Correlation of ternary excess molar enthalpies for mixtures containing an alkanol and two active non-associated components using a mole-fraction association model

Abstract

Excess molar enthalpies are reported for methanol + toluene + cyclohexane, measured with an isothermal dilution calorimeter at 25°C. The experimental results have been correlated with a mole-fraction association model having binary and ternary parameters. The workability of the proposed model has been confirmed satisfactorily for many ternary alcohol mixtures.
