Abstract

Studies have been made on the conjugated hydrogenation of peanut and safflower oils using nickel catalyst and with alcohols as hydrogen donors. Peanut oil was reduced with ethyl alcohol to a final iodine value of 64–71 and the reaction is selective because little saturated acid is formed but some linoleic acid is retained. When the same oil is reduced with isopropyl or secondary butyl alcohols an iodine value of ∼25 is reached while all linoleic acid has disappeared. With safflower oil and isopropyl alcohol an iodine value of ∼46 is reached and the reaction is selective since all linoleic acid has disappeared. Thus the amount of monoene retained depends on initial unsaturation of the oil when a secondary alcohol is used as hydrogen donor.
