Abstract Liquid-liquid equilibria(LLE) data for ternary systems of water + 1,6-hexanediol + 1-pentanol/ 3-methyl-1-butanol/ 2-methyl-2-butanol were measured at (293.15, 303.15, 313.15 and 323.15) K under 101.3kPa. Cloud-point method was applied to determine the solubility curves data. Distribution coefficient and separation factors for 1,6-hexanediol were calculated from the measured tie-line data to evaluate the extraction effect of alcohols on 1,6-hexanediol. The reliability of experimental LLE data were tested by Othmer–Tobias equation and Hand equation, NRTL and UNIQUAC models were applied to correlate the measured data and the calculated results show that both models can fit the experimental data very well.

不同温度下水 + 1,6-己二醇 + 1-戊醇/3-甲基-1-丁醇/2-甲基-2-丁醇的实验和相关液-液平衡数据

摘要 在 (293.15, 303.15, 313.15 和323.15) 101.3kPa 下的 K。应用浊点法测定溶解度曲线数据。根据测量的连接线数据计算 1,6-己二醇的分配系数和分离因子，以评估醇对 1,6-己二醇的萃取效果。实验LLE数据的可靠性通过Othmer-Tobias方程和Hand方程进行检验，应用NRTL和UNIQUAC模型对实测数据进行关联，计算结果表明两种模型都能很好地拟合实验数据。
