ABSTRACT

Liquid liquid equilibrium (LLE) data of the solubility curves and tie-line compositions have been determined for mixtures of (water + 2,3- butanediol + ethyl acetate) at 298.15, 308.15 and 318.15K and atmospheric pressure. Distribution coefficients and separation factors have been evaluated for the immiscibility region. The reliability of the experimental tie lines has been confirmed by using Othmer Tobias correlation. The LLE data of the ternary systems have been predicted by UNIFAC method.
