VAPOR-LIQUID-EQUILIBRIA AND EXCESS-ENTHALPIES FOR BINARY-MIXTURES OF ACRYLONITRILE WITH HEXANE, CYCLOHEXANE, BENZENE, TOLUENE, 2-BUTANONE, AND ACETONITRILE

Isobaric vapor-liquid equilibrium data have been measured for binary m ixtures of acrylonitrile with hexane, cyclohexane, benzene, toluene, a nd 2-butanone. For each of these five binary mixtures and the acryloni trile + acetonitrile system excess enthalpies have been determined at 50 degrees C. Azeotropic compositions have been measured for the syste ms acrylonitrile +hexane, +cyclohexane, +benzene, and +2-butanone. The experimental data were fitted to the NRTL model using linear temperat ure dependent interaction parameters.
