    Abstract: 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.

    Abstract: What is proposed is a process for preparing a crystalline L-MGDA tri-alkali metal salt by crystallization from an aqueous solution thereof which has been obtained by Strecker synthesis proceeding from L-α-alanine, by reaction with formaldehyde and hydrogen cyanide to give L-α-alanine-N,N-diacetonitrile and subsequent alkaline hydrolysis of the L-α-alanine-N,N-diacetonitrile to give the L-MGDA tri-alkali metal salt, which is characterized in that a temperature of 150°C is not exceeded in the course of alkaline hydrolysis.

    Abstract translation: 所提出的是一种制备结晶L-MGDA三碱金属盐的方法,该方法是通过从由Strecker合成从L-α-丙氨酸进行的水溶液中结晶,通过与甲醛和氰化氢反应得到L -α-丙氨酸-N,N-二乙腈,随后碱性水解L-α-丙氨酸-N,N-二乙腈,得到L-MGDA三碱金属盐,其特征在于温度为150℃ 在碱性水解过程中不超过。
