This paper presents densities and viscosities of binary mixtures of n-undecane with 1-propanol, 1-butanol, 1-pentanol, and 1-hexanol from 283.15 to 363.15 K at 0.1 MPa over the entire composition range. Densities come from a vibrating tube densimeter, while viscosities are from a pellet microviscometer. A three-body McAllister equation correlates the kinematic viscosities together with an equation based upon a quadratic mixing rule for the Gibbs energy of activation. The excess molar volumes and viscosity deviations calculated from the experimental data have positive and negative deviations from ideality over the temperature range, respectively.
