摘　　要：离子液体作为一种新型绿色环保介质,由于其结构可设计、稳定性高以及催化活性高等优点,使其在CO_2环加成反应的催化方面应用前景广阔。本文综述了近年来离子液体催化CO_2与环氧化物的环加成反应制备环状碳酸酯的研究进展。传统离子液体包括咪唑类、吡啶类、季铵盐季盐等离子液体,而功能化离子液体包括羟基功能化、羧基功能化等离子液体。与传统离子液体相比,功能化离子液体具有更好的催化活性。无机或有机材料负载的非均相离子液体催化剂报道较多,载体包括SiO_2、氧化石墨烯、聚合物等。非均相催化剂具备易分离、可在固定反应器中连续反应等优点,更适应工业化生产。指出了CO_2与环氧化合物反应制备环状碳酸酯过程中出现的催化剂活性低、反应条件苛刻等关键问题,因此寻求高选择性合成环状碳酸酯的环境友好的新型高效催化剂具有重要的学术意义和实用价值。As a novel environment friendly media,ionic liquids(ILs)have shown advantages in the catalysis of this cycloaddition reaction due to their structure designability,high stability,and high catalytic activity,etc.This review was mainly focus on the latest progress on the use of ILs as catalysts for the cycloaddition of CO2with epoxides.The conventional ILs contained imidazolium,pyridine,quaternary ammonium salt,quaternary phosphonium salts and other ILs.The functionalized ILs included hydroxyl-functionalized,carboxyl-functionalized and other ILs.Compared with conventional ILs,functionalized ILs had much better catalytic performance.A series of inorganic or organic support immobilizing ILs catalysts had been developed.Their supports included mesoporous silica,graphene oxide,polymers,etc.The chemical industry has always preferred to use a heterogeneous catalyst due to the ease of separation and the ability to use in a fixed-bed reactor.How to overcome the disadvantages of low activities,difficulties in separation and tough reaction conditions is a key issue.It is of great academic significance and practical value to pursue the new and efficient catalyst for high selectivity synthesis of cyclic carbonates.
