Synthesis of Alkyl Mercaptan by Fixed Bed Catalysis

The synthesis of alkyl mercaptan by fixed bed heterogeneous catalysis was introduced. The possible chemical reactions took place in the substitution reaction for synthesizing alkyl mereaptan with using alkyl alcohol and hydrogen sulfide as raw materials were analyzed. Various kinds of mercaptan were prepared by fixed bed heterogeneous catalysis method, including n-propylmereaptan, i-propylmercaptan, n-butylmercaptan and ndodecylmercaptan whose yields were 92.5%, 65%, 76.6% and over 78% respectively. The preparation conditions for the synthesis of alkyl mercaptan mentioned above were presented, such as reaction temperature, pressure and feeding proportion of raw materials.
