摘　　要： 叙述了离子液体的类型和特点,阐明了离子液体是一种安全绿色环保的液体,是当代化学的研究热点之一。由N-甲基咪唑和溴代正丁烷合成了中间体溴化1-正丁基-3-甲基咪唑,又利用中间体进一步合成了离子液体1-正丁基-3-甲基咪唑四氟硼酸盐和1-正丁基-3甲基六氟磷酸盐,并分别对这三种离子液体做了红外光谱分析。简单绍了离子液体在生物技术中物质的分离和纯化,介绍了离子液体在碱金属和碱土金属、稀土金属和锕系等金属离子萃取方面的应用。表明离子液体有着广阔的发展前景。 The types and characteristics of ionic liquids were described, which was a safe and green liquid and one of the hot contemporary of chemistry. The key intermediate 1 -butyl- 3 -methylimidazolium bromide was synthesized efficiently from 1 - methylimidazole and 1 - bromobutane. Using of the intermediates for further synthesis of the ionic liquid 1 - butyl - 3 - methylimidazolium tetratluoroborate and 1 - butyl - 3 - methyl hexafluorophosphate, and ionic liquids were separately made of the IR. The ionic liquids in the separation and purification in biotechnology, the application of extraction in the alkali metals and alkaline earth metals, and rare earth and actinide metal etc. were introduced. It showed that the ionic liquids had broad prospects for development.
