Vapor-liquid equilibria (VLE) of binary mixtures of (hexane + fluorobenzene) and (heptane + fluorobenzene) were measured over the whole composition range in a dynamic recirculation ebulliometer at the pressure 101.4 kPa. The experimental results were well calculated by means of the NRTL and UNIQUAC thermodynamic models. The former system exhibits a shallow azeotrope in the fluorobenzene-rich zone, whereas the azeotrope lies in the heptane-rich zone for the latter one. Remarkably, the influence of the fluorine atom of the fluorobenzene molecule on the azeotrope, relative volatility, and distribution factors for both systems is found to be trivial in comparison with the homologue hydrocarbon mixtures of benzene with hexane and heptane.
