The liquid–liquid equilibrium (LLE) data of ternary systems n-hexane + 1-hexene + solvents (furfural and N,N-dimethylformamide) were determined experimentally at 298.2, 308.2, and 318.2 K under 101.3 kPa. The solvents’ extraction capacity was assessed by the solute distribution coefficient and selectivity. Othmer-Tobias and Hand equations were used to correlate the measured data to test the correlation of the experimental data, which the linear correlation is (R²) ≥ 0.99. Experimental LLE data was correlated utilizing the NRTL and UNIQUAC thermodynamic models with all of the RMSD and AARD values below 0.01 meaning that each ternary system satisfactory agreement at temperatures studied and the NRTL model gives a better agreement than the UNIQUAC model for ternary systems.

液-液平衡系统三元Ñ己烷+ 1-己烯+糠醛（或Ñ，ñ二甲基甲酰胺）在298.2，308.2，和318.2ķ

三元体系的液-液平衡（LLE）数据Ñ己烷+ 1-己烯+溶剂（糠醛和Ñ，Ñ二甲基甲酰胺）中在298.2，308.2实验确定，并在101.3千帕318.2ķ。通过溶质分布系数和选择性评估溶剂的萃取能力。使用Othmer-Tobias和Hand方程对测量数据进行关联以测试实验数据的相关性，线性相关性为（R ²）≥0.99。利用NRTL和UNIQUAC热力学模型将LLE实验数据进行了关联，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具有令人满意的一致性，而NRTL模型与UNIQUAC模型相比具有更好的一致性。
