ABSTRACT
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 for 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-Tamman (VFT) equation.
