Abstract

The dielectric behaviour of binary mixtures of 1,2-dichloroethane (DCE)/ethane-1,2-diol (ED) and DCE/2-methoxyethanol (ME) has been studied at 19 temperatures in the range from -10 to +80 degrees C. The DCE/ED system is immiscible, except in a narrow range near the ED-rich region. The DCE/ME system, which is completely miscible, has been investigated over the whole composition range. Fitting procedures have been applied in order to check the suitability of empirical or semiempirical functions of the type epsilon(T), epsilon(X(i)) and epsilon(T,X(i)). Furthermore, the excess static dielectric constant, epsilon(E), has been evaluated in order to investigate the possibility of the existence of complex entities. A DCE.2ME species appears to be the only stable adduct.
