%X Kinematic  viscosities (v) have been measured for pure ethane-1,2-diol, 1,4-dioxan and for nine of their mixtures covering the entire composition range and, where possible, at 19 temperatures from -10 to +80&#176;C. The experimental values were converted into dynamic viscosities (&#951;) and were correlated with temperature and binary composition by some empirical equations. Furthermore, the excess function &#951;E and the excess Gibbs energy of activation of viscous flow &#916;G*E have been evaluated. Negative deviations from ideality are always observed for this binary system, this fact indicating strong specific interactions between unlike entities in solution to form stable solvent- cosolvent adducts. Activation enthalpies and entropies for viscous flow have been derived, and their dependence on binary composition is also discussed.
