This paper reports PVTx properties for the HCFC 142b + HCFC 22 system in a wide range of temperatures from 297 to 443, of pressures from 0.5 to 10.0 MPa, and of densities from 72 to 1079 kg/m[sup 3]. For 4 compositions, i.e., 20, 40, 60, and 80 wt % HCFC 142b, 422 PVTx measurements have been made along 31 isochores. The uncertainties of the temperature, pressure, and density measurements are less than [plus minus]10 mK, [plus minus]3.0 kPa, and [plus minus]0.1%, respectively. From the PVTx measurements for 20, 40, 60, and 80 wt % HCFC 142b, the authors determine dew points and bubble points, enabling us to construct the dew- and bubble-points curves for each composition. The authors also compare the vapor-liquid equilibrium data along three isotherms, where the experimental data are reported by others, with the vapor-liquid equilibrium curve calculated from the Raoult's law.
