Separation of azeotrope (allyl alcohol + water): Isobaric vapour-liquid phase equilibrium measurements and extractive distillation

To separate the azeotrope of (allyl alcohol + water) by extractive distillation, N-methyl-2-pyrrolidone, N-methyl formamide and ethylene glycol were selected as extractive agents, and the isobaric VLE data for the binary systems of (allyl alcohol + N-methyl-2-pyrrolidone), (allyl alcohol + N-methyl formamide) and (allyl alcohol + ethylene glycol) were determined at 101.3 kPa by a modified Rose type recirculating still. The thermodynamic...
