Abstract:
ABSTRACT Enzymes of the AlkB and CYP153 families catalyze the first step in the catabolism of medium-chain-length alkanes, selective oxidation of the alkane to the 1-alkanol, and enable their host organisms to utilize alkanes as carbon sources. Small, gaseous alkanes, however, are converted to alkanols by evolutionarily unrelated methane monooxygenases. Propane and butane can be oxidized by CYP enzymes engineered in the laboratory, but these produce predominantly the 2-alkanols. Here we report the in vivo-directed evolution of two medium-chain-length terminal alkane hydroxylases, the integral membrane di-iron enzyme AlkB from Pseudomonas putida GPo1 and the class II-type soluble CYP153A6 from Mycobacterium sp. strain HXN-1500, to enhance their activity on small alkanes. We established a P. putida evolution system that enables selection for terminal alkane hydroxylase activity and used it to select propane- and butane-oxidizing enzymes based on enhanced growth complementation of an adapted P. putida GPo12(pGEc47ΔB) strain. The resulting enzymes exhibited higher rates of 1-butanol production from butane and maintained their preference for terminal hydroxylation. This in vivo evolution system could be useful for directed evolution of enzymes that function efficiently to hydroxylate small alkanes in engineered hosts.

Cuticular waxes from leaves and fruit capsules of Papaver alpinum sensu Markgr., P. bracteatum Lindl., P. dubium L., P. nudicaule L., P. orientale L., P. rhoeas L., P. somniferum L., and Eschscholtzia californica Cham. were investigated. They consisted of n-alkanes (< 19%), alk-1-ylesters (< 18%), alk-2-ylesters (< 6%), alkanals (< 19%), secondary alkanols (21–71%, mainly nonacosan-10-ol), triglycerides (< 6%), primary alkanols (2–33%), alkanediols (2–23%, mainly isomeric nonacosanediols), alkanoic acids (< 8%), and alkaloids (< 12%). In addition, minor amounts of iso- and anteiso-alkanes, alkanoic acid methyl esters, esters of alkan-10-ols, benzyl- and phenyl-ethylalcohol, triterpenols and phytosterols, ketols, and ketones were detectable. The isomer composition of the secondary alkanols and their alkanediol, ketol, and ketone derivatives is used to deduce the probable sequence of steps in the respective biosynthetic pathways. Keywords: Papaver, Eschscholtzia, Papaveraceae, cuticular wax, secondary alkanols, biosynthesis.

Abstract:
H+ permeability (PH) of brush border membrane vesicles isolated from rabbit renal cortex was measured from the rate of collapse of preformed pH gradients using acridine orange fluorescence quenching. n-Alkanols increased PH from 0.005 to 0.1 cm/s in a dose-dependent manner. At 25 degrees C, PH increased to 0.01 cm/s at [n-alkanol] = 90 mM (butanol), 30 mM (pentanol), 7 mM (hexanol), and 1.8 mM (heptanol). Activation energy (Ea) of PH was 21.6 kcal/mol (5-50 degrees C), which decreased to 18.5 kcal/mol in the presence of either 200 mM butanol or 12 mM hexanol. Membrane fluidity was estimated from diphenylhexatriene anisotropy (r). n-Alkanols decreased r from 0.25 to 0.18 in a dose-dependent manner. At 25 degrees C, r = 0.22 at [n-alkanol] = 200 mM (butanol), 27 mM (pentanol), 9.5 mM (hexanol), and 2 mM (heptanol). The effects of n-alkanols on PH and r correlated well with known n-alkanol lipid-water partition coefficients. Similar increases in PH and decreases in r were observed for nonalkanol lipid anesthetics. The effects of n-alkanols on the Na+-H+ antiporter and on osmotically driven water transport were also studied. At concentrations of n-alkanol that resulted in a 10-fold increase in PH, there was no significant effect on either Na+-H+ exchange or water transport. These results suggest a lipid pathway for brush border H+ diffusion that is distinct from both the Na+-H+ antiporter and the water transport pathway.

Abstract:
Solubilities of solute gases and vapours, as log L, where L is the Ostwald solubility coefficient, in the alkan-1-ols from methanol to decan-1-ol have been correlated through the solvation equation of Abraham. It is shown that there is a regular progression of solvent properties from methanol to decan-1-ol, except for the solvent hydrogen-bond basicity that remains the same along the series, and, indeed, is the same as that of water. A slightly different solvation equation is used to correlate the partition of solutes from water to the dry alkanols. For the longer chain alkanols, the coefficients in the solvation equations approach those in equations for partition from water to the wet (water-saturated) alkanols, showing that the solvation properties of the wet and dry alkanols are quite close for the higher alkanol homologues.

