The viscosity of pure 2, 2, 2 trifluoroethanol and its aqueous solutions of 85 mol% and 60 mol% has been measured in the temperature range 273 - 453 K and at pressures up to 40 MPa by a closed circuit capillary viscometer. No experimental data are reported for the pressure dependence of the viscosity of these mixtures so far. The experimental error of the present measurement is estimated at ±1.1%. The measured data were correlated with an equation of the viscosity in terms of temperature and pressure for each mixture. At atmospheric pressure, additional measurements were performed with the aid of a Ubbelohde viscometer over the whole range of composition was confirmed.
