For separation of the mixtures cyclohexanone with alcohols by distillation, the isobaric vapor–liquid equilibrium data for cyclohexanone + (ethanol/n-propanol/isopropanol) were measured at 101.3 kPa. The van Ness, pure component consistency, and Herington test were used to validate the measured data consistency. The measured data were fitted by the Wilson, NRTL, and UNIQUAC models with the optimized binary parameters.

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.