Abstract:
The Henry reaction, the coupling of a nitro alkane and a carbonyl group, is an important C–C bond-forming reaction giving nitro alkanols, which are useful, versatile intermediates in synthetic organic chemistry and for the pharmaceutical industry. Among the catalysts employed in the Henry reaction, transition metal complex catalysts play an important role. Transition metal complexes, including small molecules and nanoparticles, catalyze the asymmetric Henry reaction efficiently and in most of the cases give chiral nitro alkanol products in good yield and enantiomeric excess. This review summarizes transition metal complex catalysts, metal-free organic catalysts and nanoparticle catalysts for the Henry reaction.

Abstract:
Thermodynamic properties: vapour–liquid equilibria, VLE, or excess enthalpies, HE, for a set of 21 ternary mixtures of the type 1-alkanol + n-alkanone + organic solvent are studied in the framework of the DISQUAC group contribution model. This treatment is extended to the binaries involved. The DISQUAC analysis is developed on the basis of binary interactions only, that is, ternary interactions are neglected. Most of the interchange coefficients needed are available in the literature. The average relative standard deviations are 0.026 for pressure in the VLE (12 systems) and 0.098 in the HE (9 systems). The discrepancies observed are briefly discussed. Keywords: 1-alkanols, n-alkanones, group contribution, liquids, ternary systems, thermodyamics.

Abstract:
In this work, the refractive indices (nD) of binary mixture of diisopropylamine (DIPA) and tributylamine (TBA) (as sec- and tert-amines) with alkanol (methanol, ethanol, 1-propanol, 2-propanol) were measured from 298.15 K to 318.15 K. The sec- and tert-amines were selected to study the effect of branching at N-atom of amine on intermolecular interactions with alkanols having different chain length. It was found that the TBA interacts strongly with alkanol in comparison to DIPA due to steric hindrance offered by isopropyl group at N-atom. Various mixing rules were applied to evaluate the refractive index compared well with the experimental refractive indices data for the present binary mixtures. The experimental refractive indices was also fitted to Redlich-Kister polynomial.

Abstract:
Binary mixtures of 1-methyl pyrrolidin-2-one (NMP) with alkanes, benzene, toluene, 1-alkanol, or 1-alkyne have been investigated in the framework of the DISQUAC model. The reported interaction parameters change regularly with the molecular structure of the mixture components. The model consistently describes a set of thermodynamic properties, including liquid–liquid equilibria, vapor–liquid equilibria, solid–liquid equilibria, and molar excess enthalpies. A brief comparison of the DISQUAC results and those obtained from the UNIFAC and ERAS models is presented. The experimental excess enthalpies are better represented by DISQUAC than by UNIFAC because this quantity strongly depends on molecular structure. For NMP + alkane mixtures, the liquid–liquid equilibria data are also better represented by DISQUAC, while UNIFAC more accurately describes the vapor–liquid equilibria measurements at temperatures close to the critical point. This result suggests that a mean field theory is not able to represent simultaneously, with the same set of interaction parameters, liquid–liquid and vapor–liquid equilibria at the mentioned temperatures. ERAS fails when treating mixtures with 1-alkanols. This has been attributed to the strong dipole–dipole interactions between NMP molecules, characteristic of the investigated systems. Mixture structure is briefly studied in terms of the concentration–concentration structure factor.Key words: thermodynamics, NMP, organic solvent, self-association, dipole–dipole interactions.

Abstract:
To characterize the cellular stress by n-alkanols with different alkyl chain lengths in Escherichia coli, we investigated how n-alkanols damage cell envelope permeability and whether they enhance the promoter activity of the envelope stress response regulator, σE, by using variants of green fluorescent protein (GFP). By using E. coli cells having GFPuv expressing and localizing in the cytoplasm, the inner membrane, and the periplasm, after exposure to n-alkanols, the fluorescent intensity of GFPuv released from cells was examined. Our data showed that at the similar levels of cell death of about 90–97%, ethanol, a short-chain alkanol, at a concentration of 20% damaged the outer membrane more greatly than the inner membrane, whereas a longer-chain alkanol of pentanol at a concentration of 1.125% damaged both of the outer and inner membranes. Then we investigated the envelope stress response to n-alkanols by σE factor by ratiometric analysis of rpoE promoter activity for the downstream GFPuv expression referenced to that of housekeeping sigma 70 (σ70 ) recognizing lacUV5 promoter for red fluorescent protein (RFP) expression. The results indicated that the relative activity of rpoE promoter by pentanol was much greater than that of ethanol. The degree of its sensitization by rpoE deficiency was much more remarkable for cells treated with pentanol than for those with ethanol. The results suggest that the response of the σE plays a significant role in the membrane integrity and survival of E. coli cells treated with n-alkanols depending on the alkyl chain length of the molecule.

