摘要:制备并研究了溴代1-丁基-3-甲基咪唑([bminm]Br)、[bmim]Br-AlCl3、[bmim]Br-FeCl3离子液体[bmim]Br-AlCl3、[bmim]Br-FeCl3在不同的溶剂水、乙醇、乙酸中的电导率,发现离子液体在不同的溶剂中的电导率相差很大,其顺序为κa(水作溶剂)>κb(乙醇作溶剂)>κc(乙酸作溶剂).相同温度下离子液体的电导率随浓度的增大而增大,相同浓度下电导率随温度的升高而增大,且在同温同浓度下水为溶剂时κ[bmim]Br-FeCl3<κ[bmim]Br-AlCl3,乙醇、乙酸为溶剂时结果为κ[bmim]Br-FeCl3>κ[bmim]Br-AlCl3.

Abstract: This paper focuses on the preparation of several RTLs including 1-ethyl-3-butyl-imildazolium bromine([bmim]Br),[bmim]Br-AlCl3,[bmim]Br-FeCl3,and the electric conductivity of [bmim]Br-AlCl3,and [bmim]Br-FeCl3 in different solvents of water,ethanol,acetic acid.RTLs  have  different electric conductivity in different solvents:the largest is in water,next in ethanol,and the last in acetic acid.Under the condition of the same temperature,the higher  concentration,the larger electric conductivity is.Under the condition of the ame concentration,the higher  temperature is,the larger electric conductivity is.What is interesting is that,under the condition of the same concentration and temperature,when water as the solvent,the electric conductivities of [bmim]Br-FeCl3 is larger than that of [bmim]Br-AlCl3.But when ethanol or acetic acid as the solvent,it has contrary result.

Key words: room temperature ionic liquids, electric conductivity, [bmim]Br-AlCl3, [bmim]Br-FeCl3
