Abstract

Densities and viscosities were measured over the entire range of composition for propylene glycol monomethyl ether (PGME)+water from 298.15 to 328.15 K at four isotherms. Excess volumes derived from the experimental density data were fitted to a Redlich-Kister-type relation. Excess volumes are negative over the whole range of mole fractions, and temperature has no appreciable influence on excess volumes. Values of Δ η which refer to the deviations of the viscosities of mixtures from the ideal mole fraction rule have been evaluated
