室温离子液体1-丁基-3-甲基咪唑六氟磷酸盐的合成研究

Study on the synthesis of room temperature ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate

由1-甲基咪唑和溴代正丁烷合成了中间体溴化1-丁基-3-甲基咪唑,讨论了温度和反应自身放热对此步反应的影响。中间体再经过阴离子交换,得到了标题化合物,收率为92%。产物的结构经IR和1HNMR确认。

The key intermediate, l-butyl-3-methylimidazolium bromide, was synthesized efficiently from 1-methylimidazole and l-bromobutane.The influence of temperature and reaction heat of itself on this reaction was also investigated. After anion exchanging, room temperature ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate was obtained in 92% yield.The structure of final product was confirmed by IR and 1HNMR spectral data.
