It was found that during the hydrogenation of octadecenoic acids, migration of the double bonds takes place equally in each direction. The positional isomers that are formed are composed of the 1∶2 equilibrium mixture ofcis andtrans. A partial hydrogenation-dehydrogenation theory may be applied to explain the simultaneous formation of both positional and geometrical isomers.
