摘　　要：CO_2与环氧化合物环加成制备环状碳酸酯是一个具有原子经济性的绿色过程。概述了用于该反应的几种均相和非均相催化剂,如有机碱、季铵盐、季鏻盐和咪唑类离子液体等的最新研究进展,重点阐述了氢键供体(如羟基、氨基)与环氧化物成氢键作用对催化剂活性的影响,总结了几种可能的反应机理,为设计高效催化剂提供依据。对于非均相催化剂,利用功能化的载体负载活性组分来提高催化剂活性和稳定性,同时简化催化剂的回收过程。指出了用于催化合成环状碳酸酯的未来发展方向。Preparation of cyclic carbonates by cyclic addition of CO2and epoxides is a green process with atomic economy. The recent progresses in several kinds of homogeneous and heterogeneous catalysts for this reaction, including organic bases, quaternary ammonium salts, quaternary phosphonium salts, and imidazole ionic liquids, are overviewed with an emphasis on the effects of hydrogen bonding （between hydroxyl/amino group and epoxide） on the activity of catalysts, and several possible reaction mechanisms are summarized to provide the basis for designing an efficient catalyst. For heterogeneous catalysts, functionalized supports are used to support the active components to increase catalyst activity and stability while simplifying catalyst recovery. The future development directions of catalysts for the catalytic synthesis of cyclic carbonate are pointed out.
