摘要：Liquid-liquid equilibrium data of the solubility curves and tie-line compositions were determined for ternary systems of water + acetyl acetone + propyl acetate at 288.15K, 298.15K and 313.15K and atmospheric pressure. Distribution coefficients were evaluated for the immiscibility region. The reliability of the experimental tie-lines has been confirmed by using Othmer-Tobias and Bachman correlation. The experimental data were fitted using the NRTL and UNIQUAC equations, parameters of these two models were regressed. (C) 2011 Elsevier B.V. All rights reserved.
