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.
含有8-12个碳原子的ω-氨基烯酸可通过在氢化催化剂存在下将含有8-12个碳原子的ω-甲酰基烯酸与氨和氢反应而得到。最好的情况是通过将多不饱和碳氢化合物环烯与臭氧反应以形成单臭氧化物溶液,并以极性溶剂的形式存在于可分离相中,该溶液可以转换为起始的ω-甲酰基烯酸。
