Densities and viscosities for binary mixtures of butylamine with aliphatic alcohols

Densities and viscosities were measured for the binary mixtures of butylamine with 1-butanol, 1-pentanol, 1-hexanol, 1-heptanol, and 1-octanol at 303.15 K, 313.15 K, and 323.15 K over the entire composition range. Excess molar volumes and viscosity deviations were calculated at various temperatures. Both excess molar volumes and viscosity deviations are negative for all investigated systems. A Redlich-Kister type equation was applied to fit the isothermal excess volumes and viscosity deviations, and McAllister's three-body and four-body interaction models were also used to correlate the kinematic viscosities.
