以金属氧化物负载的碘化钾为催化剂对工氧化碳与环氧丙烷环加成反应进行了研究，考察了反应条件的影响。结果表明，该催化剂是合成碳酸丙烯酯的高效催化剂。基于载体的性质对催化反应机理进行了初步探讨。
The addition reaction of carbon dioxide with propylene oxide was studied by using potassium iodide supported on metal oxide as catalyst. The effects of reaction conditions were investigated. The results show that the catalyst is an efficient catalyst for the synthesis of propylene carbonate. The catalytic reaction mechanism was preliminarily discussed based on the nature of the carrier.
