| 摘 要： | 采用1-溴代己烷和N-甲基咪唑为原料,微波辅助快速合成了溴化1-己基-3-甲基咪唑(HMIM]Br)中间体,此步反应产率可达到95%。通过将中间体和六氟磷酸钾进行离子交换,制备了离子液体1-己基-3-甲基咪唑六氟磷酸盐(HMIM]PF6),产率约为48%。与传统方法相比,反应时间极大地缩短。产物的结构经傅立叶变换红外光谱(FT-IR)、超导脉冲傅立叶变换核磁共振氢谱(1HNMR)和超导脉冲傅立叶变换核磁共振碳谱(13CNMR)确认,纯度经高效液相色谱法(HPLC)分析达到99.0%以上。

| Abstract: | The intermediate 1-hexyl-3-methylimidazolium bromide (HMIM]Br) was synthesized from N-methylimidazolium and 1-hexylbromide under microwave radiation,and 1-hexyl-3-methylimidazolium hexafluorophosphate ( HMIM]PF6) was then prepared using HMIM]Br and KPF6 by anion exchange.Compared with traditional methods,the reaction time required was greatly reduced. The structure of the synthesized product was confirmed by FT-IR,1HNMR and 13CNMR,and the purity of the product was determined to be above 99.0% using high ... |
