摘要:

在283.15-333.15 K温度范围内, 测量了质子型离子液体N,N-二甲基乙醇胺丙酸盐(DMEOAP)的密度、粘度及电导率. 讨论了温度对密度、粘度和电导率等物理化学参数的影响. 通过经验和半经验方程得到了该离子液体的热膨胀系数、分子体积、标准摩尔熵及晶格能等热力学性质参数. 由电导率和密度计算出了该离子液体的摩尔电导率. 利用Vogel-Fulcher-Tamman (VFT)方程, 将测量的动力粘度和电导率对温度拟合, 得到了动力粘度和电导率随温度变化方程式.并通过Walden规则, 建立了粘度与摩尔电导率之间的联系.

Abstract:

The density, viscosity, and conductivity of protic ionic liquid (PIL) N,N-dimethylethanolammonium propionate (DMEOAP) were determined in the temperature range of 283.15-333.15 K. The influence of temperature on density, viscosity, and conductivity is discussed. The thermal expansion coefficient, molecular volume, standard molar entropy, and lattice energy of DMEOAP were calculated using empirical and semiempirical equations. The molar conductivity of DMEOAP was determined fromdensity and conductivity data. The temperature dependence of viscosity and conductivity data was fitted using the Vogel-Fulcher-Tammann (VFT) equation. The relationship between molar conductivity and viscosity was determined by the Walden rule.
