    The aim of this paper is to obtain liquid-liquid equilibrium (LLE) data for cyclopentanone extraction. Ternary LLE systems of water + cyclopentanone + organic solvents (MIBK, ethyl acetate, furfural or n-butanol) were investigated at T = 298.2 K and atmospheric pressure. The solubility and tie-line data of these ternary LLE systems were determined by direct analysis. The reliability of the LLE experimental results was validated by the Othmer-Tobias and Hand correlation equations. Distribution coefficients (D) and separation factors (S) were calculated in order to evaluate the capability of selective organic solvents for cyclopentanone extraction. NRTL and UNIQUAC models were employed to correlate the results obtained by the modeling with the experimental data. Good correlation results were confirmed by the rmsd values of less than 6%. © 2014 Elsevier B.V.
