摘要
以4,4'二羟基联苯,1-溴代十二烷,1,10二溴癸烷,咪唑,N-甲基咪唑为主要原料,采用微波辅助法合成了2种含联苯基团的的咪唑类离子液体:[Cph-ph C-Min]Br和[Cph-ph C-Min-C]Br,并对最优合成条件进行了探究.结果表明,微波功率80 W,反应时间5 min,N-烷基咪唑与溴代烷摩尔比2 1的条件下,两种产物的产率分别为24.4%和33.1%.与传统方法相比,本研究反应条件易于实现,无需惰性气体保护,反应时间由传统的24 h缩短至5 min.并通过红外光谱和1H NMR验证了2种离子液体的结构.
Two imidazole inoic liquids containing biphenyl group [Cph-ph C-Min]Br and [Cph-ph C-Min-C]Br）,were synthesized from 4,4＇-biphenol,1-bromododecane,1,10-dibromodecane,N-methylimidazolium,and imidazole with microwave irradiation and the optimal conditions have been studied.The results showed that the yield of two products is 24. 4% and 33. 1% when N-alkyl imidazole and bromothane molar ratio 2 1 with microwave power is 80 W and reaction time 5 min,respectively.Compared with traditional methods,the reaction conditions in this study are easy to implement without inert gas protection,and the reaction time is shortened from 24 h to 5 min.The structure of ionic liquids containing biphenyl group was verified by IR and1 H NMR.
