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.

В везградиентных условиях исследованы кинетические закономерности получения метилмеркаптана из диметилсульфида и H2S в присутствии γ-Al2O3. Предложен стадийный механизм реакции, согласно которому диметилсульфид метоксилирует поверхность катализатора, и далее происходит взаимодействие CH3O-групп с H2S. Получено кинетическое уравнение, удовлетворительно описывающее процесс на неоднородной поверхности катализатора.
