Densities and viscosities of the binary mixtures of tetrachloroethylene with methanol and of trichloroethylene with ethanol, 2-propanol, and isobutanol were measured at 303.15, 313.15, and 323.15 K. The measurements were used to compute the excess volumes (VE) and deviations in viscosity (Δη). The excess volumes and deviations in viscosity were represented by a Redlich and Kister expression.
