Abstract

PVTx property measurements in the gaseous phase for difluoromethane (1) + pentafluoroethane (2) (R32 + R125) at x₁, = 0.25 (w₁ = 12.62 %), x₁ = 0.5 (w₁ = 30.24 %), and x₁ = 0.75 (w₁ = 56.53 %) are reported. The measurements were performed by means of a magnetic suspension densimeter. 298 PVTx values for R32 + R125 mixtures were obtained over the range of temperatures (283 to 313) K and at pressures up to 2.4 MPa including the region near saturation. The experimental uncertainties are estimated to be 10 mK for temperature, 0.76 kPa for pressure, (0.03 % + 0.005 kg·m^-3) for density, and 0.18 % for mole fraction. The purities of R32 and R125 were both 99.99 %. The measurements are compared with the available data including existing equations of state.
