Liquid鈥搇iquid equilibria (LLE) data for two ternary systems: methyl butyl ketone (MBK) + phenol + water and methyl butyl ketone + hydroquinone + water have been measured at 298.15 K and 323.15 K under atmospheric pressure. The reliability of experimental tie-line data was checked by Hand and Bachman equations. The distribution coefficient and selectivity were used to evaluate the extraction performance of methyl butyl ketone. In addition, NRTL (nonrandom two-liquid) and UNIQUAC (universal quasi-chemical activity coefficient) models were used to correlate experimental data, which yielded corresponding binary interaction parameters. Results from both models agree with each other well. NRTL model presents a stronger predictive power than UNIQUAC model.
