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-phC-Min]Br和 [Cph-phC-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。

Abstract: Two imidazole inoic liquids containing biphenyl group [Cph-phC-Min]Br and [Cph-phC-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 and 1H NMR.
