Abstract
An omega-amino alkenoic acid containing from 8 to 12 carbon atoms is obtad from an omega-formyl alkenoic acid, which also contains from 8 to 12 carbon atoms, by reacting the acid with ammonia and hydrogen in the presence of a hydrogenation catalyst. Preferably the omega-formyl alkenoic acid is obtained by reacting a polyunsaturated hydrocarbon cycloolefin with ozone to form a mono-ozonide in solution with a polar solvent, the solution being in the form of a separable phase which can be transposed to form the starting omega-formyl alkenoic acid.
