We studied on the phase equilibria of quaternary liquid-liquid extraction system containing acetic acid-water-binary solvent at 25℃, MEK-butyl acetate were used as binary solvents. Binodal curve, tie-line, distribution and selectivity for each quaternary system have been determined in order to investigate the effect of using binary solvent in extracting acetic acid from aqueous solution. And these experimental tie-line data were also compared with the values predicted by WAC model. It was shown that UNIFAC model is capable of predicting the tie-line in these quaternary systems within an average RSDM of 3.76 mol%.
