Thermodynamics of associated solutions. Correlation of ternary excess molar enthalpies for aniline + alkanol + benzene or acetone mixtures using the UNIQUAC associated-solution model

Abstract

Ternary excess molar enthalpies are reported for 1-propanol + aniline + acetone at 25°C. The UNIQUAC associated-solution model with ternary parameters is used to correlate ternary excess molar enthalpies for aniline + alkanol + benzene or acetone mixtures. The model gives appreciably smaller deviations between the calculated and experimental results than those obtained using polynomial equations.
