摘要
The dielectric behaviour of binary mixtures of N,N-dimethylformamide (DMF) + 1,2-dichloroethane (DCE) has been studied at 19 temperatures in the -10 less than or equal to t/C-0 less than or equal to +80 range, employing the pure species and 9 mixtures of theirs covering the whole composition range (0 less than or equal to X(i) less than or equal to 1). Some fitting procedures have been applied in order to check the suitability of empirical relations of the type epsilon = epsilon(T), epsilon = epsilon(X(i)) and epsilon = epsilon(T, X(i)). Furthermore, the excess function (epsilon(E)) has been evaluated in order to investigate the possibility of existence of complex moieties. The DMF . DCE adduct appears to be the only stable heteroassociated species.
