Abstract

Static dielectric constants (epsilon) were determined for the 1,2-dichloroethane (DCE, 1)/2-chloroethanol (CE, 2) binary solvent system at 19 temperatures ranging from -10 to +80 degrees C and in the whole composition range expressed by the mole fraction 0 less than or equal to X(1) less than or equal to 1. The experimental values have been fitted to some equations that could be usefully employed for predictive epsilon calculations. Furthermore, the excess mixing properties (epsilon(E)) have been evaluated in order to point out the presence of solvent-cosolvent adducts in the binary mixtures mentioned above. The values of epsilon(E) have been generally found to be negative and only slightly positive under a few experimental conditions in the CE rich-region, thus giving evidence of a close interaction network probably via hydrogen bonding as well as other interactions of every kind in this solvent system.
