Densities and viscosities have been determined as a function of mole fraction for propylene carbonate + 1,2-dimethoxyethane at 298.15, 308.15, and 318.15 K. The excess molar volumes (V(m)E) have been calculated from the results. The values of V(m)E are found to be negative over the entire composition range and at all three temperatures studied. Kinematic viscosity data have been used to calculate the interaction parameters (nu12 and nu21) for the three-body interactions of the McAllister equation.
