Application of the MvdW1 and HVOS-NRTL mixing rules to the simultaneous correlation of excess enthalpies and W-shaped excess heat capacities data of 1,3-dioxolane plus n-alkane systems

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 G(E) model was used for the correlation of excess enthalpy (H-E, excess heat capacity (C-p(E)) 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 C-p(E) data alone with four coefficients and the H-E+C-p(E) data with six coefficients of the temperature dependent parameters of the HVOS-NRTL models could be considered as very satisfactory.
