Application of ERAS-model and Prigogine-Flory-Patterson theory to excess molar volumes for ternary mixtures of (2-chlorobutane + butylacetate + isobutanol) at T = 298.15 K

► Density of ternary and three binary mixtures of (2-chlorobutane + butylacetate + isobutanol) determined. ► Excess molar volume, partial molar volume and apparent molar volume were calculated. ► Excess molar volume was correlated as a function of mole fraction by using the Redlich-Kister and Cibulka equation for all mixtures. ► The experimental results have been used to test the applicability of the ERAS-model and PFP theory.
