ABSTRACT
Liquid liquid equilibrium (LLE) data for the ternary system water + ethylbenzene + acetophenone and water + ethylbenzene + 1-phenylethanol were determined at temperatures T = (298.2, 308.2, 318.2, and 328.2) K and atmospheric pressure. The immiscibility region was found to be relatively small and not sensitive to the change of temperature. The Othmer Tobias and the Bachman correlations were used to test the consistency of the LLE data. The experimental data were correlated by both the nonrandom two-liquid and the universal quasichemical activity coefficient models. The relevant model interaction parameters were regressed by data fitting. The model correlated results show good agreement with the measured data. The obtained interaction parameters can be used in the calculation of LLE for the ternary system water + ethylbenzene + acetophenone and water + ethylbenzene +1-phenylethanol as well as for the design and optimization of the related separation process.
