Simultaneous correlation of the excess enthalpy and W-shaped excess heat capacity of 1,4-dioxane+n-alkane systems by PRSV-HVOS CEOS
In this work the Peng-Robinson-Stryjek-Vera (PRSV) equation of state coupled with the Huron-Vidal-Orbey-Sandler (HVOS) rule was tested for the correlation of the excess enthalpy (HE) and the excess heat capacity (cpE) alone and simultaneously. The HVOS mixing rule incorporates the NRTL equation as t...

| description | In this work the Peng-Robinson-Stryjek-Vera (PRSV) equation of state coupled with the Huron-Vidal-Orbey-Sandler (HVOS) rule was tested for the correlation of the excess enthalpy (HE) and the excess heat capacity (cpE) alone and simultaneously. The HVOS mixing rule incorporates the NRTL equation as the GE model. All calculations were performed using the linear and reciprocal forms of the temperature dependent parameters of the models. For all the evaluations the 1,4-dioxane+n-alkane systems were chosen having in mind the unusually W-shaped concentration dependence of cpE for these systems. The correlation of the HE and cpE data alone for all the investigated systems using four coefficients and for the simultaneous correlation of HE+cpE data using six coefficients of the temperature dependent parameters of the PRSV-HVOS models could be considered as being very satisfactory. |
