Oxidative Methods for the Study of the Structural Group Composition of Organosulfur Compounds

详细

The composition of the organosulfur compounds of the oil fraction of Arlan oil was studied using a method involving the two-step oxidation of these compounds with 30% hydrogen peroxide in the presence of an acid catalyst at 80° and 100°C. Vacuum distillation of the organosulfur compounds into narrow fractions showed that the sulfoxides obtained by oxidation of the organic sulfur compounds of the oil fraction are thiamono-, thiabi-, and thiatricycloalkanes, aliphatic sulfides, and alkylcycloalkyl sulfides. No aromatic compounds were detected in the sulfoxides. Sulfones in the narrow fractions are mainly represented by thiaindanes, alkylcyclano- and alkylbicyclanobenzthiophenes with long alkyl substituents containing from 10 to 15 carbon atoms.
