    Abstract: Process for the preparation of 3-aminomethyl-3,5,5-trimethylcyclohexylamine from 3-cyano-3,5,5-trimethylcyclohexanone by carrying out the following steps in two reaction spaces spatially separated from one another: a) reacting the 3-cyano-3,5,5-trimethylcyclohexanone in a first reaction space with excess ammonia over acid metal oxide catalysts at temperatures of 20 to 150 DEG C and pressures of 15 to 500 bar and b) hydrogenating the reaction products formed in a second reaction space with hydrogen in the presence of excess ammonia over cobalt-, nickel-, ruthenium- and/or other noble metal-containing catalysts which may contain basic components or are present on neutral or basic supports at temperatures of 60 to 150 DEG C and pressures of 50 to 300 bar.

    Abstract: Process for the recovery of caprolactam from polycaprolactam by hydrolytic cleavage of polycaprolactam with 5 to 50 parts by weight of water per part by weight of polycaprolactam at a temperature from 200 to 350 DEG C at elevated pressure with the production of an aqueous solution or suspension which contains monomeric caprolactam, its oligomer and optionally polycaprolactam and subsequent removal of monomeric caprolactam from the aqueous solution or suspension by distillation or extraction, the hydrolytic cleavage being carried out at a pH from 5 to 10 with the additional use of alkali metal hydroxide.

    Abstract: New 2,2-disubstituted pentane-1,5-diamines of formula H2N-(CH2)3-C(R1)(R2)-CH2NH2 (I) (in which R1 and R2 independently = 1-10C alkyl or 2-10C alkenyl or R1 and R2 together form a 4-7C alkylene chain which is opt. substd. by 1-5 1-4C alkyl gps), are prepd. from 2,2-disubstituted 4-cyano-butanals of formula NC-(CH2)2-C(R1)(R2)-CH=O (II) by (a) reacting the (II) in a first reaction chamber with excess ammonia over an a acidic heterogeneous catalyst at temps. of 20-150 deg.C and a pressure of 15-500 bar, and (b) hydrogenating the reaction prods. in a second reaction chamber with hydrogen in the presence of excess ammonia over Co-, Ni-, Ru- and/or other noble metal contg. catalysts, opt. with basic components or on basic or neutral carriers, at temps. of 60-150 deg. C and a press. of 50-500 bar. Pref. in (I) R1 and R2 are both both Me. Claimed cpds. (I) are 2-methyl-2-n-propyl- pentane-1,5-diamine (Ia), 2-n-butyl-2-ethyl-pentane-1,5-diamine (Ib) and 2-n-propyl-2-n-propyl-pentane-1,5-diamine (Ic).
