Experimental investigation of the density of hydrofluoroether HFE-73DE and its binary mixtures with ethyl acetate

This paper presents an experimental investigation of the density of hydrofluoroether HFE-73DE and its binary mixtures with ethyl acetate. Density measurements were carried out at atmospheric pressure in the temperature range 293–328 K using a Coriolis-type mass flow meter (Endress+Hauser Promass) operated in static mode. For both the pure fluid and the mixtures, density decreases approximately linearly with temperature, with the slope dependent on mixture composition. The resulting data set supports the development and validation of density correlations for HFE-73DE + ethyl acetate mixtures relevant to compact heat exchangers and electronics cooling applications.
