ABSTRACT

For separation of the azeotrope of allyl alcohol and water, three extractive agents isobutyl acetate, butyl acetate and butyl propionate were selected to extract allyl alcohol from the azeotrope. To recover the extractive agents by distillation, the isobaric vapor-liquid phase equilibrium (VLE) data for allyl alcohol + isobutyl acetate, allyl alcohol + butyl acetate and allyl alcohol + butyl propionate were measured at 101.3 kPa. With the VLE data, there is no azeotrope formed in three systems. The consistency of the measured VLE data was validated by the Herington, infinite dilution, pure component consistency and van Ness test. Moreover, the Wilson, UNIQUAC and NRTL models were used to fit the measured VLE data. All the calculated results agreed with the VLE experimental data. Meanwhile, the parameters of the Wilson, UNIQUAC and NRTL were regressed, which can be employed for the ACS Paragon Plus Environment
