摘要:

一氧化碳(CO)作为一种有害气体,同时是一种宝贵的C1资源。因此,CO的捕集转化是一个重要的化工过程。离子液体因其独特性质已被广泛应用于气体捕集及转化领域。其一,离子液体作为反应介质,促进一氧化碳(CO)转化。其二,具有功能位点的离子液体基吸收剂可以提高CO捕集容量,促进CO转化。其三,离子液体作为催化剂或助催化剂,促进CO转化。本文从离子液体在CO转化中的3种用途(反应介质、吸收剂、催化剂/助催化剂)出发并对适宜的转化反应进行规律性分类总结,综述了离子液体、离子液体基混合溶剂、离子液体基杂化材料强化CO转化的研究进展。离子液体强化的CO转化反应包括酰化、酯化、开环加成、烯烃加成、聚合等。系统地总结了应用于CO转化的离子液体的结构,分析了离子液体基混合溶剂和离子液体基杂化材料在CO转化中的作用机理、影响因素等,最后提出离子液体强化CO转化存在的问题及未来趋势。

Abstract:

Carbon monoxide (CO) is not only harmful to human health but also detrimental to catalysts in proton-exchange-membrane fuel cells as an impurity gas in H2, which is generated simultaneously by steam reforming of natural gas/coal gasification. On the other hand, pure CO is a resource and can be transferred to value-added chemicals. Therefore, CO capture and conversion is an important and sustainable process. Recently, ionic liquids (ILs) have been widely used in the field of gas capture and conversion due to their unique properties, including low vapor pressure, high thermal and chemical stability, high solubility, and tunable structure and properties. Firstly, ILs serve as good reaction media to promote the complete reaction of CO reaction systems. Secondly, ILs, especially functional IL-based green solvents, serve as efficient absorbents to promote the conversion of CO. Thirdly, functional ILs serve as catalysts for catalytic conversion of CO. Therefore, the research progress of ILs, IL-based mixed solvents and IL-based hybrid materials to enhance CO conversion in recent years was reviewed from the aspects of IL-based reaction media, absorbents and catalysts. IL-enhanced CO conversion reactions include acylation, esterification, cycloaddition, olefin addition, polymerization, etc. The structure of ILs was systematically summarized, and the mechanism and influencing factors in CO conversion were analyzed. Finally, the problems and future trends in the CO conversion via ILs intensification were proposed.

Key words: ionic liquids, carbon monoxide, chemical reaction, reactivity, carbonylation, intensification
