室温离子液体1-丁基-3-甲基咪唑磷酸二丁酯的电导率研究
Study of Electrical Conductivity of Room Temperature Ionic Liquid 1-butyl-3-methylimidazolium Dibutyl Phosphate
【摘要】 利用磷酸三丁酯与N-甲基咪唑在恒温150℃下一步合成了离子液体1-丁基-3-甲基咪唑磷酸二丁酯,考察了其在丙酮,水,DMF,乙酸溶剂中的电导率及摩尔电导率。实验发现该离子液体在不同溶剂中的电导率(κ)相差很大,其顺序为κa(水)>κb(DMF)>κc(丙酮)>κd(乙酸)。在相同温度下,电导率及摩尔电导率随浓度的增大而增大;在相同浓度下,电导率及摩尔电导率随温度的升高而增大。
【Abstract】 A novel room temperature ionic liquid, 1 - butyl - 3 - methylimidazoiium dibutyl phosphate was prepared by the reaction of tributylphosphate with methylimidazole directly at the constant temperature of 150℃. The conductivity and the molar conductivity of the ionic liquid in actone, water, DMF, acetic acid were investigated at different temperatures. The results showed that there were great differences among different solvents, and the order wasκa(water) >κb(DMF) >κc(actone) >κd(acetic acid). At the same temperature, the conductivity and molar conductivity were increasing with the concentration. When the concentration was constant, the conductivity and molar conductivity increased with the temperature.
