چکیده:

In this work, experimental solubility and tie-line data for the (water + butyric acid + toluene)system were obtained at T = 298.2 K and atmospheric pressure. The ternary system investigated exhibits type-1 behavior of LLE. The experimental tie-line data were compared with those correlated by the UNIQUAC and NRTL models. The consistency of the experimental tie-line data was determined through the Othmer Tobias and Hand correlation equations.Distribution coefficients and separation factors were evaluated over the immiscibility regions.A comparison of the extracting capability of the solvent at different temperatures was made with respect to separation factors.
