Liquid–liquid equilibrium (LLE) for the methyl tert-butyl ketone (MTBK) + o-, m-, and p-cresol + water ternary systems, at temperatures of (298.2, 313.2, and 323.2) K and 101 kPa, were determined in this work. High distribution coefficient and selectivity values were calculated from the LLE data, which indicated that MTBK extracted cresols from wastewater with high efficiency. MTBK also has good physical properties (e.g., low solubility in water, suitable boiling point). The experimental results were regressed and correlated by the NRTL and UNIQUAC activity coefficient models, which both predicted LLE data in close agreement with experiments with RMSD below 3.5%. The corresponding binary interaction parameters were also regressed by these two models, which would be useful for separation process designing or optimizing.

三元体系的液-液平衡（298.2、313.2和323.2）K处的甲基叔丁基丁酮+ o-，m-，对甲酚和水

甲基叔丁基酮（MTBK）+ o-，m-和p的液-液平衡（LLE）在这项工作中确定了在（298.2、313.2和323.2）K和101 kPa温度下的甲酚+水三元体系。从LLE数据计算出高分布系数和选择性值，表明MTBK从废水中高效提取了甲酚。MTBK还具有良好的物理性能（例如，在水中的溶解度低，合适的沸点）。通过NRTL和UNIQUAC活性系数模型对实验结果进行了回归和关联，这两个模型都预测了LLE数据与RMSD低于3.5％的实验非常吻合。这两个模型还对相应的二元相互作用参数进行了回归，这对于分离过程的设计或优化将是有用的。
