1-Butyl-3-methylimidazolium tetrafluoroborate ionic liquids([bmim]BF4 )was synthesized using N-methyl imidazole and 1-bromobutane as the raw materials through a two-stage method. Effects of reac-tion time,reaction temperature and molar ratios of N-methyl imidazole to 1-butylbromide on the product yield were investigated. And effects of ion-exchanged time and ion-exchanged temperature on the yield were examined. The result showed that the optimum conditions were as follows:reaction temperature was 65 ℃ ,reaction time 16 h and molar ratio of N-methyl imidazole to 1-butylbromide 1: 1. 1,the intermedi-ate yield was 94. 8% . The optimum conditions of targeted product were as follows:ion-exchanged tempera-ture was 65 ℃ and ion-exchanged time 24 h.
