摘要：

Saturated-liquid densities and vapor pressures of HFC-143a (1,1,1-trifluoroethane), HFC-32 (difluoromethane), and HFC-125 (pentafluoroethane) were measured by a magnetic densimeter coupled with a metallic bellows in the range of temperatures from 220 to 340 K. The experimental uncertainties for temperature, pressure, and density measurements are estimated to be not greater than +/- 15 mK, +/- 10 kPa (for HFC-143a) or +/- 2 kPa (for HFC-32 and HFC-125), and +/- 0.2%, respectively. The purities of HFC-143a, HFC-32, and HFC-125 used in the present measurements are 99.0 mol %, 99.998 mass %, and 99.8 mass %, respectively.
