CATALYST FOR METHYLMERCAPTANE PREPARATION FROM METHANOL AND HYDROGEN SULFIDE Russian patent published in 2009 - IPC B01J23/30 B01J23/04 B01J21/04 B01J37/20 B01J37/28 C07C319/08 

Abstract RU 2358803 C2

FIELD: chemistry.

SUBSTANCE: invention refers to methylmercaptane synthesis prepared from aluminium oxide, alkali metal wolframate and at least one of ammonium salt containing sulphur or nitrogen with catalyst pH in water suspension 10% being 5.0 - 9.7. The method of methylmercaptanes preparation from methanol and hydrogen sulfide using said catalyst is described also.

EFFECT: enhancing of catalyst activity and selectivity particularly at low hydrogen sulfide/methanol ratios.
