Viscosities and Densities for Binary Mixtures of Benzylamine with 1-Pentanol, 2-Pentanol, 2-Methyl-1-butanol, 2-Methyl-2-butanol, 3-Methyl-1-butanol, and 3-Methyl-2-butanol

Viscosities and densities were measured for the binary mixtures of benzylamine with 1-pentanol, 2-pentanol, 2-methyl-1-butanol, 2-methyl-2-butanol, 3-methyl-1-butanol, and 3-methyl-2-butanol at temperatures from 298.15 K to 308.15 K. A pycnometer and Cannon−Fenske routine viscometer were used to determine density and kinematic viscosity, respectively. The calculated excess molar volumes V E and viscosity deviations δη for each binary system were found to be negative over the whole range of mixture compositions. Redlich−Kister type equations were fitted to the isothermal excess molar volumes and viscosity deviations, and the kinematic viscosity data were correlated with the McAllister equation.
