ABSTRACT

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 microviscosimeter 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.
