Abstract

The liquid density and surface tension of nonafluorobutylmethylether(HFE7100) were measured over the range from 279.15 K to 321.15 K and 22 groups of the experimental data were obtained.These data were used to fit the equations of the liquid density and surface tension.The average relative deviation and the maximum relative deviation between the experimental values and the calculated ones of density were only-0.008 09% and-0.009 86%,respectively,and the absolute deviation between the calculated surface tension from the equation and the experiment results was within ±0.015 mN·m-1.The surface tension of HFE7100 was calculated with five theoretical correlations and it is indicated that the results by the Zuo-Stenby(Z-S) correlation have the minimum deviation from the experiment data,with a maximum value of-1.899 %.The results of this research may be useful for the engineering application of HFE7100.
