Title:
SELECTIVE HYDROGENATION OF UNSATURATED FATTY ACID DERIVATIVES
Document Type and Number:
Japanese Patent JPS5639038
Kind Code:
A
Abstract:
Triglyceride oils, which contain besides fatty acids having two double bonds, fatty acids having more than two double bonds, are hydrogenated using palladium, platinum, rhodium and/or iridium as a catalyst, the catalyst being treated with dry ammonia. The hydrogenation is carried out at a temperature of at least 100 DEG C. The hydrogenation progresses in a particularly selective manner. On using, for instance, soyabean oil, which contains about 55% of linoleic acid and 7% of linolenic acid, the amount of linolenic acid can be reduced to 2%, whereby more than 45% of linoleic acid is retained in the hydrogenated product. In case the catalyst is not treated, said amount is only about 35%.
