    Abstract: 3-( gamma -aminopropyl)-piperidines can be manufactured by hydrogenating certain bis-cyanoethylated aldimines in the presence of a catalyst and preferably in the presence of an organic solvent. The hydrogenation can be executed at temperatures up to 200*C either without application of pressure or under pressure. Cyclisation occurs with a primary amin being split off. The piperidine derivatives, obtainable according to this invention are suitable as curing agents for epoxy resins.

    Abstract: The new compound 5-amino-2-( Beta -cyanoethyl)-5-cyclohexen-1one is manufactured by cyclisation of certain bis-cyanoethylated diketones at temperatures between 40* and 250*C in the presence of a basic catalyst and of an organic solvent. A prefered starting substance is 3,3-bis-( Beta -cyanoethyl)-pentane-2,4dione. This product can be obtained by cyanoethylation of acetylacetone in the presence of base. The new cyclic ketone 5amino-2-( Beta -cyanoethyl)-5-cyclohexen-1-one represents a valuable intermediate product for the manufacture of 7-aminodecahydro-quinoline.

    Abstract: The new 7-amino-decahydro-quinolines are manufactured by hydroxygenating 5-amino-2-( Beta -cyanoethyl)-5-cyclohexen-1-one in a manner which is in itself known. The 5-amino-2-( Beta cyanoethyl)-5-cyclohexen-1-ones used as the starting substances can be obtained by several reactions, which are disclosed by several publications. One reaction is the cyclisation of cyanoethylated aliphatic ketones in the presence of suitable catalysts. The new 7-amino-decahydro-quinolines represent valuable curing agents for epoxide resins and advantageously 0,5 to 1,3 equivalents of nitrogen-bonded active hydrogen atoms of the 7-amino-decahydro-quinolines are used per 1 equivalent of epoxide groups of the polyepoxide compound.
