In this work, surface tensions, densities, viscosities, and refractive indices of biodiesel +1-hexanol, 4-methyl-2-pentanol, and 2-ethyl-1-butanol have been measured from 288.15 to 338.15 K at 0.1 MPa throughout the whole composition range. Du Noüy ring tensiometer, vibrating tube densimeter, glass capillary viscosimeter, and Abbemat refractometer are used to measure the surface tensions, densities, viscosities, and refractive indices, respectively. Our experimental results for the pure alcohols agree with literature values within average absolute percentage deviations of 1.171, 0.024, 0.737, and 0.061 % for the surface tension, density, viscosity, and refractive index, respectively. Experimental densities and viscosities of some of our biodiesel mixtures satisfy the limits set by the diesel fuel standard (EN 590), becoming potential substitutes of conventional diesel. Kinematic viscosities show a minimum value at alcohol mass fractions between 0.4 and 0.9. Thermodynamic properties and derived properties have been correlated using different equations reported in the literature.

生物柴油与己醇异构体共混物在不同温度下的物理性质：表面张力，密度，粘度和折射率
在这项工作中，生物柴油+ 1-己醇，4-甲基-2-戊醇和2-乙基-1-丁醇的表面张力，密度，粘度和折光率在整个过程中以0.1 MPa从288.15至338.15 K进行了测量。整个组成范围。DuNoüy环形张力计，振动管密度计，玻璃毛细管粘度计和Abbemat折光仪分别用于测量表面张力，密度，粘度和折射率。我们的纯醇实验结果与文献值相符，表面张力，密度，粘度和折射率分别在1.171％，0.024％，0.737％和0.061％的平均绝对百分比偏差内。我们某些生物柴油混合物的实验密度和粘度满足柴油标准（EN 590）设定的极限，成为常规柴油的潜在替代品。运动粘度在0.4至0.9的醇质量分数下显示出最小值。已经使用文献中报道的不同方程式将热力学性质和衍生性质相关联。
