摘要
采用微波辐射法一步合成1-丁基-3-甲基咪唑六氟磷酸([Bmim]PF6)离子液体,产物结构经过IR和1H NMR验证。通过考察各种影响因素对产物的影响得出最佳的反应条件:n(溴代正丁烷)∶n(1-甲基咪唑)∶n(六氟磷酸钾)=1.1∶1∶1.6(摩尔比),70℃以及250 W的微波功率下照射15 min,收率可达到92.7%。
Under ionic liquid was were investigated microwave irradiation, 1-butyl-3-methylimidazolium hexafluorophosphate （ [ Bmim] PF6 ） synthesized by one-step method. All reaction factors affecting The results showed the optimal reaction conditions as follows： the yield of the product the molar ratio of 1-bromobutane, 1-methylimidazole and KPF6 was 1.1 ： 1 ： 1.6, the temperature was 70℃, the power of microwave was 250 W, the time of microwave irradiation was 15 min, the final yield was 92.7%. The structure of the product was confirmed by IR and 1HNMR analysis.
