TLDR
In this article, the authors measured densities and viscosities for anisole with 2-butanol, 2-methyl-1-propanol, and 2methyl-2-propanol binary liquid mixtures with a vibrating-tube densimeter and Cannon-Fenske routine viscometers over the temperature range between 303.15 and 323.15 K and at atmospheric pressure.Abstract:
Densities and viscosities were measured for anisole with 2-butanol, 2-methyl-1-propanol, and 2-methyl-2-propanol binary liquid mixtures with a vibrating-tube densimeter and Cannon-Fenske routine viscometers over the temperature range between 303.15 and 323.15 K and at atmospheric pressure. Excess molar volumes and viscosity deviations were calculated at various temperatures. Both excess molar volumes and the viscosity deviations are negative for all investigated systems. The isothermal excess molar volumes and viscosity deviations were fitted to a Redlich−Kister type equation, and the kinematic viscosity data were correlated with the McAllister equation.read more

The viscosity of liquid mixtures
TL;DR: The theory of viscosity of liquid mixtures presented in this article is based on Eyring's theory of absolute reaction rates, and the most important conclusions drawn are that for liquids the free energies of activation for visosity are additive on a number fraction or mole fraction basis and that interactions of like and unlike molecules must be considered.
