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.
