ABSTRACT
(Liquid liquid) equilibrium (LLE) data of the solubility curves and tie-line compositions have been determined for mixtures of (water + 2,3- butanediol + 1-butanol) 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.
