在微波辐射下，1－甲基咪唑分别与有机卤盐(1－溴丙烷、1－溴丁烷、1－溴己烷)在80 ℃回流加热10 min，可制得咪唑类离子液体的中间体溴代1－丁基－3－甲基咪唑（［BMIm］Br）、溴代1－丙基－3－甲基咪唑（［PMIm］Br）、溴代1－己基－3－甲基咪唑（［C6MIm］Br），进一步与HPF6在室温搅拌反应4 h，制得憎水性的咪唑类离子液体［BMIm］PF6，［PMIm］PF6和［C6MIm］PF6。对这3种离子液体及其在不同有机溶剂如丙酮、甲醇、乙酸乙酯中的电导率进行测定，发现离子液体的电导率受咪

By microwave irradiation, the intermediate compounds of imidazolium ionic liquids, 1-Butyl-3-methylimidazolium bromize([BMIm]Br), 1-propyl-3-methylimidazolium bromize([PMIm]Br), 1-hexyl-3-methylimidazolium bromize ([C6MIm]Br) were synthesized from 1-methylimidazole and organic halide (1-bromopropane,1-bromobutane,1-bromohexane) separately under reflux heating at 80 ℃. Each of them reacted separately with HPF6 for 4 hours at room temperature to get hydrophobic imidazolium ionic liquids:1-butyl-3-methyl-imidazolium hexafluorophosphate([BMIm]PF6) and 1-propyl-3-methyl-imidazolium hexafluorophosphate([PMIm]PF6),1-Hexane-3-methyl-imidazolium hexafluorophosphate([C6MIm]PF6). By measuring the conductivities of these ionic liquids and them in the different solvents, i.e. acetone, carbinol and acetic ether, it was found that the conductivity was affected by the kinds of solvents, temperature, concentration and substituent in imidazole. The longer the chain of the substituent was, the bigger the bulk was and the smaller the conductivity of the ionic liquid was. The higher the temperature or the stronger the concentration was, the bigger the conductivity was.
