Ternary Liquid−Liquid(−Liquid) Equilibria of Aniline + Cyclohexylamine + Water, Aniline + Cyclohexylamine + Octane, Aniline + Water + Toluene, and Aniline + Water + Octane

Four ternary liquid−liquid(−liquid) equilibria in the systems aniline + cyclohexylamine (CHA) + water, aniline + CHA + octane, aniline + water + octane, and aniline + water + toluene under atmospheric pressure at (298.15 and 333.15) K are reported. The measurements were carried out by turbidity titration, gas−liquid chromatography analyses, Karl Fischer, and potentiometric titration. Predictions of the NRTL and UNIQUAC Gibbs energy models are shown based only on binary parameters of simultaneous fitting of available vapor−liquid equilibria and liquid−liquid equilibria data. In this context P−x data were measured for the system aniline + octane at 383.15 K.
