Tracer Diffusion Coefficients

Molar volumes and partial molar volumes, tracer diffusion coefficients (D), and shear viscosities (η) are reported for ethanol + acetonitrile mixtures at 298.15 K. The tracer diffusion coefficients vary non-additively with composition, and the product Dη for each component is composition-dependent. Albright's equation for viscosity reproduces experimental viscosities to within the combined uncertainties of the experimental data. The system exhibits considerably less complex behaviour than does the analogous water + acetonitrile system, and the properties are thought to be dominated by dipole-dipole interactions between unlike molecules.
