The possible chemical reaction of alkanethiol with alkyl alcohol and hydrogen sulfide as raw materials was analyzed. A series of alkyl mercaptans were synthesized by fixed bed heterogeneous catalysis. The yield of n-propanethiol was 92.5%, the yield of isopropyl mercaptan was 65%, the yield of n-butyl mercaptan was 76.6% Dialkyl mercaptan yields more than 78%. The preparation conditions of reaction temperature, reaction pressure, feed ratio of raw materials and the like of the above alkyl mercaptan are introduced.
