The invention relates to 2,6-bis-(aminomethyl)piperidine derivates themselves ("2,6-BAMP derivatives" for short henceforth), which are defined by the general formula (I) specified below. The invention additionally relates to a method for producing such 2,6-BAMP derivatives by hydrogenating the corresponding 2,6 dicyanopiperidine derivatives ("2,6-DCP derivatives" for short henceforth) in the presence of a catalyst. The invention further relates to the use of the 2,6-BAMP derivatives according to the invention as a curing agent for epoxy resins, as an intermediate product in the production of diisocyanates, which play an important role in the production of polyurethanes, as a starter in the production of polyetheroles, and/or as a monomer for producing polyamide. The invention further relates to the diisocyanates themselves produced from the 2,6-BAMP derivatives and to the corresponding production method. |
