摘要
室温离子液体作为一种相对友好的溶剂和催化剂体系正在被人们认识和接受。室温离子液体作为反应介质或催化剂具有更宽的液态范围和几乎可以忽略的蒸汽压,并且可以重复使用,这在环境问题日益引起人们关注的今天显得尤为重要。室温离子液体作为反应介质,可以促进反应,它本身也可以作为催化剂,特别是氯铝酸离子液体,对某些反应表现出比传统无机酸更好的催化活性;室温离子液体具有良好的溶解性,可以用做萃取剂,在一些均相反应过程中,由于室温离子液体的加入,可以构成两相体系,有利于产物的分离。作为一类绿色、新型的溶剂和催化剂,室温离子液体具有广泛的应用前景。
Room temperature ionic liquids is more and more recognized and accepted as a kind of novel green solvents and catalysts with great application potential in electrochemistry, catalysis, synthesis and separation for their special physical and chemistry properties. In comparison with the volatile organic solvents now widely used, room temperature ionic liquids as solvents possess wider liquid range and neglectable vapor pressure as well as good reusability, which is very important for today when environment problem is more and more cared by people. Room temperature ionic liquids can accelerate reaction rate as reaction medium. Being used as catalysts, especially chloroaluminate ionic liquids, room temperature ionic liquids show better reaction activity than that of traditional inorganic acids. Room temperature ionic liquids can be used as extract agent. In some homogeneous reaction, because of the addition of room temperature ionic liquids, the reaction system can be separated into two phases, which are good to the separation of the product. In a word, room temperature ionic liquids have wide promising application as a kind of novel green solvents and catalysts.
