摘要
以N-甲基咪唑和1-溴代辛烷为原料合成出溴化1-辛基-3-甲基咪唑[OMIM]Br。研究了反应时间、反应温度及N-甲基咪唑与1-溴代辛烷的物质的量比（原料比）对[OMIM]Br收率的影响，产物结构经。HNMR表征。实验确定的最佳工艺条件是：反应时间12h，N-甲基咪唑与1-溴代辛烷物质的量比1：1．3，反应温度80℃，收率为93．32％。
1 - hexyl - 3 - octyllidazolium bromide was syntnesized by reaction of N - octylidazolium with bromohexane and its structure was determined by 1NMR. The effects of reaction conditions such as time, reaction temperature, mole ratio of N - octylimidazole to bromohexane （ material ratio） on the product yield were examined. The resuits showed that the yield 93.32% was under the reaction conditions as follows： reaction temperature, reaction time 12 hours, mole ratio of N -octylimidazole to bromohexanel： 1.3.
