Process for the preparation of methylmercaptan Process for the preparation of methylmercaptan |
摘要 |
Vapour phase prepn. of methyl mercaptan from methanol and hydrogen sulphide uses an alkali carbonate/alumina catalyst at below 350 degrees C. The catalyst is claimed per se. The alkali carbonate is of sodium, cesium or pref. potassium and it is deposited on the alumina in an amt. of 2-20% (pref. 6.4) wt.%. The reaction is carried out at 230-330 (pref. 280-310) degrees C and at a pressure of 8-15 bar. The hydrogen sulphide : methanol molar ratio is 1.5-2.5. The catalyst is dispersed in a system contg. at least 3 reactors. |
