| Abstract: | Course of Reaction During Hydrogenation of Triglycerides — Simultaneous Hydrogenation of Tri- and Monolinolenin Mixtures of trilinolenin and dipalmitomonolinolenin were subjected to hydrogenation. Argentation chromatography resolved the reaction products into two fractions, each containing one of the starting materials and their hydrogenated products. The relative rate of hydrogenation of linolenic acid in both glycerides could be determined by gas chromatography of the transesterified fractions. It was possible to draw conclusions on the course of reaction using mathematical models for various reaction mechanisms, which have been derived earlier1. Considerable differences in the behaviour of different catalysts were observed. The results could be explained by assuming equal probability of binding of all the glycerides on the catalyst. Depending on the type of catalyst used, spontaneous hydrogenation of several linolenoyl moieties occurred to varying degree. |
