摘要
二氧化碳是主要的温室气体,也是最丰富的C1资源.利用二氧化碳与环氧化物共聚生成可生物降解的聚碳酸酯是目前研究的热点之一.就目前的研究情况而言,二氧化碳与环氧化物共聚反应存在的主要问题是催化效率低、催化剂成本高、反应条件苛刻、共聚物产率较低以及催化剂分离复杂等.我们分类综述了二氧化碳与环氧化物共聚的新型催化体系,并探讨了各类催化体系的优缺点,对二氧化碳的资源化利用具有重要的应用价值.
Carbon dioxide is the main greenh dioxide and epoxide to produce biodegradable ouse gas, which is the most abundant resources of Cl. Using carbon polycarbonate is one of the hot spots. In view of the current research situation, the main problems of carbon dioxide and epoxide copolymerization catalytic systems are low catalytic efficiency, high catalyst cost, harsh reaction conditions, low copolymer yield and complicated catalyst separation. This paper summarizes the latest catalytic systems for the copolymerization of carbon dioxide with epoxides in recent years, and studies the advantages and disadvantages of various catalytic systems, which are of great value for the application of carbon dioxide.
