Oxidation mechanism of dibenzothiophene compounds: A computational study

The potential energy surfaces of the oxidation of three model heterocyclic organic sulfides dibenzothiophene (DBT), 4-methylbenzothiophene (MDBT) and 4,6-dimethyldibenzothiophene (2MDBT) were examined using HCO3H as oxidants adopting MP2, omegaB97X-D, M06-2X and B3LYP methods at 6-311+G (d,p) level. The stationary points on the potential energy surfaces for the first and second oxidation reaction were fully optimized and characterized. The natural orbital population analysis (NPA) was also performed to understand the charge distribution. The calculated results may contribute to understanding the reaction mechanism of the ODS of refractory DBT sulfides.

A liquid chromatography?atmospheric pressure photoionization tandem mass spectrometric method for the determination of organosulfur compounds in petroleum asphalt cements

We present a sensitive liquid chromatography?atmospheric pressure photoionization tandem mass spectrometric (UHPLC-APPI-MS/MS) method for the determination of selected organosulfur compounds in Brazilian asphalt cements. It was possible to detect 14 organosulfur compounds of different classes where sulfoxides and sulfones presented higher sensibility in ionization than thiophenes and aromatic sulfides. A dopant-assisted APPI method was also tested, however, when chromatographic flow rate was optimized a decrease in signal was observed for all compounds. PAHs were tested and ruled out as possible interfering compounds and the matrix effect of asphalt cements was within an acceptable range for the quantification of organosulfur compounds. The proposed method was found to have satisfactory linearity and accuracy with recoveries between 83.85 and 110.28% for thianaphthene and 3-methylbenzothiophene, respectively. Therefore, the method allowed the characterization of organosulfur compounds in Brazilian asphalt cements and demonstrated changes in the amount quantified in asphaltenic and maltenic fractions after the RTFOT?+?SUNTEST aging process.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. category: benzothiophene. Introducing a new discovery about 14315-11-8, Name is 4-Methylbenzo[b]thiophene

A method for measuring 1-octanol-water partition coefficients.

A new direct method to determine the 1-octanol-water partition coefficients (Kow, expressed as log Kow) was tested. A dialysis tubing was used to separate water from the octanol phase containing the analyte (naphthalene, aniline, benzo(b)thiopene, etc.), avoiding the frequently encountered problem of emulsions. Different tubings with molecular weight cutoffs of 2000-12,000 mol wt were equally suitable. The analyte concentrations were determined by LC, allowing compounds to be measured in impure samples. The correlation coefficient was 0.998 for log Kow between experimental and theoretical data. The method quickly determines log Kow without a great hardware expense. A >90% savings in equilibration time can be easily achieved by using ultrasonic agitation. The method is experimentally straightforward.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: benzothiophene, you can also check out more blogs about14315-11-8

Abiotic oxidation of petroleum bitumens under natural conditions

Five series of crude oil samples exposed to atmospheric conditions have been analysed at the molecular level, each series comprising several samples originating from the same crude oil but altered to different extents. The aim of our investigation was to compare the specific impact of abiotic oxidation to other alteration processes such as biodegradation, evaporation and water washing. Bulk analyses revealed that increasing alteration is accompanied by an increase in oxygen content which parallels a relative increase of the proportions, as well as of the molecular weights of the macromolecular constituents of the bitumens. Gas chromatographic-mass spectrometric analyses of polar fractions showed the presence of oxygen-containing compounds (steroid ketones, benzothiophenic acids and sulfones) which result from oxidation of petroleum lipids. The hypothesis that part of these oxygenated compounds results from abiotic oxidation processes rather than from biodegradation is supported, notably, by the fact that oxygen incorporation generally occurred without any diastereomeric discrimination. This is also supported by simulation experiments performed on petroleum lipids, which showed that abiotic oxidation induces cleavage reactions affecting C-C and C-S bonds which may intervene in the transformation of geomacromolecules in the environment by degradation (‘depolymerization’). Thus abiotic oxidation may play a major role in the fate of petroleum pollutants in the environment by transforming lipidic organic matter from petroleum into more water soluble and, therefore, more biodegradable constituents. However, these can be more toxic to the environment as the water-soluble fraction may be easily taken up by biota. (C) 2000 Elsevier Science Ltd.
