Ternary Parameters

The liquid-liquid equilibrium was measured at 20 °C in the title quaternary system and in the three nitromethane-containing ternary subsystems. The data were compared with those predicted by a superposition of the Wilson and Redlich-Kister equations including the ternary parameters. The agreement between the observed and calculated data is very good both for the quaternary system and for the three ternary systems.

Lle Data

(Liquid + liquid) equilibrium (LLE) data for the ternary mixtures of {water (1) + acetic acid (2) + ethyl acetate (3)} were determined at T = 298.2 K and atmospheric pressure.  The concentration of each phase was determined by acidimetrictitration, the Karl Fischer technique. The reliability of the experimental data wasdetermined through the Othmer–Tobias and Hand plots. Distribution coefficients and separation factorswere evaluated over the immiscibility regions. The results show that ethyl acetate is satisfactory solvent for extraction of acetic acid from water.
