摘要：

This paper presents densities and viscosities for binary mixtures of 2-butanol + isobutanol, 2-butanol + tert-butanol, and isobutanol + tert-butanol at temperatures between (308.15 and 343.15) K over the entire composition range at atmospheric pressure. The experimental apparatus are a vibrating tube densimeter for the density measurements and a micro-viscosimeter for the viscosity measurements. Excess molar volumes, viscosity deviations, and energies of activation result from the experimental measurements. At each temperature, a Redlich-Kister equation represents the calculated excess molar volumes, viscosity deviations, and energies of activation. Also, the Grunberg-Nissan interaction model correlates the kinematic viscosities of binary mixtures with mole fractions.
