ABSTRACT
The liquid liquid equilibria for the water + n-pentanoic acid + n-heptane system and the water + n-pentanoic acid + dichloromethane system were determined at 298.2 K. The NRTL and UNIQUAC models were applied to both ternary systems. The interaction parameters obtained from the NRTL model correlated with the equilibrium compositions better than those from the UNIQUAC model.
