Experimental and Predicted Isobaric Vapor-Liquid-Equilibrium for the Binary-Systems 1,2-Dibromoethane with Isomeric Butanols
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-1-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-propanol at 101.3 kPa. Predictions with the UNIFAC method mere also obtained.
