Densities, ρ, and molar excess volumes, V E , for binary and ternary systems of (1,4-dioxane, 1-propanol or 2-propanol, and 1,2dichloroethane) were measured over the whole composition range, at T = [288.15, 298.15, 308.15, and 318.15] K, and atmospheric pressure. The density measurements were performed using an Anton Paar vibrating U-tube densimeter. The binary mixtures of 1-propanol or 2-propanol with 1,4-dioxane present positive V E values over the whole composition and working temperature ranges, whereas with 1,2-dichloroethane even negative V E values are observed at higher alcohol mole fraction and at lower temperature. The V E magnitude, for the alkanol containing binary mixtures, increases as the temperature increases and decreases for 1,4-dioxane + 1,2-dichloroethane. The experimental V E data, for all the binary mixtures, were fitted to the Redlich−Kister equation. For all the ternary mixtures, the excess molar volumes are found to be positive and increase with the temperature increase. The experimental ternary V E values were fitted to the Cibulka equation. The capability of the Prigogine−Flory−Patterson theory (PFP model) in predicting excess volume, for binary mixtures, was tested. Comparison of the experimental V E values with the PFP calculations, for all the binary mixtures, at 298.15 K, was graphically presented.
