摘　　要：在微波辐射下,由甲基咪唑和溴乙胺氢溴酸盐合成了中间体溴化1-甲基-3-氨乙基咪唑,中间体再在微波辐射下经过阴离子交换,得到功能化离子液体1-甲基-3-氨乙基咪唑四氟硼酸盐。通过1 H-NMR和IR对产物结构进行表征确认,并讨论了微波辐射功率和辐射时间对这两步反应的影响。该方法与常规方法相比,具有反应时间短,收率高的优点。The intermediate, 1-methyl-3-aminoethyl imidazole bromide was synthesized by the reaction of methyl imidazole and bromoethylamine hydrobromide under microwave radiation. The functionalized ionic liquid 1-methyl-3-aminoethyl imidazole tetrafluoroborate was obtained by an anion exchange of the intermediate under microwave radiation. The structure of the product was confirmed by 1H-NMR and IR. The effect of microwave radiation power and time on the two-step reaction was studied. The method has the advantages of shorter reaction time and higher yield in comparison with the conventional method.
