离子液体在CO2环加成反应中的应用

摘要

As a new type of "green solvent", ionic liquids are widely used in CO2 cycloaddition reaction due to their good thermal stability, low volatility and structural design, etc.This review summarized the research progress on the use of ionic liquids as catalysts for the cycloaddition reaction of CO2 with epoxides to prepare cyclic carbonates.Ionic liquid catalyst is divided into ordinary ionic liquid catalyst and supported ionic liquid catalyst in view of the perspective of reaction phase.The catalytic performances were briefly described.The main existing problems of ionic liquid catalysts were analyzed, and the future prospects were prospected.%离子液体 (ILs) 作为一种新型的"绿色溶剂", 因其具有热稳定性好、挥发性低、结构可设计性等优点被广泛应用在CO2环加成反应中.综述了由ILs催化CO2与环氧化物的环加成反应制备环状碳酸酯的研究进展, 从反应相态的角度将ILs催化剂分为普通ILs催化剂和负载ILs催化剂, 分别阐述了其催化性能.简要分析了ILs催化剂目前存在的主要问题, 并对ILs在CO2环加成反应中的应用进行了展望.
