Abstract
Liquid-liquid equilibria of the system water + acetic acid + 2-hexanone at 25 degreesC and 35 degreesC were studied to evaluate 2-hexanone as an extra ction agent in aqueous solutions of acetic acid. The experimental data were fitted using the NRTL and UNIQUAC equations. Equilibrium predictions, appl ying the UNIFAC method, were also made with the use of liquid-liquid equili brium specific parameters for both temperatures.
