ABSTRACT

In this investigation isothermal vapor-liquid equilibrium data (VLE) and excess enthalpy data were measured for the binary systems required for the design of reactive distillation processes for the ethyl acetate production. The isothermal P-x data was measured with a static apparatus, the heat of mixing measurements were performed with a commercial isothermal flow calorimeter. To the experimental data from this work and mixture data from other authors temperature dependent UNIQUAC parameters were fitted.
