VLE data for CO2 + CH3I system were measured from 283.15 to 323.15 K.This system showed positive deviation from the Raoult's law and no azotrope observance.Experimental data were well correlated with PR-EoS using WS-mixing rule and UMR.Binary parameters (kij) do not show temperature dependency.
Isothermal vaporliquid equilibrium data for the binary system carbon dioxide + methyl iodide were measured at temperatures from 283.15 to 323.15 K at 10 K intervals. Data in the two-phase region were measured by using a circulation-type equilibrium apparatus and gas chromatography. This binary mixture system showed positive deviation from the Raoult's law and no azotrope observance. The experimental data were correlated with the PengRobinson equation of state (PR-EoS) using the WongSandler (WS) mixing rule, which was combined with the nonrandom two-liquid (NRTL) excess Gibbs free energy model and PengRobinson equation of state (PR-EoS) using the Universal mixing rule (UMR) as well as with the UNIQUAC model. The calculated results with this combination of equations show positive agreement with experimental data taken within this study.
