Abstract
Liquid-liquid equilibrium (LLE) data for {water + furfuryl alcohol + solvent (isopropyl ether, tert-butyl methyl ether, dichloromethane and methyl isobutylcarbinol)} ternary systems were determined at T = 298.2 K and p = 101.3 kPa. The distribution coefficients and separation factors were evaluated and the results showed that those solvents can effectively for furfuryl alcohol recovery from aqueous solutions. The Othmer-Tobias, Bachman and Hand equations were employed to validate the reliability of the experimental LLE data. Additionally, the experimental LLE data were correlated using the NRTL and UNIQUAC models and the binary interaction parameters were optimized. The root mean square deviations (RMSD) between the correlated data by NRTL and UNIQUAC models and the experimental LLE data were less than 0.36%, which demonstrated that both models can correlate experimental LLE data successfully.
