Synthesis of methylmercaptane in the presence of base catalysts

Interaction of methanol with H₂S has been studied at 360–500°C in the presence of Al₂O₃ promoted by alkaline metal compounds. As found, catalysts, obtained via promoting Al₂O₃ by carbonate, and potassium or sodium hydroxide, are more basic in relation to tung-state samples. The total catalytic activity increased, while the selectivity toward methylmercaptane decreased with increasing surface basicity.
