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.
