New method of dimethyl sulfide synthesis

The synthesis of dimethyl sulfide consists in the reaction of dimethyl disulfide with methanol in the presence of solid catalyst, aluminum γ-oxide. The yield of dimethyl sulfide grows with growing temperature, contact time, and content of methanol in the reaction mixture. At 350–400°C, molar ratio methanol-dimethyldisulfide 2.0–2.5, and total conversion of the reagents the yield of dimethyl sulfide reached 95 mol%.
