The Peng-Robinson-Stryjek-Vera (PRSV) equation of state (EOS) coupled with a modified two parameter van der Waals one-fluid mixing rule (MvdW1) and the Huron-Vidal-Orbey-Sandler mixing rule incorporating the NRTL equation as a GE model was used for the correlation of excess enthalpy (HE), excess heat capacity (CpE) and the simultaneous correlation of both properties. All calculations with temperature dependent parameters of EOS models were applied to 1,3-dioxolane+n-alkane systems. The correlation of the H E and Cp E data alone with four coefficients and the HE+CpE data with six coefficients of the temperature dependent parameters of the HVOS-NRTL models could be considered as very satisfactory.
