Liquid–liquid equilibria provide basic data and guidance regarding the design, simulation, and development of an appropriate solvent extraction process. In the current work, the data for the liquid–liquid equilibrium (LLE) of water + cyclohexanone + isophorone and water + cyclohexanone + mesityl oxide systems have been measured at temperatures of 308.15–328.15 K and pressure of 101.3 kPa. The empirical Bachman and Hand equations were utilized to confirm the consistency of experimentally determined LLE data. Meanwhile, the solute distribution ratio and separation parameter were obtained from the experimental equilibrium data to evaluate the extraction properties of the selected solvents. Additionally, a mathematical regression of experimental tie-line compositions for all of the investigated ternary mixtures was performed by means of the nonrandom two-liquid and universal quasi-chemical activity coefficient models to acquire corresponding optimized binary interaction parameters. The correlation results were verified to be coincident with the experimental ones and revealed that the above two thermodynamic models were of high-accuracy and suitable to regress the tie-line compositions for the investigated ternary systems.

通过异佛尔酮或间苯三酚氧化物从水中分离环己酮的三元（液体+液体）平衡的测量和相关性

液-液平衡为适当的溶剂萃取工艺的设计，模拟和开发提供了基本数据和指导。在当前工作中，水+环己酮+异佛尔酮和水+环己酮+异丁烯氧化物系统的液-液平衡（LLE）数据已在308.15–328.15 K的温度和101.3 kPa的压力下进行了测量。经验巴赫曼和汉德方程被用来确认实验确定的LEE数据的一致性。同时，从实验平衡数据中获得溶质分布比和分离参数，以评价所选溶剂的萃取性能。此外，利用非随机两液和通用准化学活性系数模型对所有研究的三元混合物进行了实验联系线组成的数学回归，以获取相应的优化二元相互作用参数。验证了相关结果与实验结果吻合，并表明上述两个热力学模型具有很高的准确性，适合于回归所研究的三元体系的联系线组成。
