The liquid-liquid equilibria (LLE) data and vapor-liquid equilibria (VLE) data for the binary system of epichlorohydrin (EPCH) + water were studied at 101.3 kPa. An azeotropic behavior has been found in the EPCH + water. Both the experimental LLE and VLE data were compared with the correlated values obtained by means of the NRTL and UNIQUAC equations. Both models satisfactorily correlated the experimental data. Thermodynamic consistency has been tested for the VLE data. (C) 2009 Elsevier B.V. All rights reserved.
