Abstract

We report measurements of absolute saturation vapor pressures around room temperature for three fatty acid methyl esters (methyl octanoate, methyl decanoate, and methyl dodecanoate) using a recently developed experimental method in which the saturation vapor pressures are determined from the vaporization dynamics of a cooled sample during thermalization to a higher chamber temperature.

摘要

我们报告了使用一种最新开发的实验方法对三种脂肪酸甲酯（辛酸甲酯、癸酸甲酯和十二酸甲酯）在室温附近的绝对饱和蒸气压进行的测量。在该方法中，饱和蒸气压是根据冷却样品在热平衡至更高腔室温度期间的汽化动力学来确定的。
