Kinetic studies of methylmercaptan production from dimethyl sulfide and H2S

Kinetic regularities of methylmercaptan production from dimethyl sulfide and H2S in the presence of γ-Al2O3 have been studied under gradientless conditions. A stepwise reaction mechanism is suggested implying that the catalyst surface is methoxylated by methyl sulfide and then CH3O groups interact with H2S. The kinetic equation obtained describes fairly well this process on the nonhomogeneous catalyst surface.
