Abstract

In this study, we have examined the modeling of gas solubility in twenty room temperature ionic liquids based on the van der Waals and generic Redlich–Kwong equations of state and have also compared the obtained deviations with each other. The selected gases are carbon dioxide (R744) and 1,1,1,2-tetrafluoroethane (R134a). Experimental data represent a high correlation with the present equations of state. It is concluded that the absolute average deviation is less than 1% for each system, which illustrates the high accuracy and efficiency of the mentioned equations of state. Henry’s law constant and some thermodynamic properties such as enthalpy \((\Delta {{H}^{\infty }})\) and entropy \((\Delta {{S}^{\infty }})\) in infinite dilution are calculated.

摘要

在这项研究中，我们检查了基于范德华斯和通用Redlich-Kwong状态方程的二十种室温离子液体中气体溶解度的建模，并且还将获得的偏差进行了比较。选择的气体是二氧化碳（R744）和1,1,1,2-四氟乙烷（R134a）。实验数据代表了与当前状态方程的高度相关性。结论是每个系统的绝对平均偏差小于1％，这说明了所提到的状态方程的高精度和高效率。亨利定律常数和一些热力学性质，例如无穷大的焓\（（\ Delta {{H} ^ {\ infty}}）\）和熵\（（\ Delta {{S} ^ {\ infty}}）\）计算稀释度。
