Abstract

Static dielectric constants (epsilon) were measured for mixtures of 12-dichloroethane (DCE, 1) + 2-methoxyethanol (ME, 2) + 1,2-dimethoxyethane (DME, 3) at 19 temperatures in the range -10 less than or equal to t/degrees C less than or equal to 80, employing 12 ternaries covering the whole composition range expressed by the mole fractions 0 < X(1), X(2), X(3) < 1. Empirical fitting equations of the type epsilon = epsilon(T), epsilon = epsilon(X(i)) and epsilon = epsilon(T,X(i)), which might be useful for correlation and interpolation procedures, were used to represent the experimental data. The excess mixing property epsilon(E) has been evaluated to investigate the presence of solvent-cosolvent adducts at each temperature. The quantity epsilon(E) has been found to be partly positive and partly negative in the ternary domain {X(1), X(2), X(3)}. As a consequence, it is possible to observe an isoline at epsilon(E) = 0 at each temperature. Such a line represents a large set of ternary mixtures having a pseudo-ideal dielectric behavior, even being formed by interacting components.
