Abstract : Isothermal vapor-liquid equilibrium data are reported for the binary system of hexafluoroethane and 1,1,1,2-tetrafluoroethane in the temperature range 263-353 K and in the pressure range 0.2-4.2 MPa. Areliable "static- analytic" method taking advantage of two online micro-capillary ROLSI™ samplers is used for all the measurements. The data are correlated using our in-house (ThermoSoft) thermodynamic software based on the Peng-Robinson equation of state, the Mathias-Copeman alpha function, the Wong-Sandier mixing rules, and the NRTL model.
