In the alkali-refining of rice oil by the usual procedure employed for cottonseed and similar oils excessive losses occur. A rice oil containing about 5% of free fatty acids may refine with a loss of over 40% by the cup method. A series of experiment

The hydrogenation of the oleic acid group was investigated with the objective of determining the effect of solvents on the reaction rate and the formation of positional and geometrical isomers. Methyl oleate, either alone or dissolved in one of sever

A commercial cottonseed oil was hydrogenated under nonselective, normal, and selective conditions. The operating variables used were within the ranges of those ordinarily found in large-scale operations. For each run samples were withdrawn at iodine

The degree of activity of Raney nickel catalysts in the hydrogenation of triglycerides has been found to vary considerably with and to depend upon unknown factors in the original alloy. Highly active preparations of Raney nickel rapidly lost their ac

The cyclopropene acid groups in cottonseed oil can be modified by a light hydrogenation which will not produce large amounts oftrans isomers or lower the iodine value to a significant extent. Optimum conditions, as indicated by this investigation, ar

Olive oil was hydrogenated to an iodine value (I.V.) of ca. 50 under widely differeing operating conditions. Three types of catalyst were employed. Each catalyst was used at the lowest possible operating temp and at 170C. The hydrogenated samples wer
