FIELD: catalyst for synthesis of methylmercaptan. SUBSTANCE: method consists in synthesis of methylmercaptan from hydrogen sulfide and methanol. Catalyst consists of active aluminum oxide on which potassium tungstate in the amount of 5-25 mas.% is applied by deposition as promoter. Catalyst is obtained due to impregnation effect by two-stage system at intermediate drying. EFFECT: higher selectivity of catalyst produced by said method as compared with catalyst produced by single-stage method. 5 cl, 3 dwg, 1 tbl, 6 ex
