摘　　要：设计了无溶剂一锅法合成1-丁基-3-甲基咪唑四氟硼酸盐和1-丁基-3-甲基咪唑六氟磷酸盐室温离子液体的新的合成路线,反应原料在80℃下搅拌反应3 h,分离产率分别为97.8%和92.9%。用IR1、HNMR1、3CNMR对离子液体的结构进行了表征,热重分析法测试了其热稳定性能分别为340℃和360℃,探索了反应温度和反应时间对产率的影响。Room-temperature ionic liquids 1-butyl-3-methyl-imidazolium hexafluorophosphate （ BmimPF6 ）, 1-butyl-3-methyl-imidazolium tetrafluoroborate （ BmimBF4 ）, were prepared in a reactor free of any solvents or any other medium at 80 ℃ upon stirring for 3 h to give excellent yields of 97.8 % and 92.9 %, respectively. Their structures were characterized by IR, ^1HNMR and 13CNMR,and their thermal stability performance was determined by thermal gravimetric analyses. The influence of reaction temperature and reaction time on the product yields was also explored.
