Vapor pressure and saturated liquid density for 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone were measured in the temperature range from 300 K to 400 K at intervals of 10 K by the extraction method. The author obtained 11 data points of vapor pressure in the range of 42 kPa to 825 kPa and saturated liquid density in the range of 1210 kg‧m-3 to 1598 kg‧m-3. On the basis of the present data, correlations were formulated. The maximum deviations from correlations were 0.8 kPa for vapor pressure and 0.4 kg‧m-3 for saturated liquid density. The normal boiling point and acentric factor were determined to be 321.95 K and 0.465, respectively. In addition, the saturated vapor pressure and vaporization of heat were also calculated.
