ABSTRACT

Isothermal (vapor + liquid) equilibrium data for the binary mixtures of (propylene oxide + ethanol) and (propylene oxide + 1-propanol) were measured using a static apparatus at three different temperatures ranging from (303.15 to 333.15) K at an interval of 15 K. The measured data were correlated using Peng Robinson Stryjek Vera equation of state (PRSV EOS) combined with van der Waals one-fluid mixing rule for the vapor phase and with Wong-Sandler mixing rule involving a non-random two liquid (NRTL) model, universal quasi-chemical (UNIQUAC) model and Wilson model for the liquid phase. The experimental data are in good agreement with the correlation results.
