This investigation is a continuation of our previous work on the feasibility of utilizing ultra-high resolution electrospray ionization/ion mobility spectrometry (ESI/IMS) for in situ analysis of biomolecular compounds. The compounds we studied, in this investigation, were glycine, the smallest amino acid and four of its oligomers, namely triglycine, tetraglycine, pentaglycine, and hexaglycine. Experimental effects of drift-gas polarizability on target ions in IMS were explored by utilizing four different drift-gases with differing polarizability values (He, Ar, N2, and CO2). The gas-phase ion radii for all five compounds were calculated from the reduced ion mobilities, K0m, and the effective drift-gas radii employing a simple hard-sphere model. When ion radii were plotted against the polarizabilities of the drift-gases, linear plots with different slopes were produced. This empirical observation indicated that the polarizing of drift-gas can change the calculated ion radii in a linear fashion over a limited range of polarizability values and does not affect all ions equally. This effect can be exploited in order to alter the separation factors between different ions since all ions that yield different slopes can, theoretically, be separated with IMS using different drift-gases. We demonstrated that the separation factor (alpha) is highly dependent on the drift-gas. The maximum separability and, hence, unique identification of target ions was achieved when He and CO2 were used.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model.

Background: Quantitative structure?mobility relationships are proposed to estimate the electrophoretic mobility of diverse sets of analytes in capillary zone electrophoresis using Abraham solvation parameters of analytes, namely the excess molar refraction, polarizability, hydrogen bond acidity, basicity, and molar volume. Multiple linear regression (MLR) as a linear model, adaptive neuro-fuzzy inference system (ANFIS), and artificial neural network (ANN) methods were used to evaluate the nonlinear behavior of the involved parameters. The applicability of the Abraham solvation parameters to the mobility prediction of analytes was studied employing various datasets consisting of organic acids, benzoate derivatives, pyridines, and ammoniums. Method: To evaluate the simulation ability of the proposed models, datasets were subdivided into training and test sets in the ratio of 3:1. To evaluate the goodness of fit of the models, squared correlation coefficients (R2) between experimental and calculated mobilities were calculated. Results: R2values were better than 0.78for all datasets except for organic acids, in which the ANFIS model showed better ability to predict their mobility than that of MLR and ANN. In addition, the accuracy of the models is calculated using mean percentage deviation (MPD) and the overall MPD values for test sets were better than 15% for all models. Conclusion: The results showed the ability of the developed models to predict the electrophoretic mobility of analytes in capillary zone electrophoresis.

Neophylpalladium complexes of the type [Pd(CH2CMe 2Ph)(N-O)(L)], where N-O is picolinate or a related bidentate, monoanionic ligand (6-methylpyridine-2-carboxylate, quinoline-2-carboxylate, 2-pyridylacetate or pyridine-2-sulfonate) and L is pyridine or a pyridine derivative, efficiently catalyze the oxidation of a range of aliphatic, benzylic and allylic alcohols with oxygen, without requiring any additives. A versatile method is described which allows the synthesis of the above-mentioned complexes with a minimum synthetic effort from readily available materials. Comparison of the rates of oxidation of 1-phenylethanol with different catalysts reveals the influence of the structure of the bidentate N-O chelate and the monodentate ligand L on the catalytic performance of these complexes.

Lignocellulosic biomass is considered an abundant and renewable source to produce bio-oils with an objective of its value addition for fuels and chemicals. Upgrading strategies have immensely evolved as a result of ever progressing research in this field. Development of complete analytical protocol for bio-oil characterization at different stages of its production, storage, upgrading and during its use is essential for the purpose of its quality assurance and understanding. This report is aimed at developing a sample preparation procedure for bio-oils involving an extensive liquid-liquid extraction approach. Bio-oil obtained after slow pyrolysis of Jatropha Curcas seed cake was phase separated and subjected to solvent extraction. Various solvents were screened for their extraction capabilities towards available organic compounds of all functional group in the bio-oil. Ethyl acetate, dichloromethane, carbon tetrachloride, diethyl ether, benzene, cyclohexane and hexane were employed for extraction of aqueous phase under similar conditions. Recoveries of compounds containing varying functional groups indicated ethyl acetate and dichloromethane as optimum among all other solvents. During the extraction, partitioning of compounds between bio-oil phase and solvent occurred largely on the basis of polarity. Acidic and basic organic compounds present in the aqueous phase were determined after adjusting the pH of samples followed by dichloromethane extraction. A comprehensive detail of the extracted chemicals and their classification has been provided. The identification was carried out qualitatively with GC-MS and derivatization of polar chemicals was also carried out before analysis. These experiments compare the efficacy of various organic solvents for extracting diverse bio-oil pyrolytic products. The findings are important in ascertaining usefulness of organic solvents towards enrichment of available bio-oil chemical groups. The information may be either utilized for characterization purposes or their monitoring during upgrading process.

