performed for the ligand and the synthesized complex in powder by means of UV-Vis CIEL*a*b* color space parameters, under the CIE recommended illuminants: D65 (natural day light), A (incandescent light) and F2 (fluorescent light) under the standard 10� observer angle. An important color phenomenon, namely metamerism, was highlighted for the complex, as well. Due to the presence of the Cu (II) ions, this azo complex presents a different color, calculated by the color differences AE*ab and AC*, a superior saturation and color strength than its ligand.

Abstract:

This article includes the synthesis of heterocyclic azo dye of theophylline by coupling diazonium salt of 4-chloroaniline with theophylline which is, namely, 8-(1-(4-chlorophenyl)azo)theophylline (CPAT). The complexes of cobalt and nickel were prepared by reacting their ions with CPAT ligand in ethanol under 1 : 2 ratio metal-ligand. The CPAT ligand and its complexes were characterized by elemental analysis, infrared spectrometry, electronic absorption spectroscopy, molar conductivity, and magnetic moment. The cobalt and nickel complexes show octahedral geometry having general formula [M(CPAT)2Cl2]. This article addresses the properties of CPAT dye such as photochromic properties. The CPAT dye exhibited obvious and desired changes under irradiation with visible light (405 nm), high sensitive for pH changes which refer to its ability to be analysis indicator. CPAT dye exhibited solvatochromic properties presenting red shift with polar solvent. The CPAT and its complexes show interesting antibiological activities towards Staph. aureus and E. coli bacteria and Aspergillus fungi.

Abstract:

Diazotisation and aso=coupling reactions have been studied and the results are reported. A kinetic study of the acid catalysed diazotisation of various aniline derivatives has been made. The substrates considered were 2,4-dinitro-aniline, 4-nitroaniline, sulphanilaraide (aniline-4-sulphonamide) and sulphanilic acid (aniline-4-sulphonic acid). A new pK(_a) value of l.4 is reported for sulphanilamide. A study of the diazotisation of sulphanilic acid and sulphanilamide in the presence of Cl¯, Br¯, SCN¯, and SC(NH(_2))(_2) shows that the general catalytic trend Cl¯ < Br¯, SCN¯ < SC(NH(_2))(_2) is followed; whereas for the corresporaing nitrosating agents the general reactivity trend NOCl > NOBr >; NOSCN >NOS(^+)C(NH(_2))(_2) is followed. No catalysis was observed in the case of 2,4=dinitroaniline and this has-been interpreted in terms of a rapid reversible nitrosation in which the rate of the denitrosation step is greater than the rate of decomposition of the intermediate nitrosammonium ion. The bimolecular rate constants obtained for sulphanilic acid and sulphanilamide approach the diffusion controlled limit for this process in the case of NOCl and NOBr, Also reported is a study of the diazotisation of two heteroaromatic amines: 2-amino-5-nitrothiazole and 3-amino-l,2,4-triazoleo Catalysis by acid and the nucleophiles Cl¯ and SCN¯ has been observed. The catalytic and reactivity trends described above have been noted for reaction of these heteroaroraaticso The Pk(_a) value for 2-amino—5-nitrothiazole has-been determined and agrees well with the literature values. In addition to the above studies of diazotisation mechanisms, results are reported of a study of the leaving abilities of various electrofugal leaving groups X during ipso=coupling of 4=nitroaniline with 4-X,N- dimethylanilineso The sequence of leaving abilities has been determined by product yield studies. Rate constants for attack of ArN(^+)(_2) have also been determined. It is suggested that a substrate molecule (X-Ar-NMe(_2)) acts as a base in removing the group X from the Wheland intermediate.

Abstract:

In this research, the ability of anaerobic and aerobic biological sludges to reduce and stabilize azo dye compounds was studied. Synthetic dye solutions and an industrial textile wastewater were both treated using anaerobic and aerobic biomass, separately and in sequential step-treatment processes. The primary objective was to reduce the wastewater color to an intensity that complies with the Virginia Pollutant Discharge Elimination System (VPDES) permit level. This level is set at 300 American Dye Manufactures Institute (ADMI) units. Further objectives were to achieve reductions in the total kjehdal nitrogen (TKN) and total organic carbon (TOC) in the wastewater. Anaerobic and aerobic treatment systems were both effective in reducing the wastewater color; however, anaerobic treatment generally produced the greatest color removal. Anaerobic/aerobic (ANA/AER) sequential step-treatment provided the best reductions in ADMI color, TKN and TOC. Anaerobic/aerobic/anaerobic/aerobic (ANA/AER/ANA/AER) sequential step-treatment did not yield greater reductions in ADMI color, TKN, or TOC as compared to ANA/AER sequential step-treatment.

Abstract:

12 azo dye ligands LI-LI2 that are used in the inkjet printer industry have been synthesised and characterised. The dyes L5B and L3765 were supplied as gifts by the chemical company Avecia. All dyes were fully examined by IH NMR, 13e NMR, IR spectroscopy, electrospray mass spectroscopy, atomic absorption spectroscopy, UV-Visible spectroscopy and microanalyses. Melting points were also determined. pKa values have been determined by visible spectroscopy for the dyes PAN(Aldrich), L7, L3765, Ll, L5 and L5B. Stability constant measurements have been attempted for the Ni(II) complexes of PAN, LI and L5 using UV-Visible spectroscopy. Single wavelength stopped-flow kinetic studies of the reactions of Ni(II) with PAN(Aldrich), PADA(Aldrich), SUDAN I(Aldrich), L3765 and L7 were carried out. Multi wavelength stopped-flow kinetic studies of the reactions of Ni(II) with L 1, L 7, L5 and L5B were examined and rate constants for complex formation (kf ) were determined. Rates of dissociation of [Ni(PAN)2] using ligand exchange with either EDTA or 2,2' :6' ,2" -Terpyridine (Terpy) were investigated using UV -Visible spectroscopy. Relative stabilities of [Ni(II)(PAN)t, [Ni(II)(L 7)] and [Ni(II)(L3765)r have been determined. Dissociation of Ni(II) complexes of Ll, L5, L5B, L6, PAN, L7 and L3765 using excess Terpy have been studied using UV -Visible spectroscopy and relative stabilities have been compared.

