已推导出用于估计和预测正构脂肪酸及其酯的物理性能与碳数关系的经验方程。随着同系物中亚甲基数目的增加,其物性呈规则变化。很多人研究过脂肪酸及其衍生物的物理性质之一的粘度,发现它是绝对温度的指数函数。此外,饱和脂肪酸粘度的对数与分子量约成线性关系,但此线性关系并不是在整个范围内有效。Berchiesi 等测定了一系列正构脂肪酸在 Empirical equations have been derived for estimating and predicting the relationship between the physical properties and the carbon number of n-fats and their esters. As the number of homologues in the methylene increases, the physical properties of a regular change. Many people have studied the viscosity of one of the physical properties of fatty acids and their derivatives and found it to be an exponential function of absolute temperature. In addition, the logarithm of saturated fatty acid viscosity and molecular weight is approximately linear, but this linear relationship is not valid over the entire range. Berchiesi et al. Determined a series of n-fats
