Modeling the Solubility of 1,1,1,2-Tetrafluoroethane (R134a) in RoomTemperature Ionic Liquids using Generic-van der Waals and Generic-Redlich-Kwong Equations of state

In this paper we have examined modeling of 1,1,1,2-Tetrafluoroethane (R134a) solubility in TenRoom Temperature Ionic Liquids (RTILs) based on Generic-Van der Waals (GVDW) and Generic-Redlich-Kwong (GRK) Equations of state (EOSs) and also have compared deviations with each other.Experimental data represent a high correlation with the Present equation of states. It is also concludedthat the absolute average deviation (AAD%) is less than 1% for each system that illustrates highaccuracy and efficiency of the mentioned Present equation of states. Henry s law constant and some thermodynamic properties such as enthalpy (ΔH? ) and entropy (Δ?? ) in infinite dilution are calculated
