摘要
介绍了近几十年来离子液体作为吸收剂、催化剂或助剂固定/转化CO2的发展历程及其特点,并阐述了CO2在离子液体中高溶度机制。系统分析了传统离子液体(如咪唑盐型、磺酸盐型、铵盐型、吡咯烷盐型离子液体)和任务专一型离子液体对CO2的吸收性能,评价了CO2与环氧化物、炔丙基醇和胺在离子液体中转化时的诸多优点,并指明了离子液体固定/转化CO2的今后发展方向和发展重点。
In this paper,the latest progress in the fixation and conversion of carbon dioxide （CO2） using ionic hquids as absorbents, catalysts or promoters, and the mechanisms of remarkable solubility are summarized. The absorption performance of conventional ionic liquids （for example, imidazolium-type, sulfonate-type, ammonium salt-type, pyrrolidinium-type） and task- specific ones is systematically investigated, the conversion of CO2 with epoxides, propargyl alcohols and amines in ionic liquids is critically evaluated, and the significant advantages in the fixation and conversion of CO2 using ionic liquids are demonstrated. Furthermore, its development direction and emphases are indicated.
