DENSITIES, VISCOSITIES, AND EXCESS PROPERTIES OF TRIFLUOROETHANOL-WATER, TETRAETHYLENE GLYCOL DIMETHYLETHER-WATER, AND TRIFLUOROETHANOL-TETRAETHYLENE GLYCOL DIMETHYLETHER AT 303.15-K

Densities and kinematic viscosities of trifluoroethanol + water, tetraethylene glycol dimethylether + water, and trifluoroethanol + tetraethylene glycol dimethylether have been measured at 303.15 K and atmospheric pressure over the entire range of composition. Dynamic viscosities, excess volumes, excess viscosities, and excess Gibbs energies of activation of flow were obtained from the experimental results. The excess volumes were negative, whereas excess viscosities and energies of activation were positive, presenting the three thermodynamic properties asymmetric composition dependence. The kinematic viscosities were used to test McAllister, Stephan, and Soliman and Marshall correlations.
