The extraction process as a kind of energy-saving and environmental protection technology can be used to separate phenols from low-temperature coal tar. The liquid–liquid equilibrium (LLE) data regarding ternary systems n-heptane + phenols + furfural were determined experimentally at 303.2, 323.2, and 343.2 K under the atmospheric pressure condition, where phenols refer to phenol, p-cresol, and 2,6-xylenol. The solvent extraction capacity was assessed by the solute distribution coefficient and selectivity. Othmer–Tobias and Bachman equations were utilized to validate the consistency of the measured data, which the linear correlation (R²) ≥ 0.99. Experimental LLE data were correlated utilizing the NRTL and UNIQUAC thermodynamic models with all of the RMSD and AARD values below 0.01, meaning that each ternary system is satisfactorily in agreement at temperatures studied and the NRTL model gives better agreement than the UNIQUAC model for ternary systems.

糠醛从烷烃中提取酚类的三元（液+液）平衡的测量和热力学建模

提取工艺是一种节能环保技术，可用于从低温煤焦油中分离酚类。在大气压力条件下，在303.2、323.2和343.2 K下，通过实验确定了三元正庚烷+酚+糠醛三元体系的液-液平衡（LLE）数据，其中酚是指苯酚，对甲酚和2,6 -二甲苯酚。通过溶质分布系数和选择性评估溶剂萃取能力。利用Othmer-Tobias和Bachman方程来验证测量数据的一致性，其中线性相关性（R ²）≥0.99。利用NRTL和UNIQUAC热力学模型将实验性LEE数据相关联，所有RMSD和AARD值均低于0.01，这意味着每个三元系统在研究温度下均令人满意，并且NRTL模型比UNIQUAC模型对三元系统的一致性更好。
