The vapor pressure and P-V-T properties for 1,1,1,2,3,3,3-heptafluoropropane (R227ea), an ozone-friendly refrigerant, were measured using a constant volume apparatus. Measurements were carried out at temperatures from 235 K to 353 K and at pressures from 35 kPa up to 2400 kPa. The 27 measurements in the vapor pressure region were fitted with a modified Wagner equation. The 58 experimental P-V-T measurements in the superheated vapor region, taken along 5 isochores, were regressed to the virial equation of state in the Leiden form truncated after the second term. Consistency of the derived second virial coefficients was shown with the Weber correlating method. The experimental findings were also compared with published data.
