FIELD: chemistry.
SUBSTANCE: present invention relates to a continuous method of producing methylmercaptan which is a valuable organic synthesis intermediate product. The proposed method involves obtaining methylmercaptan through contact of a thoroughly mixed mixture of oxides of carbon, sulphur or hydrogen sulphide and hydrogen at high temperature and pressure in the presence of a moulded solid catalyst which contains K2MoO4 as an active component, an active promoter, where the active promoter is a mixture of oxides or a mixture of sulphides or a mixture of sulphides and oxides of metals selected from a group consisting of iron, cobalt, nickel, lanthanum, cerium and manganese and optionally a carrier.
EFFECT: preparation of a new catalyst for obtaining methylmercaptan and a method which uses this catalyst, which increases methylmercaptan output.
