Abstract Isobaric vapor-liquid equilibria were obtained for the systems 1-propanol + chlorobenzene and 1-butanol + chlorobenzene at 200 and 300 kPa using a dynamic still. The mole fraction of the alcohol in the azeotropic point increases with pressure and for the 1-propanol + chlorobenzene system at 300 kPa, the azeotrope has disappeared. The two systems satisfy the point-to-point thermodynamic consistency test. Both systems show a positive deviation from ideality. The data were well correlated with the Margules, van Laar, Wilson. NRTL and UNIQUAC equations.
