摘　　要：以溴代正丁烷和N-甲基咪唑为原料合成了中间体溴化1-丁基-3-甲基咪唑,以中间体与NaBF4进行复分解反应制备了离子液体1-丁基-3-甲基咪唑四氟硼酸盐.探讨了溶剂、原料摩尔比、反应温度、反应时间对中间体和离子液体产率的影响,确定了最佳合成条件.在此工艺条件下,离子液体的产率可达92%以上.1-Butyl-3-methylimidazolium bromide were synthesized using bromic normal butane and 1-methylimidazole.From intermediates,1-butyl-3-methylimidazolium tetrafluoroborate were prepared by replacement reaction.The effects of solvent,mole ratio,reaction temperature and reaction time upon intermediates and ionic liquids yield were investigated.The best synthetic conditions of intermediates and ionic liquids were discussed.The results indicate that ionic liquids rate of production can reach over 92% in this conditions.
