dc.description.abstractExcess molar volumes and viscosities for binary liquid mixtures of n-alkoxyethanols + 1-propanol have been measured as a function of composition at 308.15 and 318.15 K and atmospheric pressure over the full range of composition. Excess molar volume and viscosity at 298.15 K for the mixtures, 1-propanol + diethylene glycol monobutyl ether (2-(2- butoxyethoxy) ethanol), C4H9(OC2H4)2OH and viscosity at 298.15 K for the mixtures, 1-propanol + diethylene glycol monoelhyl ether (2-(2-ethoxyethoxy) ethanol), C2H5(OC2H4)2OH have also been measured over the whole composition range. From these results deviation in viscosity, Δη, from a mole fraction average have been calculated at various temperatures. The excess volumes and viscosity deviations have been correlated using the Redlich-Kister polynomial equation by the method of least-squares for the estimation the adjustable parameters and the standard errors. McAllister's three body and four body interaction models are used to correlate the kinematic viscosities. Furthermore, Activation enthalpies, ΔH* and entropies, ΔS* of viscous flow have been evaluated and their variation with concentration discussed.en_US
