Provided is a production method that enables production of carbonyl sulfide by a gas phase flow method without using a catalyst. The method of producing carbonyl sulfide includes causing electrical discharge of a feedstock gas containing starting substances that include CS.sub.2 and one or more selected from the group consisting of CO.sub.2, CO, O.sub.2, and O.sub.3 while in a continuous flow state and then causing release to outside of an electrical discharge zone.

The invention relates to a process for preparing methyl mercaptan from a mixture of carbon oxide, hydrogen sulfide and hydrogen, in the presence of a catalyst based on molybdenum and potassium supported on zirconia, said catalyst not comprising any promoter.
