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 353Kand in the pressure range 0.2 4.2MPa.Areliable static-analytic method taking advantage of two online micro-capillary ROLSITM 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, theWong Sandler mixing rules, and the NRTL model.
