Arenothiophenes in oil basic sulfoxides synthesis and oxidation receiving sulfoxides from oil

Abstract

Some of the sulfide compounds were converted to sulfoxides by the action of a 30% solution of hydrogen peroxide on the acid catalyst of a molecule of bicyclic sulfide organic compounds in the paraffin distillate of the oil. The resulting sulfoxides were treated with 70% sulfuric acid and sulfate compounds of sulfoxides were obtained. In order to confirm the composition and structure of these compounds, chemical reactions of the corresponding sulfoxides on the basis of benzothiophene derivatives were carried out.
