The vapor-liquid equilibria in the seven ternary systems water + toluene + aniline, water + octane + aniline, water + toluene + cyclohexylarnine, water + octane + cyclohexylamine, toluene + aniline + cyclohexylamine, octane + aniline + cyclohexylamine, and water + cyclohexylamme + aniline were determined at 333.15 and 363.15 K at reduced pressure. The experimental results were compared with the predictions of the activity coefficient models UNIQUAC and NRTL and the equation of state proposed by Elliott, Suresh, and Donohue (ESD EOS).
