摘要: Abstract A dynamic recirculating still was employed to measure isobaric vapour–liquid equilibrium at the pressures of 40.0, 66.6 and 101.3 kPa for binary systems 1,2-dichloroethane with 1-butanol, 2-butanol, 2-methyl-1-propanol 2-methyl-2-propanol. The experimental data were tested thermodynamic consistency, calculated activity coefficients have been correlated using Wilson, NRTL UNIQUAC equations. mixtures containing 2-methyl-2-propanol show minimum temperature azeotropes. Predictions UNIFAC method also obtained.
