文摘

The compressed liquid viscosities of heptafluoropropyl methyl ether (HFE-7000), methoxy-nonafluorobutane (HFE-7100), ethoxy-nonafluorobutane (HFE-7200), and 2-trifluoromethyl-3-ethoxydodecafluorohexane (HFE-7500) were measured using a vibrating- wire viscometer over the temperature range of (253 to 373) K and at pressures from (0.1 to 30) MPa. The combined expanded uncertainty of the reported viscosity is about 2 % with a confidence level of 0.95 (k = 2). The experimental data were correlated with the empirical Andrade鈥揟ait equation which could reproduce the results with average absolute percentage deviations of 0.44 %, 0.38 %, 0.56 %, and 0.56 %, respectively.
