Resumen : High pressure density measurements were carried out for the hydrofluoroether fluid HFE-7300. A total of 159 points have been measured in the pressure range from 0.1 to 140 MPa and along seven isotherms within the temperature interval (293.15–393.15) K. To perform these measurements, an Anton Paar vibrating tube densitometer was used. The experimental high pressure density data were correlated to a Tait-like equation and compared with the available literature. By deriving the Tait-like equation, the isothermal compressibility and isothermal compressibility were also determined in the same P and T ranges. The speed of sound measurements were performed along six isotherms from 293.15 to 333.15 K at 0.1 MPa. The isentropic compressibilities were also calculated from speed of sound and density data by means of the Laplace equation
