ABSTRACT

Isobaric vapor liquid equilibrium data (VLE) for two binary systems, 2-methyl-1-butanol (1) + dimethylformamide (DMF) (3) and 2-methyl-butanol acetate (2) + DMF (3), and the ternary system 2-methyl-1-butanol (1) + 2-methyl-butanol acetate (2) + DMF (3) were measured in a modified Rose recirculation still at 101.3 kPa. Wilson and nonrandom two-liquid (NRTL) models were applied to correlate the binary systems VLE data, which had been examined by thermodynamic consistency test in the first place, and the model parameters were obtained. These parameters were used to predict the ternary VLE data, which yielded a good agreement with the experimental values.
