This work presents experimentally determined densities and viscosities of biodiesel blended with 1-pentanol, 2-pentanol, and 2-methyl-1-butanol between 288.15 and 338.15 K at 0.1 MPa. The densities are measured using a vibrating tube densimeter, and the kinematic viscosities using a glass capillary viscometer. The measured density and viscosity of the pure components agree with values reported in the literature within an average absolute percentage deviation of 0.04 % and 0.83 %, respectively. The excess molar volumes and viscosity deviations show positive and negative deviations from the ideality, respectively. The Redlich-Kister equation is used to represent the composition behavior of the excess molar volumes and viscosity deviations. The experimental kinematic viscosities have a minimum value over a composition range of 50-90 % alcohol by weight. The McAllister equation correlates the kinematic viscosity within an average absolute percentage deviation of 1.77 %, while the Nava-Rios equation correlates the kinematic viscosity within 0.88 %.
