摘　　要：以1-甲基咪唑和氯代正丁烷为原料,合成1-丁基-3-甲基咪唑氯盐离子液体,考察反应条件对产物收率的影响。结果表明,合成1-丁基-3-甲基咪唑氯盐离子液体的最佳条件为:反应温度80℃,反应时间40 h,1-甲基咪唑与氯代正丁烷的摩尔比5∶7。对反应产物进行了红外表征,确定了合成产物即为1-丁基-3-甲基咪唑氯盐离子液体。The synthesis of 1-butyl-3-methylimidazolium chloride was investigated. The effect of the ratio of 1-methylimidazole and n-butyl chloride, reaction time and temperature etc. were discussed. The result showed that the optimum conditions are the molar ratio of 1 -methylimidazole to n-butyl chloride is 5： 7, the reaction temperature is 80 ℃ and the reaction time was 40 h. According to the infrared spectra,the syn- thetic product is 1-butyl-3-methylimidazolium chloride.
