    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: The invention relates to a method for isolating methyl glycine nitrile-N,N-diacetonitriles (MGDN) from an MGDN-containing aqueous emulsion with an MGDN content of 3 - 50% by weight in a crystallizer. The inventive method is characterized by (a) cooling the aqueous emulsion, starting from a temperature above the solidification point, to a temperature below the solidification point, the cooling rate in the temporal mean not exceeding 5 K/h, until substantially the total amount of the emulsified MGDN has solidified; and (b) continuing to cool the aqueous suspension obtained and/or concentrating it, the cooling rate being higher than that in step (a).

    Abstract: The invention relates to a method for producing an ethyleneamine mixture, wherein an aminonitrile mixture containing at least 30 wt. % aminoacetonitrile (AAN) and at least 5 wt. % iminodiacetonitrile (IDAN) is hydrogenated in the presence of a catalyst. Ethylenediamine (EDA) and/or diethylenetriamine (DETA) and optionally further ethyleneamines can be isolated from the resulting ethyleneamine mixtures.

    Abstract: The invention relates to a method for producing 3-cyano-3,5,5- trimethylcyclohexanone (isophorone nitrile) by reacting isophorone with hydrogen cyanide in the presence of a base as a catalyst. A special sulfonic acid or a special carboxylic acid is added to the resulting raw isophorone nitrile product which is then distilled. The invention further relates to the use of a special sulfonic acid or a special carboxylic acid as a neutralizing agent prior to distilling a raw isophorone nitrile product which is obtained by reacting isophorone with hydrogen cyanide in the presence of a base as a catalyst in order to prevent precipitations during neutralization of the base used as a catalyst with an acid.
