Experimental and Predicted Isobaric Vapour-Liquid Equilibrium for the Binary Systems 1,2-Dibromoethane with Isomeric Butanols

[摘要] References(18)Cited-By(2)A dynamic recirculating still was employed to measure isobaric vapour-liquid equilibrium at 40.0 and 101.3 kPa for the binary systems 1,2-dibromoethane with 1-butanol, 2-butanol, 2-methyl-l-propanol and 2-methyl-2-propanol. The experimental data were tested for thermodynamic consistency and correlated with the Margules, Van Laar, Wilson, NRTL and UNIQUAC equations. All the systems show minimum temperature azeotropes, except 1,2-dibromoethane with 2-methyl-2-propanot at 101.3 kPa. Predictions with the UNIFAC method were also obtained.
