测定了常压下(333.15,343.15和353.15)K下甲基异丁基酮+苯酚+水三元体系的液液平衡数据。Hand和Othmer-Tobias方程证实了实验联络线数据的可靠性。用NRTL和UNIQUAC模型对实验数据进行了关联，得到了相关的二元相互作用参数。两个模型都成功地关联了实验平衡组成，均方根偏差为2.5%，而NRTL模型的关联结果更好。从分配系数和选择性来看，甲基异丁基酮在333.15~353.15℃的温度范围内都是从废水中回收苯酚的优良萃取剂，与低温萃取相比具有相当大的优势。
Liquid–liquid equilibria (LLE) data for the ternary methyl isobutyl ketone + phenol + water system have been determined at temperatures of (333.15, 343.15 and 353.15) K under atmospheric pressure. The reliability of the experimental tie-line data was confirmed by the Hand and Othmer–Tobias equations. The NRTL and UNIQUAC models were used to correlate the experimental data, and relevant binary interaction parameters were obtained. The experimental equilibrium compositions were successfully correlated by both models, with root-mean-square deviations <2.5 %, while the NRTL yielded even better correlation results. According to the distribution coefficients and selectivities, methyl isobutyl ketone is an excellent extractant to recover phenol from wastewater even in the temperature range of 333.15–353.15 K, which offers considerable advantages over extraction at lower temperatures.
