离子液体作为一种新型的溶剂，具有许多独特的性质。目前对离子液体的研究主 要集中在新型离子液体的合成、物理和化学性质的表征及作为溶剂和电解质的应用等方面。吡咯烷酮是一种常规溶剂，具有低毒性和优异的溶解能力。本文将吡咯烷酮基团引入离子液体的结构中，获得3种新型的含吡咯烷酮结构的离子液体。通过季胺化反应合成离子液体，用N-甲基吡咯烷和乙酰氯合成N-乙酰基-N-甲基吡咯烷氯盐，用N-甲基吡咯烷和N- 溴乙基-2-吡咯烷酮合成的N-甲基-N-2-(2-氧吡咯烷基)乙基吡咯烷溴盐，用N-甲基咪唑和N-溴乙基-2-吡咯烷酮合成的1-甲基-3-(2- (2-氧吡咯烷基)乙基)-咪唑溴盐。

As a new solvent, ionic liquid has. many unique properties. Many researches on ionic liquids are mainly concentrated on the synthesis of new ionic liquids, characterization of the physical and chemical properties and their uses as solvent and electrolyte and so on. Pyrrolidone is a conventional solvent with low toxicity and excellent solubility. Thus, three novel ionic liquids with pyrrolidone group were synthesized. Through quatemization reaction of one step, N-acetyl-N-methylpyrrolidine chloride, l-methyl-3-(2-(2-oxypyrrolidine)ethyl-imidazolium bromide and N-methyl-N-(2-(2-oxypyrrolidine)ethyl- pyrrolidine bromide were obtained.
