Estimation of the normal boiling points of water and 1,2-dimethoxyethane through the viscosity–temperature dependence in the corresponding binary mixtures
PHYSICS AND CHEMISTRY OF LIQUIDS(2019)
Abstract
Excess quantities calculated from literature values of experimental density and viscosity in 1,2-dimethoxyethane + water binary systems (from 303.15 to 323.15 K) can lead us to test different correlation equations as well as their corresponding derivative properties. Inspection of the Arrhenius activation energy (Ea) and the enthalpy of activation of viscous flow (Delta H*) shows very close values; here, we can define partial molar activation energies Ea(1) and Ea(2) for 1,2-dimethoxyethane and water, respectively, along with their individual contribution separately. Correlation between the two Arrhenius parameters of viscosity in all compositions shows existence of main distinct interaction behaviours delimited by particular mole fractions in 1,2-dimethoxyethane. Moreover, we add that correlation between Arrhenius parameters reveals interesting Arrhenius temperature which is closely related to the vapourisation temperature in the liquid vapour equilibrium, and the limiting corresponding partial molar properties can permit us to estimate the boiling points of the pure components.
