Abstract

Изобретение относится к способу получения метилмеркаптана путем взаимодействия метанола с сероводородом в паровой фазе при температуре ниже 350°С в присутствии катализатора, представляющего собой карбонат щелочного металла, нанесенный на оксид алюминия, а также к указанному катализатору, используемому при температуре ниже 350°С. Предлагаемый способ повышает селективность реакции в отношении метилмеркаптана, используемый катализатор более стабилен во времени.
