The reactions of hydrogenolysis of representatives of various classes of organosulfur compounds (hexyl mercaptan, dihexyl sulfide, dihexyl disulfide, thiophene, and concentrates of sulfides isolated from diesel fuel) in the presence of MAlCl4 (M = Li, Na, K) was studied.High degrees of conversion of sulfur-containing compounds in hydrogenolysis reactions are achieved at substantially low temperatures (150-250 deg C).The reactions of elimination of sulfur from organosulfur compounds with the formation of H2S occur with the participation of hydride ions, formed in the process; in this case the solvent performs the function of a proton donor.In liquid conversion products the presence of aromatic hydrocarbons is detected.The scheme of occurence of the coupled reactions occuring in the presence of MAlCl4 is cited.
