Abstract

Kinematic Viscosities (nu) of pure ethane-1,2-diol (component 1) and of nine mixtures with water (component 2) were measured at 19 temperatures ranging from -10 to +80 degrees C, and for binary compositions covering the whole miscibility field expressed by the relation 0 less than or equal to X(1) less than or equal to 1. The property fitted some empirical equations in terms of the dependences nu = nu(T) and nu(X(1)), where T is the thermodynamic temperature and X(1) is the mole fraction of ethane-1,2-diol. Furthermore, the excess function (nu(E)) and the excess Gibbs energy of activation of viscous flow (Delta G*(E)) have been investigated. The trend of nu(E) against binary composition of the mixtures shows negative deviations from ideal behaviour, while the contrary is true for Delta G*(E) The results indicate specific molecular interactions between the components, and an overview is given on the basis of the molecular dynamics of the pure species.
