摘要：
Pressure-volume-temperature (PVT) properties and vapor pressures of HFC-125 (pentafluoroethane; CHF2CF3) have been experimentally obtained. Vapor pressures of HFC-125 have been measured in the range of temperatures from 223 to 338 K and pressures up to 3.54 MPa with uncertainties of 5 mK and 2.5 kPa, respectively. The vapor pressure equation for this substance was correlated based on the present data. PVT properties of HFC-125 have been determined with a constant-volume apparatus in the range of temperatures from 280 to 473 K, pressures up to 17 MPa, and densities up to 1145 kg . m(-3) with uncertainties of 5 mK, 2.5 kPa, and 0.01%, respectively. All of the available experimental PVT property data were compared with the equation of state correlated by Wilson et al.
