Özet

The system {(water (1) + butyric acid (2) + phenyl acetate (3)} at different temperatures, such as 298.15 K, 308.15 K, 318.15 K, and at a constant pressure (101.3 +/- 0.5 kPa) in terms of liquid liquid phase equilibria were investigated. The solubility curves for each system were found. The consistency for the experiments to determine tie-lines was done by Othmer-Tobias method. NRTL and UNIQUAC equation correlated experimental data with good results. the consistency of UNIQUAC and NRTL for concerning ternary experimental data. The finest results were reached with UNIQUAC model (RMSD value is 0.087 for 298.15 K). Extraction ability of the solvents used in this study were assessed in term of distribution coefficients (D) (highest 5.20) and separation factors (s(f)) (highest 322).
