Synthesis of methyl mercaptan and thiophene from CO/H2/H 2S using α-Al2O3

Zhang, B., Taylor, Stuart H. ORCID: and Hutchings, Graham John ORCID: 2003. Synthesis of methyl mercaptan and thiophene from CO/H2/H 2S using α-Al2O3. Catalysis Letters 91 (3-4) , pp. 181-183. 10.1023/B:CATL.0000007152.91400.95

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.
