  • Abstract It is observed that operation at a stable steady state is not easy in a distillation column of purifing acetic acid from water using isopropyl acetate as an entrainer. In order to find out the reason of such phenomenon, the phase behavior, the vapor-liquid equilibrium (VLE) and liquid-liquid equilibrium (LLE), of isopropyl-water-acetic acid mixture was studied experimentally. The VLE data of acetic acid-water and acetic acid-isopropyl acetate and VLE and LLE data of acetic acid-water-isopropyl acetate were measured with different equilibrium cells at 760 mmHg with a pressure controlled system.
    The experimental data were correlated with the NRTL and the UNIQUAC models. The association effect of acetic acid in vapor phase was considered by the Marek and Standart’s semi-chemical theory and the Hayden-O’Connell’s method. The correlation results show that the the NRTL model associated with Hayden-O’Connell’s consideration has better agreement than that of the Marek and Standart’s semi-chemical theory.
