Vapor−Liquid Equilibria at 453.25 K and Excess Enthalpies at 363.15 K and 413.15 K for Mixtures of Benzene, Toluene, Phenol, Benzaldehyde, and Benzyl Alcohol with Benzyl Benzoate

Abstract

Isothermal P−x data at 453.25 K and excess enthalpies at 363.15 K and 413.15 K are presented for binary systems of benzyl benzoate together with benzene, toluene, phenol, benzaldehyde, and benzyl alcohol. As pointed out previously (Nienhaus, B.; Limbeck, U.; Bolts, R.; de Haan, A. B.; Niemann, S. H.; Gmehling, J. J. Chem. Eng. Data 1998, 43, 941−948), information about the real behavior of systems including these components is very important, especially for the production of phenol by toluene oxidation. In addition, these data will be used for the introduction of a new aromatic ester group (AC−COO−) into modified UNIFAC (Dortmund), which is part of the revision, extension, and further development of this group contribution method. The vapor−liquid equilibrium (VLE) data of four systems were measured using a static apparatus. The corresponding experimental excess enthalpy (HE) data were determined with the help of an isothermal flow calorimeter. For the simultaneous description of VLE and HE data the NRTL ...
