摘要：

As an eco-friendly compound and good solvent, cineole (1,8-cineole, eucalyptol) has been evaluated for the extraction property of phenols (phenol or p-cresol) from aqueous solutions. This paper presents experimental (liquid + liquid) equilibrium (LLE) data for the ternary (water + phenol + cineole) and (water + p-cresol + cineole) mixtures from high concentration to low concentration of phenols-water solution. The mutual solubility of the binary (water + cineole) and (water + phenol or p-cresol) systems, and the LLE results for the ternary systems were determined with a tie-line method at T = (283.15, 298.15, and 313.15)K under atmospheric pressure. The experiment LLE results showed that cineole as a good extractant exhibited high extraction ability for phenol or p-cresol from aqueous solutions. The influence of temperature on the (liquid + liquid) phase equilibria was studied. The well-known Hand and Bachman equations were used to test the reliability of the experimental values. Moreover, the experimental LLE results were satisfactorily correlated by the NRTL and UNIQUAC models. (c) 2016 Elsevier Ltd.
