Summary

PvTx properties of a binary mixture of 50 mass% HFO1123 (trifluoroethene) + 50 mass% HFO1234yf (2,3,3,3-tetrafluoroprop-1-ene) were measured in the temperature range from 294 to 410 K, in the density range between 83 kg?m-3 and 905 kg?m-3, and at pressures up to 8.1 MPa by an isochoric method, and the obtained data are compared with an equation of state (EOS) compiled in REFPROP 10.0. In addition, the critical parameters and saturated densities of the mixture were measured. Vapor-liquid equilibrium of HFO1123 + HFO1234yf was also measured at temperatures from 273 to 313 K by a recirculation method, and the binary interaction parameter of a cubic EOS was determined. Keywords: PvTx Property, Saturated Density, Critical Parameter, VLE, HFO1123, HFO1234yf.
