Abstract
Thermodynamic properties of mixtures such as partial molar volume provide valuable information about the molecular interactions that take place in a liquid solution. Such studies are also fundamental for the test and development of theories and models. This work presents the ability of the Prigogine–Flory–Patterson model to predict partial molar volumes of binary liquid mixtures containing toluene and n-alkanes (C6, C7, C8, C9, C10, C12 and C16) at 298.15K from excess molar volume data. The model was also applied to correlate the partial molar volume data. The results indicated that the model, which has just one adjustable parameter, is able to predict or correlate data of partial molar volume with high accuracy and robustness.
