摘要：
On this paper, experimental (liquid + liquid) equilibrium (LLE) results are presented for systems composed of beta-citronellol and aqueous 1-propanol or acetone. To evaluate the phase separation properties of beta-citronellol in aqueous mixtures, LLE values for the ternary systems (water + 1-propanol + beta-citronellol) and (water + acetone + beta-citronellol) were determined with a tie-line method at T = (283.15, 298.15, and 313.15 +/- 0.02) K and atmospheric pressure. The reliability of the experimental tie-lines was verified by the Hand and Bachman equations. Ternary phase diagrams, distribution ratios of 1-propanol and acetone in the mixtures are shown. The effect of the temperature on the ternary (liquid + liquid) equilibria was examined and discussed. The experimental LLE values were satisfactorily correlated by extended UNIQUAC and modified UNIQUAC models. (C) 2015 Elsevier Ltd. All rights reserved.
