摘要：

The Stryjek-Vera modification of the Peng-Robinson equation of state with two parameter van der Waals one-fluid mixing rule suggested by Schwartzentruber and Renon (SR) and the Orbey-Sandler modification of the Huron-Vidal mixing rule (HVOS) was applied for simultaneous description of vapor-liquid equilibrium (VLE), excess enthalpy (H-E) and excess heat capacity (c(p)(E)) data (VLE + H-E, H-E + C-p(E) VLE + c(p)(E) and VLE + HE + CpE). The HVOS mixing rule coupled with the NRTL equation using the temperature dependent parameters with six optimized coefficients gave mostly satisfactory results for simultaneous fitting of VLE + HE, VLE + c(p)(E), H-E + C-p(E) and VLE + H-E + c(p)(E) data of the non-ideal binary systems diverse complexity.
