The liquid density, liquid kinematic viscosity, and surface tension of the segregated hydrofluoro ethers (HFEs) HFE-7000 (1,1,1,2,2,3,3-heptafluoro-3-methoxy-propane), HFE-7100 (mixture of the isomers 1,1,1,2,2,3,3,4,4-nonafluoro-4-methoxy-butane and 1,1,1,2,3,3-hexafluoro-3-methoxy-2-(trifluoromethyl)propane), HFE-7200 (mixture of the isomers 1-ethoxy-1,1,2,2,3,3,4,4,4-nonafluorobutane and 1-ethoxy-1,1,2,3,3,3-hexafluoro-2-(trifluoromethyl)propane), HFE-7300 (1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-(trifluoromethyl)pentane), and HFE-7500 (3-ethoxy-1,1,1,2,3,4,4,5,5,6,6,6-dodecafluoro-2-(trifluoromethyl)hexane) were studied in dependence on temperature under saturation conditions. A vibrating-tube densimeter was used for the measurement of the saturated-liquid density at temperatures from (273.15 to 363.15) K with a relative expanded uncertainty (k = 2) of 0.02 %. The kinematic viscosity of the liquid phase and surface tension were obtained on the basis of surface light scattering (SLS) measurements for temperatures between (273.15 and 373.15) K with estimated relative expanded uncertainties (k = 2) of (2 and 1.5) %. The measured data could be correlated within their expanded uncertainties (k = 2) by interpolating expressions. Effects of the molecular structures of the studied HFEs on the thermophysical data are discussed. In particular for viscosity and surface tension, comparison with literature data is restricted by their scarce availability.
