摘要

为了从水中分离苯酚，在101.3 kPa下，分别在298.15、303.15和313.15 K获得了水+苯酚+溶剂（三氯甲烷、异戊醇）的液液平衡（LLE）数据。巴赫曼方程和汉德方程用于验证 LLE 数据的可靠性，其线性系数大于 0.98%。将 LLE 数据与 NRTL 和 UNIQUAC 模型相关联，得到二元交互作用参数，其 RMSD 不大于 0.36%。

Ternary (Liquid–Liquid) Equilibrium Experiment and Thermodynamic Modeling for Extraction of Phenol from Water with Different Solvents at Several Temperatures

In order to separate phenol from water, at 101.3 kPa, the liquid-liquid equilibria (LLE) data of water + phenol + solvents (trichloromethane, isoamyl alcohol) were obtained at 298.15, 303.15, and 313.15 K. The ability of the extractant to extract phenol from water was evaluated by the distribution coefficient (D) and selectivity coefficient (S). The Bachman and Hand equations were used to verify the reliability of the LLE data with the linear coefficient was greater than 0.98%. The LLE data was correlated with the NRTL and UNIQUAC models to obtain a binary interaction parameter with an RMSD not greater than 0.36%.

期刊介绍： Journal of Solution Chemistry offers a forum for research on the physical chemistry of liquid solutions in such fields as physical chemistry, chemical physics, molecular biology, statistical mechanics, biochemistry, and biophysics. The emphasis is on papers in which the solvent plays a dominant rather than incidental role. Featured topics include experimental investigations of the dielectric, spectroscopic, thermodynamic, transport, or relaxation properties of both electrolytes and nonelectrolytes in liquid solutions.
