An apparatus based on the “static−analytic” method, equipped with a movable rapid online sampler−injector (ROLSI), was used to undertake the measurements. The combined expanded uncertainties are estimated at 0.11 K, 4 kPa, and 0.012 and 0.009 for the temperature, pressure, and the equilibrium liquid and vapor mole fractions, respectively. The experimental data were correlated with the Peng−Robinson equation of state using the Mathias −Copeman α function, together with the Wong−Sandler mixing rule utilizing the nonrandom two-liquid activity coefficient model.enThis document is the Accepted Manuscript version of a Published Work that appeared in final form in Journal of Chemical and Engineering Data, © 2013 American Chemical Society.Isothermal vaporLiquid equilibrium dataTetrafluoroetheneMeasurementModelingPostprint Article
