Abstract

A detailed dielectric study of 2-methoxyethanol (ME)-water (W) mixtures has been carried out as a function of temperature in the range - 10 to + 80-degrees-C and over the entire binary composition range (0 less-than-or-equal-to x less-than-or-equal-to 1). The experimental data, obtained by the heterodyne beat method at 2 MHz, were used to test some empirical relations of the type epsilon = epsilon(T), epsilon = epsilon(x) and epsilon = epsilon(T, x), in order to assess the empirical performances in dielectric behaviour of these mixtures, including the experimental conditions which are able to modify such patterns. The data reported here for ME-W binary mixtures were useful trying to understand the relative discriminating ability of both components towards cooperative intermolecular interactions in the liquid state, the quantitative similarities and differences between the chosen pure species, the intermolecular phenomena and interactions influencing the dielectric properties of the mixtures and the usefulness of a qualitative description of the possible formation of solvent-cosolvent complex species involving hydrogen-bonding, dipole-dipole and other interactions.
