ABSTRACT

Isothermal vapor-liquid equilibrium (VLE) data for the binary systems propane + dimethyl ether and propene + dimethyl ether were determined experimentally with the static synthetic and the static analytic methods. Additionally, excess enthalpy (HE) data were determined by means of an isothermal flow calorimeter. For the system propane + dimethyl ether, the azeotropic compositions were derived graphically from the VLE data. The experimental data from this work were correlated by using a linear temperature dependence for the UNIQUAC interaction parameters and by treating the real vapor phase behavior with the Soave-Redlich-Kwong equation of state. On the basis of this correlation, the new data were compared to values taken from the literature.
