Catalyst in Acetylene Carbonylation: From Homogeneous to Heterogeneous

The dicarbonylation of acetylene small molecule. produced based on non.petroleum routes. can produce a large number of high value.added chemicals. which is of great significance in the environmental treatment of CO gas emissions and the chemicals application. The artide mainly reviews the advances in research on the catalyst in acetylene carbonylation from homogeneous to heterogeneous. and summarize the effects of catalyst types and additives on the acetylene mono. / bi.carbonylation reaction activity. Based on the analysis of the reaction mechanism. this article introduces the design ideas for the preparation of high.efficiency catalysts by adjusting the structural sensitivity factors(size effect and morphology effect). Thus the method for controllable preparation of the micro.nano structure of the heterogeneous catalyst and the structure.activity relationship are further reviewed. with a view to provide guidance for the design of a heterogeneous catalytic system for efficient acetylene carbonylation in the future.
