Excess molar enthalpies of aniline-methanol-benzene mixtures were measured with an isothermal dilution calorimeter at 25-degrees-C. Experimental results for three binary mixtures constituting the ternary mixture are well correlated by use of the UNIQUAC associated-solution model. The ternary experimental results are in close agreement with predicted values obtained from the model having binary parameters. The model is able to satisfactorily predict ternary liquid-liquid equilibria for aniline-methanol-n-hexane and aniline-methanol-n-heptane mixtures using binary information.
