摘要：Abstract: Liquid–liquid equilibrium data for the n-heptane + phenol + sulfolane system were obtained at 323.15 and 343.15 K under 101.35 kPa pressure. The distribution coefficient (K) and separation factor (S) were calculated to assess the effectiveness of extracting phenol from n-heptane, and the consistency of LLE date were verified by the Othmer–Tobias, Hand as well as Bachman equations. The experimental data were correlated by using NRTL and UNIQUAC models, and the root-mean-square deviation (RMSD) values of both models were below 0.59%, demonstrating the two models were successfully describe the experimental data. ? 2018, Pleiades Publishing, Ltd.
