Abstract
Relative permittivities (є) were determined for ternary ethane-1,2-diol (component 1)/2- methoxyethanol (component 2)/water (component 3) mixtures at five temperatures ranging from 5 to 25°C and over the mole fraction composition range 0 ≤ Xi ≤ 1. The data have been fitted to a model equation that could be useful for predictive є calculations. From the measured є values, the excess relative permittivity єE has been evaluated in order to test for three-component adducts. The values of єE have been found to be negative for all the ternary mixtures under all the experimental conditions, which suggests a strong interaction network through hydrogen bonding, although evidence for a discrete three-component adduct was not forthcoming.
