in the reported experiments, the hydrogenation of cyclopropenoid acids and their relative reactivities during hydrogenation as compared to linoleic and oleic acids were examined nickel, palladium and platinum catalysts were used. the effect of temperature and type of catalyst were demonstrated in a series of hydrogenation experiments of safflower and s. foetida oil mixtures, and methyl oleate and methyl dihydrosterculate mixtures. the cyclopropene group hydrogenated very readily compared to the 9, 12-diene system in linoleate. the cyclopropane group obtained by hydrogenating the cyclopropenoid acids group was quite resistant to further attack by hydrogen and nickel catalyst had little effect with palladium catalyst, a temperature of 180 $degree$ c was necessary for the reaction to go to completion. platinum in acetic acid was a good system for hydrogenolysis of the cyclopropane group at 80 c. 18 refs
