The catalytic activity and selectivity for hydrogenation of linoleic acid were studied on Ni, Cu, and Pd catalysts. A detailed analysis of the reaction product was performed by a gas‐liquid chromatograph, equipped with a capillary column, and Fourier transform‐infrared spectroscopy. Geometrical and positional isomerization of linoleic acid occurred during hydrogenation, and many kinds of linoleic acid isomers (
The isomerization that takes place during the catalytic hydrogenation of linoleic acid and methyl linoleate produces
Although the degree of selectivity of the hydrogenation is determined by the amount of isomerization of the original pentadiene system to a conjugated diene, only part of the methylene‐interrupted diene goes through this type of isomerization even during a highly selective hydrogenation.
The half hydrogenation‐dehydrogenation reaction mechanism is applied to explain the simultaneous positional and geometrical isomerizations.
