DISQUAC predictions on VLE andH^Efor ternary mixtures containing 1‐alkanols and hydrocarbons

Abstract

Thermodynamic properties, vapor‐liquid equilibrium or excess enthalpy, for a set of 13 ternary mixtures including one or two 1‐alkanols and hydrocarbons are studied in the framework of the DISQUAC group contribution model. The study is extended for the binaries involved. The DISQUAC analysis is developed using interchange coefficients available in the literature. No ternary interactions are taken into account.The average relative standard deviations are 0.02 for pressure in the vapor‐liquid equilibria (4 systems); and 0.07 for the excess enthalpy (9 systems).
