Phase diagrams of (vapour + liquid) equilibrium for binary mixtures of ,,-trifluorotoluene with ethanol, or benzene, or chloroform at pressure 101.4 kPa

摘要

(Vapour + liquid) equilibrium (VLE) of binary mixtures of (ethanol + ,,-trifluorotoluene), (benzene + ,,-trifluorotoluene), and (chloroform + ,,-trifluorotoluene) have been investigated at the pressure 101.4 kPa using the dynamic-ebulliometry method over the whole composition range. The correlated VLE phase diagrams were adequately described by means of NRTL and UNIQUAC thermodynamic models. Fair attractive energies in the first two systems are capable to yield azeotropes, while moderate repulsive energies in the later system make it zeotrope.
