“…The equilibrium data of the ternary mixture were predicted by UNIFAC method and the method using the interaction parameters of CH, CH 2 , CH 3 , OH, COOH, and H 2 O functional groups obtained by Reid et al [13]. The calculated tie-lines (dashed lines) are presented in figures 1 to 3.…”

“…Several studies have been carried out to obtain LLE data on the extraction of lactic acid from its dilute aqueous solutions [12,13]. In this paper, we report the LLE results for the four ternary system (water + lactic acid + octanol), (water + lactic acid + nonanol), and (water + lactic acid + decanol) at T = 298.15 K, for which no such data are available.…”

Experimental liquid-liquid equilibria of the ternary system of (water + lactic acid + butyl acetate) were studied at T= (298.15, 303.15 and 308.15) K under atmospheric conditions. Complete phase diagrams were obtained by determining solubility and tie-line data. The ternary system exhibits type-1 behavior of LLE. The reliability of the experimental tie-line data was ascertained by using both Hand and Othmer-Tobias correlations. The UNIFAC group contribution method was used to predict the observed ternary liquid-liquid equilibrium data. Distribution coefficients and separation factors were evaluated to evaluate the extracting capability of the solvent. Separation factors were more than unity and the UNIFAC prediction was satisfactory.
