Interpretive Summary:

Technical Abstract: A refined soybean oil with a nominal fatty acid composition of 54% linoleic acid, 24% oleic acid, 12% palmitic acid, and 5% linolenic acid was hydrogenated with a commercial nickel catalyst at pressures ranging from 50 psig to 500 psig. The triglyceride composition of the reaction mixture was determined by high pressure liquid chromatography over the course of the hydrogenation reactions. These data provided estimates for the selectivities of particular triglycerides which exhibited a dependence on hydrogen pressure. Possible reaction pathways for the hydrogenation of the triglycerides are presented and the effect of hydrogenation pressure on product distribution is discussed.
