摘 要:“双碳”背景下,利用CO_(2)与环氧化合物为原料制备聚醚碳酸酯多元醇是CO_(2)化工利用的有效途径。高效的催化剂能够促进CO_(2)与环氧化物反应,制备更高性能的聚合物产品。本文详细介绍了近3年CO_(2)与环氧化合物开环共聚催化剂研究的主要进展。文中从非均相催化剂和均相催化剂两个方面,分别对金属羧酸盐、双金属氰化物、金属Salen、金属卟啉以及新型有机催化剂进行归类和综述。低廉的非均相催化剂仍是工业化实验的首选,但如何通过催化剂制备工艺控制活性位点分布,从而控制聚合物产品质量,是未来需要研究的重点。金属Salen催化剂是目前最热门的研究方向,其有机配体结构的多样性赋予多种金属组合配位的可能,期待开发更高效低廉的催化剂。Synthesis of poly(ether carbonate)polyol from CO_(2)and epoxides is an effective way of CO_(2)chemical utilization.Efficient catalysts can promote the reactions of CO_(2)and epoxides to produce highperformance polymer products.This paper summarized the main progress of the catalysts for ring-opening copolymerization of CO_(2)and epoxides in the latest three years.Catalysts of metal carboxylates,double metal cyanides,metal Salen complexes,metalloporphyrin and other novel organic catalysts are classified and reviewed from two aspects of heterogeneous and homogeneous catalysts.Inexpensive heterogeneous catalysts are still preferred for industrial applications,but how to control the distribution of active sites in the catalyst preparation process,thereby controlling the quality of polymer products,is the focus of future research.Metal Salen complexes are the hot research areas at present.The diversity of their organic ligand structures endows a variety of metal combinations.It is expected to develop more efficient and inexpensive catalysts in the near future.
