Liquid–liquid equilibrium (LLE) data for the ternary mixture of water + furfuryl alcohol (FAL) + {1-pentanol and n-propyl acetate} was measured in 101.3 kPa at 303.2, 313.2, and 323.2 K. The separation factor (S) and distribution coefficient (D) appraised the utility of extracting FAL from water. The experimental data were accurately correlated by the nonrandom two-liquid (NRTL) and the universal quasi-chemical (UNIQUAC) models with the root-mean-square deviation (RMSD%) values. The values are less than 0.37%. The relevant binary interaction parameters were calculated. The GUI-MATLAB was used to check the consistency of the calculated binary interaction parameters and liquid–liquid equilibrium data. The σ-profiles can analyze the molecular interaction, which further confirms the accuracy of the experimental results. The excellent performance of 1-pentanol and n-propyl acetate in the extraction of FAL from an aqueous solution was shown.
