ABSTRACT

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.