Abstract:
The complexes trans–[Pd(COOR)(H2O)(PPh3)2](TsO) (R = Me, Et, nPr, iPr, nBu, iBu, secBu) and trans–[Pd(COOR)nX2–n(PPh3)] (R = Me, n = 1, 2; X = ONO2, ONO, OTs, Br. R = iPr, n = 1, X = Cl, Br) have been synthesised and characterised. Most of them have been used as catalyst precursors for the oxidative carbonylation of MeOH, selective to dimethyloxalate, using p–benzoquinone (BQ) as an oxidant. BQ changes properties of the reaction centre. When using iPrOH in place of MeOH, high activity and selectivity toward diisopropyloxalate have been achieved using trans–[PdX2(PAr3)2] with strongly coordinating X (Br), in presence of a base (NEt3 or PAr3–BQ adduct) and of an excess of LiBr. The slow step of the catalysis (RDS) might be the reoxidation of Pd(0), which is formed in the product–forming step. Using [PdX2(P-P)] the best performance has been achieved with weakly coordinating X (TsO) and using P-P of relatively wide bite angle but with cis–geometry. The RDS is related to the nature of P-P.
Sono stati sintetizzati e caratterizzati i complessi trans–[Pd(COOR)(H2O)(PPh3)2](TsO) (R = Me, Et, nPr, iPr, nBu, iBu, secBu) e trans–[Pd(COOR)nX2–n(PPh3)] (R = Me, n = 1, 2; X = ONO2, ONO, OTs, Br. R = iPr, n = 1, X = Cl, Br). Molti sono stati utilizzati come precursori catalitici nella carbonilazione ossidativa di MeOH, selettiva a dimetiloxalato, impiegando p–benzochinone (BQ) come ossidante. Il BQ modifica le proprietà del centro di reazione. Con iPrOH al posto di MeOH si ottengono elevate attività e selettività a diisopropyloxalato utilizzando trans–[PdX2(PAr3)2] con X fortemente coordinanti (Br), in presenza di base (NEt3 o PAr3–BQ) e di LiBr in eccesso. Lo stadio lento della catalisi (RDS) potrebbe essere la riossidazione del Pd(0) che si forma nello stadio di formazione dell’ossalato. Con [PdX2(P-P)] le migliori prestazioni sono state ottenute con X debolmente coordinanti (TsO) e con P-P ad angolo di morso relativamente ampio ma di geometria cis. L’ RDS dipende da P-P.

Abstract:
Since the identification of bile acids as natural ligands for FXR and TGR5 receptors, huge interest has arisen in this field, including the synthesis of semi-synthetic bile acid derivatives to increase binding potency and selectivity. Fluorine introduction is an attractive strategy in drug design and property optimization. This thesis describes the synthesis of fluorinated analogues of bile acids and the lead compound 6-ECDCA. Interesting observations of effects of fluorination on crystal packing modes will also be discussed. Another important application of fluorination is lipophilicity (logP) modulation. However, logP measurement of non-UV active compounds is rather cumbersome and hampers research toward the understanding how aliphatic fluorination influences lipophilicity. Over the course of this thesis, a novel and straightforward method was developed for accurate measurement of lipophilicity of fluorinated compounds by using 19F NMR. Unlike many other methods, there is no requirement of UV activity for quantification, or the need for calibration curves for logP estimation. Using this method, logP values for a large number of fluorinated compounds were determined. Interesting effects and trends from different fluorination patterns were observed, along with the impact of stereochemistry on lipophilicity.

Abstract:
Le but de ce travail est d'étudier l'extraction de composés organiques de solutions aqueuses par pervaporation sous l'angle du transfert de matière dans la membrane; l'équilibre de sorption et la diffusion de l'eau et d'une série d'alcanols (éthanol à pentanols) dans le polydimethylsiloxane (PDMS) ont été étudiés. La théorie de Flory-Huggins classique ne permet pas de décrire correctement les isothermes de sorption obtenus; une analyse des données d'équilibre, basée sur un critère thermodynamique (Zimm & Lundberg), montre que les molécules d'alcanols ont une tendance à l'autoassociation dans le PDMS (formation de clusters). Les résultats sont correctement décrits par une nouvelle approche mécanistique, postulant l'existence d'affinités élémentaires entre les molécules de solvant et la matrice polymère d'une part, les molécules congénères d'autre part; le modèle conduit à une équation d'équilibre contenant deux paramètres ajustables qui permet la description correcte de nombreux systèmes binaires dans les polymères. La diffusion d'un perméant unique dans le PDMS a été étudiée par la technique de perméation de vapeur; la tendance à la décroissance des coefficients de diffusion avec la fraction volumique en pénétrant correspond qualitativement à l'ordre de tendance à la formation de clusters, dégagé de l'étude de sorption. Dans le dernier chapitre, l'influence de la concentration en alcool et de la température de la charge sur les flux partiels de pervaporation est présentée

