Abstract

The gas chromatographic analysis of glycidol esters and mono-, di-,and triglycerides of palmitic-, stearic-, and oleic acid mixtures is described. The composition of the products was determined by gas chromatography on OV-17 after trimethylsilylation. Base-line separations between 1- and 2-monoglycerides and between 1,2- and 1,3-diglycerides were obtained. Isomerisation of the trimethylsilyl ethers of monoglycerides was not observed, contrary to published work.

摘要

描述了对缩水甘油酯以及棕榈酸、硬脂酸和油酸混合物的单甘油酯、二甘油酯和三甘油酯的气相色谱分析。产物组成通过三甲基硅烷化后在OV - 17上进行气相色谱测定。获得了1 - 单甘油酯和2 - 单甘油酯之间以及1,2 - 二甘油酯和1,3 - 二甘油酯之间的基线分离。与已发表的工作相反，未观察到单甘油酯的三甲基硅烷基醚的异构化。
