Isobaric VLE data of the ternary system (1-butanol+n-hexane+1-butylamine) and the three constituent binary mixtures at 101.3 kPa

Abstract

The isobaric vapour-liquid equilibrium has been experimentally studied for the ternary mixture (1-butanol+n-hexane+1-butylamine) and for the binary mixtures (1-butanol+n-hexane), (1-butanol+1-butylamine), and (n-hexane+1-butylamine) at 101.3 kPa. The activity coefficients were found to be thermodynamically consistent and they were satisfactorily correlated with the Margules, Van Laar, Wilson, NRTL and UNIQUAC equations. They have been also compared with the results obtained from the application of ASOG and the modified UNIFAC group contribution methods.
