离子液体是一类新型的催化CO_2环加成反应的催化剂,因其具有结构可设计性、催化活性高、绿色高效等优点而被广泛应用于催化合成环状碳酸酯.本文主要综述了近几年来各种常规型离子液体及功能化离子液体对CO_2和环氧化合物反应的催化性能的研究进展,其中常规型离子液体主要有咪唑类、季铵盐、季鏻盐、吡啶类等离子液体,而功能化离子液体包括氨基功能化、羟基功能化、羧基功能化、氨基酸类等离子液体.同时对各类离子液体催化CO_2与环氧化合物合成环状碳酸酯的研究中存在的问题进行了分析,并对其应用前景进行了展望.
As a kind of novel catalyst on the cycloaddition reaction of CO2,ionic liquid is widely used in catalyzing reaction of CO2 and epoxides to form cyclic carbonates for the devisable of structure,highly catalytic activity,green and highly efficient.In this paper we mainly reviewed the catalytic performance of various conventional type ionic liquids and functionalized ionic liquids that catalyzed the reaction of CO2 and epoxides to form cyclic carbonates in recent years.The conventional type ionic liquids mainly included imidazolium,quaternary ammonium salt,quaternary phosphonium salt,pyridine and other ionic liquids,and the functionalized ionic liquids included amino-functionalized,hydroxy-functionalized,carboxyl-functionalized,amino acids-functionalized and other ionic liquids.In addition,the problems existing in the synthesis of cyclic carbonates from CO2 and epoxides catalyzed by ionic liquids were analyzed,and the prospect of its application would be expected.
