摘要
以N-甲基咪唑和1-溴代正丁烷为原料合成1-丁基-3-甲基咪唑溴盐[Bmim]Br，研究了反应时间、反应温度、N-甲基咪唑与1一溴代正丁烷的摩尔比及溶剂对[Bmim]Br收率的影响，产物结构通过。HNMR及FT—IR表征。实验结果表明，在反应温度60℃、反应时间24h、N-甲基咪唑与1-溴代正丁烷的摩尔比1：1．2时，收率为91．93％。
1 -Butyl -3-methylimidazolitun bromide [ Bmim ] Br as intermediate of ionic liquid was synthesized using N- methylimidazole and 1-butylbromide as raw materials. The effects of reaction conditions such as reaction time, reaction temperature, molar ratio of N - methyl imidazole to 1 -butylbromide, and solvents on the product yield were examined. The product was characterized using 1H NMR and FT - IR. The result showed that the yield was 91.93 % under the reaction conditions as follows ： reaction temperature 60 ℃, reaction time 24 hours, molar ratio of N- methylimidazole to 1-butylbromide 1 ： 1.2.
