    Abstract:

    As an important organic intermediate of chemical industry, ethyl mercaptan is widely used in medicine,industry, agriculture and other fields. For the solid acid catalyst for the synthesis of ethyl mercaptan by catalytic addition of ethylene and hydrogen sulfide, the properties, modification methods and the mechanism of ethylene sulfidation reaction were discussed. The analysis indicates that the acid sites are the active center of ethylene sulfidation to form ethyl mercaptan. The balance between the strong acid site concentration and weak acid site concentration determines the stability of solid acid catalyst. For modified alumina and metal sulfide catalysts, the interaction between the modified metal and the support is an important factor affecting the reaction activity.
