Isobaric VLE data for the binary systems dibromomethane with isomeric butanols at 40.0 and 101.3 kPa

Isobaric vapour-liquid equilibrium data at 40.0 and 101.3 kPa for the binary systems dibromomethane with 1-butanol, 2-butanol, 2-methyl-1-propanol and 2-methyl-2-propanol are reported. All the systems show minimum temperature azeotropes. The experimental data were tested for thermodynamic consistency and correlated with the Margules, Van Laar, Wilson, NRTL and UNIQUAC equations. Predictions with the UNIFAC method were also obtained.
