Measurements of Vapor Pressure and Saturated Liquid Density for HFE-7100

Abstract

Vapor pressure and saturated liquid density for HFE-7100 (C₄F₉OCH₃, methoxy-nonafluorobutane) were measured in the temperature range from 300 K to 400 K at intervals of 10_-3 K by the extraction method. Experimental uncertainties are 0.028 K for temperature, 0.4 kPa for pressure and 0.7 kg‧m for density. On a basis of the present data, correlations of vapor pressure and saturated_{- 3} liquid density were formulated. The standard deviations from correlations were 0.6 kPa for vapor pressure and 0.4 kg‧m for saturated liquid density.
