Abstract

Densities and kinematic viscosities of the ternary mixture water-trifluoroethanol-tetraethylene glycol dimethyl ether have been measured at 303.15 K and atmospheric pressure over the entire range of compositions. Excess molar volumes and excess viscosities were obtained from the experimental results. The excess volumes were negative and excess viscosities were positive, indicating the asymmetric composition dependence of the two thermodynamic properties. The excess volumes have been correlated by the Redlich-Kister equation and the kinematic viscosity data have been fitted using the Stephan and Heckenberger correlation.
