摘要

在这项工作中,我们测定了1-丙基-3-甲基咪唑溴,[PrMIm]Br在[PrMIm]Br +碳酸乙烯+水的三元混合物中在T =(298.2, 308.2和318.2)K和0.1MPa下的电导率和折射率等热物理性质。对[prim]Br离子液体在碳酸乙烯+水溶剂的混合物中,以质量分数为10、20和30 %的碳酸乙烯(EC),在离子强度为0.0029 ~ 0.2500 mol.kg-1范围内进行了电导测量。用Fuoss-Onsager方程对这些数据进行处理,得到了极限摩尔电导率()和离子结合常数(KA)的值。这些结果用于计算所研究体系的瓦尔登积()和相应的离子结合过程的标准热力学函数,包括吉布斯自由能()、焓()和熵()。此外,在T =(298.2, 308.2和318.2)k时,测量了二元和三元[PrMIm]Br +水+ EC混合物的折射率,计算了折射率偏差(ΔnD),并分别使用Redlich-Kister和Cibulka方程对ΔnD的二元和三元数据进行了关联。同时,利用混合规则将实测折射率与计算值进行了比较。

Conductometric and Refractometric Studies of 1-Propyl-3-methylimidazolium Bromide Ionic Liquid in Water + Ethylene Carbonate Mixtures at T = (298.2, 308.2 and 318.2) K
In this work, we determined thermophysical properties such as electrical conductivity and refractive index for 1-propyl-3-methylimidazolium bromide, [PrMIm]Br in ternary mixtures of [PrMIm]Br + ethylene carbonate + water at T = (298.2, 308.2 and 318.2) K and 0.1MPa. Conductometric measurements were carried out for [PrMIm]Br ionic liquid in ethylene carbonate + water solvent mixture in various composition 10, 20 and 30 mass% of ethylene carbonate (EC) in the ionic strength ranging from 0.0029 to 0.2500 mol.kg-1. These data were treated by Fuoss-Onsager equation, and the values of limiting molar conductivity ( ) and ion association constant (KA) were obtained. These results used to calculate the Walden product ( ) and the corresponding standard thermodynamic functions of ion association process including Gibbs free energy ( ), enthalpy ( ) and entropy ( ) for the investigated system. In addition, refractive indices were measured for the binary and ternary [PrMIm]Br + water + EC mixtures at T = (298.2, 308.2 and 318.2) K. The refractive index deviations (ΔnD) were calculated and the binary and ternary data of ΔnD were correlated using Redlich-Kister and the Cibulka equations, respectively. Also, the measured refractive indices were compared to the calculated values using some mixing rules.
