ASSOCIATING BEHAVIOR OF MIXED LIQUIDS - DIELECTRIC-PROPERTIES OF THE ETHANE-1,2-DIOL+1,4-DIOXAN SOLVENT SYSTEM FROM -10-DEGREES-C TO +80-DEGREES-C

The associating behaviour of ethane-1,2-diol (component 1)+1,4-dioxan (component 2) in their binary mixtures has been investigated through their dielectric properties. The experimental measurements of the relative permittivity (epsilon) in the temperature range -10 less than or equal to t/degrees C less than or equal to 80 for nine binary mixtures covering the whole miscibility field 0 less than or equal to X(1) less than or equal to 1 have been utilized to test empirical equations representing the functions epsilon = epsilon(T), epsilon = epsilon(X(1)) and epsilon = epsilon(T, X(1)) Furthermore, the excess mixing function, epsilon(E), has been evaluated to obtain qualitative and quantitative information about the possibility of 'solvent-cosolvent' complex formation.
