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 average absolute percentage deviations of 0.04 and 0.83%, respectively. The excess molar volumes and viscosity deviations show positive and negative deviations from 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-Ríos equation correlates the kinematic viscosity within 0.88%.

（288.15至338.15）K在0.1 MPa下的生物柴油+ 1-戊醇，2-戊醇或2-甲基-1-丁醇的二元液体混合物的密度和粘度
这项工作介绍了在0.1 MPa下与288.15至338.15 K之间的1-戊醇，2-戊醇和2-甲基-1-丁醇混合的生物柴油的实验测定密度和粘度。使用振动管密度计测量密度，并使用玻璃毛细管粘度计测量运动粘度。纯组分的测得密度和粘度分别与文献中报道的值相符，分别在0.04和0.83％的平均绝对百分比偏差之内。过量的摩尔体积和粘度偏差分别显示出与理想值的正偏差和负偏差。Redlich–Kister方程用于表示过量摩尔体积和粘度偏差的组成行为。在50-90％（重量）酒精的组成范围内，实验运动粘度具有最小值。
