Density, dynamic viscosity, and derived properties of binary mixtures of 1,4 dioxane with water at T=298.15 K

Densities and dynamic viscosities for 1,4dioxane with water, at several temperatures T=298.15 K have been measured over the whole composition range and 0.1 MPa, along with the properties of the pure components. Excess molar volumes, viscosity deviations, and excess free energy of activation for the binary system at the above-mentioned temperature are deduced. The viscosity of a mixture depends on the molecular interactions between the component mixtures with strong interactions between different molecules show positive viscosity deviations and negative excess molar volume confirming recent works that affirmed the water-1,4dioxane cluster formation.
