Abstract

Methyl mercaptan and by-product thiophene can be obtained from the reaction of CO/H2/H2S mixtures over α-Al 2O3 at 340 °C, and selectivities of methyl mercaptan of �98 can be readily obtained in a sustained reaction. γ-Al 2O3 and Cr2O3 were also found to be active catalysts and gave high selectivities to methyl mercaptan, although these catalysts gave (CH3)2S as by-product rather than thiophene. In the absence of H2S, all the catalysts displayed virtually no catalytic activity.
