Speeds of sound for the binary system HFE-7500 + Diisopropyl ether have been measured at pressures up to 100 MPa and within a temperature interval from (293.15 to 353.15) K. High pressure density measurements were carried out by using a U-tube densimeter up to 140 MPa and at temperatures from (293.15 to 393.15) K. Additionally, the density and the isentropic compressibility were evaluated from integration of speed of sound data in the pressure range from (0.1 to 100) MPa and in the temperature interval from (293.15 to 353.15) K. This work also reports a correlation for both the density and the speed of sound within their estimated uncertainties to evaluate the volume and its derivatives with respect to pressure and temperature.
