1，2－二甲基－3－丁基咪唑硫酸氢盐离子液体的合成及其性质研究

摘要

A functionalized ionic liquid 1, 2 -dimethyl-3-butyl-imidazolium hydrogen sulfate has been synthesized in room temperature .The density, surface tension, viscosity and electrical conductivity of the ionic liquid [mmBim][HSO4 ] have been measured in different temperature .According to experimental results, we estimated the coefficient of thermal expansion , standard entropy and lattice energy of the IL by empirical equa-tions.%　　。介绍了在室温下设计合成的一种功能化离子液体1，2－二甲基－3－丁基咪唑硫酸氢盐离子液体［mmBim］［HSO4］均为在不同温度下测定了该离子液体的密度、表面张力、粘度和电导率等性质，并根据特定的经验方程，估算了该离子液体的热膨胀系数、标准熵和晶格能等性质参数，为该离子液体的预期应用提供了重要的数据参考。
