Abstract
In this work, densities ρ, speeds of sound u, and viscosities η, have been measured over the whole composition range for the binary mixtures of diethylene glycol monomethyl ether (DEGMME), CH3(OCH2CH2)2OH with 1-hexanol, CH3(CH2)5OH, 1-octanol, CH3(CH2)7OH, and 1-decanol, CH3(CH2)9OH at T = (293.15, 298.15, 303.15, and 308.15) K along with the properties of the pure components. By using the experimental values of ρ, u, and η , excess molar volume, VmE, deviations in viscosity, Δη, isentropic compressibility κS, deviations in isentropic compressibility ΔκS, deviations of the speed of sound Δu, have been calculated. The viscosity results have also been analysed in terms of some semi-empirical equations.
