Gamma-alumi na has proved to serve as an effective and durable catalyst for the reaction between hydrogen sulfide and methyl alcohol. No change in crystalline structure was observed in the used catalyst by the X-ray diffraction tests. The reacton velocity was extremelyhigh and thus was affected to a great extent by the particle size of the catalyst. When alumina was used as catalyst, rough chemical equilibrium seemed to be attained between methyl mercaptan and dimethyl sulfide. With cadmium sulf ide-alumina catalyst, the product mixture was rich in methyl mercaptan than when alumina was used. Aalumina-thoria catalyst was as active as alumina, and silica was less activ.
