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

摘要

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.
