ABSTRACT

The isobaric vapor liquid equilibrium (VLE) data of n-butanol + SBAC, isobutanol + SBAC, and tert-butanol + SBAC binary systems were determined at 101.3 kPa by using an Ellis vapor liquid equilibrium still. The experimental data passed the thermodynamic consistency test by Herington method and showed positive deviations from ideal behavior. The VLE values were correlated by the Wilson, NRTL and UNIQUAC activity-coefficient models with satisfactory results. The results show that n-butanol + SBAC and isobutanol + SBAC systems form minimum temperature azeotropic mixtures.
