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 288.15. K, 298.15. K and 313.15. K 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. ? 2011 Elsevier B.V.