Part 1. A new chemodosimeter 1-(4-(4-trifluoromethyl phenyldiazenyl) phenyl)-3-(pyren-1-yl)thiourea (20) was prepared, and its chromogenic and fluorogenic behaviors toward various metal cations were investigated. Receptor 20 shows exclusive a response toward Hg2+ ion and also distinguished Hg2+ ion from other metal cations by color changes in DMSO aqueous solution (DMSO/H2O = 9/1, v/v). Additionally, receptor 20 also exhibited a pronounced Hg2+-induced fluorescence enhancement. Thus, the receptor 20 can be used as a colorimetric and fluorescent chemodosimeter for the determination of Hg2+ ion. Part 2. The passionvine mealybug, Planococcus minor is a serious pest of economically important crops in Taiwan. The effective control of this pest is limited by only using pesticides. Also the side effects such as the insect resistance, the pesticide residue and the environment contamination will be occurred. To avoid these side effects, the nontoxic sex pheromone of the passionvine mealybug is chosen instead. The sex pheromone of Planococcus minor was identified as (E)-2-isopropyl-5-methyl-2, 4-hexadienyl acetate (1). The synthesis of this sex pheromone would produce two isomers in the products. This caused some difficulties and troublesome. On our hand, due to the high cost of the starting material and the low yield of the product, the development of a cost-effective, high yield and operationally simple synthetic approach is necessary. In this report a series of new palladium reagents are used for the synthesis of the intermediate, 2-(5-Methylhex-4-en-2-ynyloxy)- tetrahydro -2H-pyran (8). In addition, the subsequent coupling reaction can also be successfully preceded by using FeCl3. This improved synthetic method can overcome the above limitations. Receutly, the effective control of this pest in the tests by using this pheromone is achieved. This indicates that the synthesized pheromone has strong attraetiveness for the passionvine mealybug.

Abstract:

The limited availability of fresh water is a global crisis. The growing consumption of fresh water due to anthropogenic activities has taken its toll on available water resources. Unfortunately, water bodies are still used as sinks for waste water from domestic and industrial sources. Azo dyes account for the majority of all dye stuffs, produced because they are extensively used in the textile, paper, food, leather, cosmetics, and pharmaceutical industries. Bacterial degradation of azo dyes under certain environmental conditions has gained momentum as a method of treatment, as these are inexpensive, eco-friendly, and can be applied to wide range of such complex dyes. The enzymatic approach has attracted much interest with regard to degradation of azo dyes from wastewater. The oxido-reductive enzymes are responsible for generating highly reactive free radicals that undergo complex series of spontaneous cleavage reactions, due to the susceptibility of enzymes to inactivation in the presence of the other chemicals. The oxidoreductive enzymes, such as lignin peroxidase, laccases, tyrosinase, azoreductase, riboflavin reductive, polyphenol oxidase, and aminopyrine n-demethylase, have been mainly utilized in the bacterial degradation of azo dye. Along with the reductive enzymes, some investigators have demonstrated the involvement in some other enzymes, such as Lignin peroxides and other enzymes. This chapter reviews the importance of enzymes in dye degradation.

Abstract:

Remediation of environmental pollution has become a hot issue in the world. Environmental pollution, mainly caused by toxic chemicals, includes air, water, and soil pollution. This pollution results not only in the destruction of biodiversity, but also the degradation of human health. Textile industrial effluent often contains the significant amount of synthetic and toxic dyes. Some dyes are water-soluble, dyes such as azo dyes, sulfonated azo dyes, etc. Hazardous effect of dyes results in the formation of tumor, cancer, liver or kidney damage, insomnia, diarrhea, nausea, vomiting, dermatitis, chronic asthma, coughing, headaches, and allergies in humans and also inhibit growth of bacteria, protozoan, plants, and different animals. A range of wastewater treatment technologies have been proposed that can efficiently reduce toxic dyes to less toxic forms such as nanotechnology. In this chapter, the authors give an overview of the various aspects of nanotechnology to remediate industrial textile dye effluents.

Abstract:

Synthetic dyes cause hazardous health-related problems in humans and affect the biological system underwater. They also have a negative impact on the nutritive value of soils and thereby on crops. Until now there is no effective method to remove the harmful component of dyes from the environment. However, the integrated treatment using bio agents with implication of physical and chemical processes can be effective in the treatment of dye effluents. From the complex azo dyes to their dissociation via thallophytes is a new scope for sustenance. Various studies have supported that laccases have the capability to degrade synthetic dyes that have different chemical structures. Thallophytes have been used to degrade the complex dyes with varying ranges of temperature and pH. Thallophytes have recently been used to treat the textile effluents with effective higher temperature and alkaline pH with decreasing BOD and thus cleaning them from environment in an eco-friendly and cost-efficient manner.
