The vapor pressures of 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea) and 1,1,1,3,3-pentafluoropropane (HFC-245fa), two ozone-friendly fluorinated propane derivatives, were measured with a modified Burnett apparatus. The vapor pressures were measured at temperatures from (253 to 373) K and pressures from (87 to 2824) kPa for HFC-227ea and at temperatures from (255 to 393) K and pressures from (21 to 1950) kPa for HFC-245fa. The measurement uncertainties were estimated to be within +/-10 mK and within +/-1 kPa. The Wagner-type vapor pressure equations were used to correlate the experimental data for HFC-227ea and HFC-245fa, respectively. The results were also compared with available literature data.