Abstract:
The interfacial thermal resistance of 11-mercaptoundecanol (-S(CH2)11OH) self-assembled monolayer (SAM) adsorbed on Au(111) substrate and water was investigated using nonequilibrium molecular dynamics simulations. The interfacial thermal resistance was found to be a half of that in the system which consists of 1-dodecanthiol (-S(CH2)11CH3) SAM adsorbed on Au(111) and toluene [Kikugawa G. et al., J. Chem. Phys. (2009)]. The effective thermal energy transfer originates from hydrogen-bond structure between the SAM and water molecules in spite of weak structurization of water molecules near the SAM surface.

Abstract:
The production of carbon-neutral liquid fuels from renewable biomass has attracted worldwide interest in an age of depletion of fossil fuel reserves and pollutions caused by utilization of fossil petroleum. Currently, commercial bio-oil production technologies include bio-ethanol, bio-diesel and pyrolysis bio-oil. But, these bio-oils mainly consist of alcohols and aromatic chemicals rather than alkanes of the main components of gasoline and diesel. Direct utilization of these bio-oils can corrode car engines as well as emitting large unburned hydrocarbons particles through automotive combustion system. Therefore, in this study, catalytic hydrothermal conversion (CHTC) of glucose to alkanes in a single batch reactor was investigated with respect to effects of conversion parameters such as initial pressure of process gas H2, pH level of aqueous solution and catalysts on alkane yields and compositions. Results showed that the highest alkane yield of 21.6% (based on the mol of the input glucose) was obtained at 265 °C, with 300 psi of H2 process gas, 0.5 g catalyst of 1w%. Pt/Al2O3 and a residence time of 15 h. The alkane yield was significantly influenced by the initial pressure of H2, which increased with increasing H2 pressure. On the other hand, the alkane yields first increased and then decreased with pH levels. Also, more alkanes were produced by Pt/Al2O3 than Pd/Al2O3. Regarding alkane compositions, high initial pressure of H2 favored the production of relatively heavy C3–4 alkanes. With 300 psi of initial H2, C3H8 and C4H10 accounted for 75% of the total produced alkanes. All of the experimental data in this study lead to one conclusion that petroleum alkanes can be directly produced from glucose.

Abstract:
Natural waxes are valuable industrial products consisting of complex chemical mixtures. To probe the structure−function role of select constituents, model n-alkanes, alcohols, aldehydes, and fatty acids of C18−19, C22−23, and C26−27 carbon chain lengths were synthesized and analyzed via calorimetry and X-ray powder diffraction. Pure compounds and binary mixtures crystallized into monoclinic (M), triclinic (T), and orthorhombic (O) lattices or combinations thereof. The C26 aldehyde formed an O lattice and exhibited one solid−solid phase transition similar to n-alkanes. The water vapor permeability (WVP) of model systems cast as films was determined. For pure compounds, WVP decreased in the following order: fatty acid > even n-alkane > odd n-alkane > alcohol > aldehyde. Increasing carbon chain length, which translates to increasing unit cell volume, decreased WVP. Binary mixtures generally exhibited a more complex relationship with WVP. These findings may be applicable to the agricultural postharvest, pharmaceutical, and paperboard coating industries.

Full text
Abstract:
Abstract In a recent study, we observed that the diffusion coefficient of common hydrocarbons in crude oils are more affected by the presence of different hydrocarbon components than the effect of confinement. Based on our previous observations, in this study, we investigated the efficiency of smaller-chain alkane injection into oil-soaked sandstone pores to dilute the oil with alkane. We used molecular dynamics simulations of C2, C3, C4 and C5 as well as a mixture of C3 and C4 to rank the effects of different alkanes on the diffusion and distribution of oil molecules in pore. As water-alternating-alkane injection would bring water into the pores, our simulations included water. Our results indicate that alkane injection into sandstone reservoirs has a significant potential due to the fact that it effectively dilutes the oil. Water always wets quartz surface relative to the oils. Injection of water therefore should be effective in detaching oil molecules on the surface. Presence of water layers did not affect the diffusion coefficients of oil molecules.

