Structure and chemical composition of hydrocarbons from semicoking tar of lignites from the near-Moscow fields

Hydrocarbons from semicoking tar of lignites from the near-Moscow fields we re separated by preparative thin-layer chromatography under the optimal con ditions, and the molecular and hypothetical structural formulas of the comp onents were determined. A genetic relationship between the components and t he initial biological material was revealed. A contribution of "primary" hy drocarbons to formation of the qualitative composition of tars obtained by high-temperature processing of lignites was demonstrated.
