In this work, high-pressure viscosity measurements for seven compositions of the binary mixture (x) HFE-7500 + (1 x) diisopropyl ether were carried out. A set of 163 points have been measured covering the temperature range (293.15-353.15) K and pressure up to 100 MPa by using a falling body viscometer with an experimental uncertainty of 2%. At 0.1 MPa, the viscosity determinations were conducted by using an Ubbelohde capillary viscometer with an uncertainty of 1%. The experimental high-pressure viscosity data were correlated as a function of pressure and temperature by employing a Vogel Fulcher Tammann equation.
