Composition of Compounds Bounded via Sulfide and Ether Bridges in Oils of the Organic Matter of Oil Shale of the Dmitrievskoye Field

The method of selective chemical destruction reveals that the compounds linked to each other or to other structural fragments via ether and sulfide bridges are present in addition to the components in molecular form in the oil of the organic matter of oil shale from the Dmitrievskoye field. It is shown using chromatography-mass spectrometry that "sulfur-bound" and 'ether-bound' saturated and polycycloaromatic hydrocarbons are represented by n-alkanes, hopanes, naphthalenes, biphenyls, phenanthrenes, phenylnaphthalenes, fluorenes, fluorantenes, pyrenes and benzo[c]phenanthrene, perylenes and benzo[e]pyrenes. Unsubstituted structures, namely naphthalene, fluorene, triphenylene, and indeno[1,2,3-cd]fluorantene are only linked through a functional C-S group. The results of the study expand the understanding of the composition of the organic matter of oil shales. They are important for the choice of methods for their processing in order to obtain chemically useful components based on oil shale material, including motor fuels.
