Ternary (liquid–liquid) equilibrium data of furfuryl alcohol with organic solvents at T = 298.2 K: Experimental results and thermodynamic models

• Ternary LLE systems of furfuryl alcohol were studied at T = 298.2 K.
• In this work, type-1 LLE behavior was shown.
• MIBK was superior solvent for separation of furfuryl alcohol from water.
• rmsd Values for experimental and modeling correlations were less than 5%.

Basing on the importance of liquid–liquid equilibrium (LLE) data for the chemical industry, ternary LLE systems of water + furfuryl alcohol + (MIBK, ethyl acetate, furfural or n-butanol) were investigated at T = 298.2 K and atmospheric pressure. Solubility and tie-line data of these ternary LLE systems were determined by a direct measurement method. An uncertainty propagation calculation was used to validate the reliability of LLE results. Distribution coefficients (D) and separation factors (S) were calculated to evaluate the capability of selective organic solvents for separation of furfuryl alcohol from water. The correlations of experimental results with results obtained by using NRTL, UNIQUAC and UNIFAC models were presented and confirmed by rmsd values which were less than 5%.
