VISCOSITY OF NONELECTROLYTE LIQUID-MIXTURES .4. BINARY-MIXTURES CONTAINING P-DIOXANE

Measurements of the viscosity eta and density rho are reported for eig ht binary mixtures of p-dioxane with methylcyclohexane. 1-chlorohexane , 1-bromohexane, p-xylene, propylbenzene, methyl acetate, butyl acetat e, and amyl acetate at 303.15 K. The viscosity data have been correlat ed with the equations of Grunberg-Nissan, of McAllister, and of Auslae nder. The relation among the excess viscosity Delta ln eta, excess Gib bs energy of activation Delta G(E) of viscous flow, and intermolecula r interaction in these mixtures is discussed.