Abstract:
Alkanes such as methane, ethane, and propane make up a large portion of most natural gas fuels. Natural gas is the primary fuel used in industrial gas turbines for power generation. Because of this, a fundamental understanding of the physical characteristics such as the laminar flame speed is necessary. Most importantly, this information is needed at elevated pressures to have the most relevance to the gas turbine industry for engine design. This study includes experiments performed at elevated pressures, up to 10-atm initial pressure, and investigates the fuels in a pure form as well as in binary blends. Flame speed modeling was done using an improved version of the kinetics model that the authors have been developing over the past few years. Modeling was performed for a wide range of conditions, including elevated pressures. Experimental conditions include pure methane, pure ethane, 80/20 mixtures of methane/ethane, and 60/40 mixtures of methane/ethane at initial pressures of 1, 5, and 10 atm. Also included in this study are pure propane and 80/20 methane/propane mixtures at 1 and 5 atm. The laminar flame speed and Markstein Length measurements were obtained from a high-pressure flame speed facility using a constant-volume vessel. The facility includes optical access, a high-speed camera, a schlieren optical setup, a mixing manifold, and an isolated control room. The experiments were performed at room temperature, and the resulting images were analyzed using linear regression. The experimental and modeling results are presented and compared to previously published data. The data herein agree well with the published data. In addition, a hybrid correlation was created to perform a rigorous uncertainty analysis. This correlation gives the total uncertainty of the experiment with respect to the true value rather than reporting the standard deviation of a repeated experiment. Included in the data set are high-pressure results at conditions where in many cases for the single-component fuels few data existed and for the binary blends no data existed prior to this study. Overall, the agreement between the model and data is excellent.

Abstract:
Alternative liquid fuels can contain hydrocarbons of different types and chain lengths and the fuel composition has an influence on combustion behavior. In this study, the influence of liquid single-component fuels on exhaust gas emissions of a gas turbine model combustor for swirl-stabilized spray flames was investigated under atmospheric pressure. The nozzle exhibited a dual-swirl geometry and a prefilming airblast atomizer. The spray was characterized by Phase Doppler Anemometry (PDA) and Mie scattering measurements and the flame CH* chemiluminescence was measured. Six single-component hydrocarbons were chosen: three linear alkanes (n-hexane, n-nonane, n-dodecane), one cyclic alkane (cyclohexane), one branched alkane (iso-octane) and one aromatic hydrocarbon (toluene). Kerosene Jet A-1 was used as a technical reference. Results show minor differences in CO emissions and significant differences in NOx emissions of the various fuels at comparable flow conditions and adiabatic flame temperatures. The measurements indicate a correlation between the nitric oxide emissions and the spray quality.

Full text
Abstract:
Dimethyl Ether (DME) has been known as a ultra clean smokeless fuel for diesel engines for over a decade now. A significant challenge is to ensure full lifetime for the diesel engine injection equipment when handling the low boiling point DME as this fuel has very low viscosity and lubricity. Pressurised lubricity evaluators show that boundary lubrication additives increase DME lubricity significantly but recent work indicate that adequate performance in quasi-boundary lubrication is necessary for reducing the wear effectively in real pumps. In this regime where the pump surfaces are only separated by a few molecular layers fuel molecular structure and viscosity seem to be important properties. Earlier work showed that addition of low lubricity alkanes raised the high lubricity of a boundary lubricant to an even higher level. In the present work the long linear alkane n-hexadecane was added to DME in different proportions. The lubricities of the blends do not show any minimum but reflect the lubricity of pure n-hexadecane. It is not conclusive whether DME is a boundary or a quasi-boundary lubricant but clarifying tests are currently in progress.

Abstract:
This study consists of a non-traditional molecular and stable isotope approach to analyze organic matter (soluble bitumen and produced oil/condensate) from the Montney Formation low-permeability reservoirs, with the purpose of identifying source(s) of hydrocarbons, accumulation history and post accumulation processes. The same approach bases on the distribution of compound classes such as aromatic carotenoids, polycyclic aromatic hydrocarbons (PAHs), bicyclic alkanes, and oxygen-polar compounds. The geochemical screening has been enhanced with performing compound specific isotope analysis (CSIA) of n-alkanes and selected aromatic hydrocarbons. Widely spread PAHs, the presence of molecular indicators of euxinia, and hydrocarbon mixtures identified using CSIA profiles, are some of the key findings from this research, which will improve our understanding of the Montney petroleum system(s).
