Catalysis of Bismuth Complex Salt in Vapor Phase Hydrochlorination of Acetylene
|
Abstract:
A non-merury novel catalyst with bimetallic chlorides and bimetallic phosphates based on SiO2 was prepared by dipping method and used in catalytic hydrochlorination of acetylene to vinyl chloride. The experimental results showed that reaction activity of the catalyst could be promoted obviously by introducing PO43- to it. Bimetallic phosphates of Cu and Bi based on SiO2 behaved the best in testing of catalysis, and its initial reaction activity was 1/3 time of conventional industrial HgCl2/C catalyst. The c...
