摘　　要：二氧化碳是导致温室效应的主要气体,是自然界中来源广泛、价格低廉的碳资源,其有效利用一直备受关注。本文设计合成了Co、Zn、Fe三种salen催化剂,并用于催化二氧化碳与环氧丙烷共聚反应;探究了三种催化剂对共聚反应的催化活性;通过红外光谱分析、元素分析、核磁氢谱对合成配体与催化剂的结构进行了表征,并通过核磁氢谱确认了共聚产物成分。结果表明,Salen Co表现出较高的催化活性,具有潜在的应用价值。Carbon dioxide is the main gas causing the greenhouse effect and is abundant and cheap C1 resource in nature.Its effective utilization has received much concern.The catalysts for copolymerization of CO_2 were mainly researched and which generated cyclic carbonate and the catalytic activity of the Salen Co,Salen Zn,Salen Fe catalysts for copolymerization were explored.The salen ligand and complexes were synthesized and characterized by FT-IR,EA,1H-NMR,and the structure of the product of copolymerization was confirmed by1H-NMR.The results indicated that Salen Co showed higher catalytic activity,it will be the research emphasis and direction in future.
