Abstract: The structure and properties of catalysts for the hydrochlorination of acetylene with different mental salts and their combinations as well as their catalytic performances are summarized and discussed. According to the difference of complexing power between different mental salts，the possible catalytic reaction mechanisms are analyzed. Also，in both heterogeneous and homogeneous phases，the researches on nonmercuric catalysts for the hydrochlorination of acetylene are all reviewed，especially，the components，catalytic mechanism，deactivation and reactivation of gold-based catalysts. The reaction system，which solvent are organics or ionic liquid，is briefly discussed. In the aspect of components，solvents and carriers，some development directions of different nonmercuric catalyst reaction systems are also prospected.

Key words: hydrochlorination of acetylene, nonmercuric catalysts, vinyl chloride
