利用硫酸二甲酯分别与N-甲基及N-丁基咪唑在室温下反应,一步合成了离子液体1-甲基-3-甲基咪唑硫酸甲酯和1-丁基-3-甲基咪唑硫酸甲酯,测定了在不同温度下离子液体的电导率。结果表明:随着温度的升高,离子液体的电导率迅速增加;同时电导率与温度的变化关系符合多项式方程和Vogel-Tammann-Fulcher(VTF)方程。
The methyl ester of 1-methyl-3-methylimidazolium methyl sulfate and 1-butyl-3-methyl group were synthesized in one step by dimethyl sulfate and N-methyl and N-butylimidazole respectively. Imidazole methyl sulfate, measured at different temperatures ionic liquids conductivity. The results show that the conductivity of ionic liquids increases rapidly with the increase of temperature, and the relationship between conductivity and temperature follows the polynomial equation and Vogel-Tammann-Fulcher (VTF) equation.
