ABSTRACT

Isobaric vapor liquid equilibrium (VLE) measurements are reported for binary mixtures of vinyl acetate and ethyl formate with cumene at 97.3 kPa. The data were obtained using a vapor recirculating type (modified Othmer s) equilibrium still. Both mixtures show positive deviation from ideality. None of the systems form an azeotrope. The experimental data obtained in this study are thermodynamically consistent according to the Herington and Black tests. The activity coefficients have been satisfactorily correlated by means of the Margules, Redlich Kister, and NRTL equations. A comparison of the values of activity coefficients obtained by experimental data with the UNIFAC model is included in this paper.