A bacterium capable of degrading 2-methylpyridine was isolated by enrichment techniques from subsurface sediments collected from an aquifer located at an industrial site that had been contaminated with pyridine and pyridine derivatives. The isolate, identified as an Arthrobacter sp., was capable of utilizing 2-methylpyridine, 2-ethylpyridine, and 2-hydroxypyridine as primary C, N, and energy sources. The isolate was also able to utilize 2-, 3-, and 4-hydroxybenzoate, gentisic acid, protocatechuic acid and catechol, suggesting that it possesses a number of enzymatic pathways for the degradation of aromatic compounds. Degradation of 2-methylpyridine, 2- ethylpyridine, and 2-hydroxypyridine was accompanied by growth of the isolate and release of ammonium into the medium. Degradation of 2-methylpyridine was accompanied by overproduction of riboflavin. A soluble blue pigment was produced by the isolate during the degradation of 2-hydroxypyridine, and may be related to the diazadiphenoquinones reportedly produced by other Arthrobacter spp. when grown on 2-hydroxypyridine. When provided with 2- methylpyridine, 2-ethylpyridine, and 2-hydroxypyridine simultaneously, 2- hydroxypyridine was rapidly and preferentially degraded; however there was no apparent biodegradation of either 2-methylpyridine or 2-ethylpyridine until after a seven day lag. The data suggest that there are differences between the pathway for 2-hydroxypyridine degradation and the pathway(s) for 2- methylpyridine and 2-ethylpyridine.

The synthesis and characterization of copper(II) benzoates with the apical donors pyridine, 2-CH3-pyridine, 2,4-(CH3)2-pyridine, 2,6-(CH3)2-pyridine, 2-fluoropyridine, 2-chloropyridine, 2-bromopyridine, 3-bromopyridine, 2,5-dibromopyridine, 3,5-dibromopyridine, and aniline, starting from copper (II) benzoate, is reported. Single-crystal X-ray structures of the products with four apical ligands show the usual paddle-wheel structure of copper(II) carboxylates; in the case of aniline no paddle-wheel dicopper(II) benzoate could be isolated. The products of thermal decomposition of the pure copper(II) compounds were analyzed by HPLC, LC-MS, and GCFID, and the expected DOW-phenol products were found in all cases other than that of aniline. This supports the assumption that a paddle-wheel dicopper(II) benzoate is required for the DOW-phenol reaction. Generally, high orthoselectivities (to phenyl benzoate and phenol; the selectivity increases with increasing basicity) are obtained, in good agreement with earlier findings on the role of the base. Small but significant steric effects are observed in the series of methylated pyridine donors and the monohalogenated pyridine donors used as apical ligands; with the two dibromopyridine donors there are large steric effects and the DOW-phenol reaction is partially suppressed. With halogenated pyridine donors as apical ligands, a Cu[I]-catalyzed process occurs, leading to dehalogenation.

An examination of a variety of common nitrogen-containing systems was undertaken to optimize parameters for observation of 1H- 15N long-range correlations. Because of the diversity of coupling constants encountered with 1H-15N correlations, a modified accordion-based sequence was used to provide the best results. Optimization of the values for the accordion delay revealed that a range between 3 and 10 Hz provided the best compromise between detection of weak correlations and loss of signal to T2 processes. Multiple bond correlations were readily detected for each class of compound with the exception of anilines. Correlations within heterocyclic systems revealed some general patterns. In general, stronger correlations were observed from protons to ‘pyrrole-like’ nitrogens than to the ‘pyridine-type’ nitrogens of imidazoles and pyrazoles. Very long-range (four- and five-bond) correlations were routinely observed between methyl groups and the nitrogens of aromatic heterocycles. Copyright
