ABSTRACT

Isobaric vapor liquid equilibrium (VLE) data have been determined with a circulation still at 101.3 kPa for binary systems of acetone + isopropenyl acetate, 2-butanone + isopropenyl acetate, and isopropenyl acetate + acetylacetone. No azeotropic behavior was found in any of the systems studied. Thermodynamic consistency has been tested for all VLE data. The experimental data have been correlated satisfactorily by the NRTL, UNIQUAC, and Wilson models. Predictions by using group-contribution methods, such as the original UNIFAC, UNIFAC-Dortmund, and UNIFAC-Lyngby, have been compared with the experimental results.
