The invention relates to 3-amino-4-aminomethyl-pyrrolidines which contain, in the 1-position of the heterocyclic ring, organic radicals as substituents, and in which also the H-atom in the 2-position of the heterocyclic ring can be substituted by an organic radical. The invention also relates to the preparation of these pyrrolidines by catalytic hydrogenation of the corresponding 3-amino-4-cyano-3-pyrrolines. Hydrogenation is preferably performed in the presence of NH.sub.3. The amines according to the invention are suitable as curing agents for epoxide resins, as reactants for isocyanates, and as starting substances for polyamides.
该发明涉及3-氨基-4-氨甲基-吡咯烷,其在杂环环的1-位置含有有机基作为取代基,在杂环环的2-位置的H原子也可以被有机基取代。该发明还涉及通过催化氢化相应的3-氨基-4-氰基-3-吡咯烯制备这些吡咯烷。氢化最好在NH.sub.3存在下进行。根据该发明的胺类适用作为环氧树脂的固化剂,作为异氰酸酯的反应物,以及作为聚酰胺的起始物质。
