FIELD: industrial organic synthesis.
SUBSTANCE: catalyst is prepared by impregnating alumina with cobalt chloride solution followed by drying and activation, the latter being effected by treating catalyst first with hydrogen sulfide/hydrogen mixture at 380-420оС and then with hydrogen at 200-260оС. Invention also provides catalyst for production methylmercaptan through hydrogenolysis of dimethyl sulfide containing 8.0-15.0% cobalt sulfide applied onto alumina treated by above-indicated method. Process is carried out at dimethyl sulfide supply velocity 13.4 to 128.7 mole/h per 1 g catalyst.
EFFECT: increased methylmercaptan production productivity.
