Abstract

Static dielectric constants (epsilon) have been measured for pure 1,2-dichloroethane, 1,2-dimethoxyethane, and for 9 of theirs binary mixtures over the entire composition range and at 19 temperatures ranging from -10 up to +80 degrees C. The experimental data have been fitted by some empirical or quasi-theoretical equations of the type epsilon=epsilon(T), epsilon=epsilon(X(1)), and epsilon=epsilon(T,X(1)). Furthermore, the shift from ideality has been taken into account and evaluated on the basis of excess function epsilon(E) Positive deviations are detected at all experimental conditions, and a maximum occurs in the excess quantity, showing the existence of a stable solvent-cosolvent complex adduct at the stoichiometric ratio DCE : DME = 1 : 1, which may be interpreted in terms of moderately weaker interactions such as dipolarity and polarizability between dissimilar molecules.
