    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: Prepn. of 2,2-disubstd. pentane-1,5-diamines of formula (I) is claimed, some of which are claimed as novel cpds.. The prepn. of (I) is from 2,2-disubstd.-4-cyano-butanals of formula (II) by reaction in two separate zones such that (i) (II) is treated at 20-150 deg.C/15-500 bar with an excess of ammonia in presence of an acidic heterogeneous catalyst in a first reaction zone; and (ii) the prod. of step (i) is treated in a second reaction zone at 60-150 deg.C/50-500 bar with H2 in presence of an excess of ammonia using a Co-, Ni-, Ru and/or other noble metal-contg. catalyst opt. with basic components or on a basic or neutral carrier. In the formulae, R1 and R2 = are each. 1-10C alkyl or 2-10C alkenyl or together form a 4-7C alkylene chain opt. substd. by one to five 1-4C alkyl gps.. The novel claimed cpds. are of formula (I) with the proviso that R1 and R2 are not simultaneously Me, specifically claimed novel cpds. being 2-Me-2-n-propylpentane-1,5-diamine; and 2-nBu-2-ethylpentane- 1,5-diamine. USE/ADVANTAGE - On account of their high degree of substn., (I) are distinguished by (a) their reduced volatility in comparison to 2-Me- and 2,2-di-Me-pentanediamines and (b) their asymmetric amine functionality. (I) show low odour and can be converted to diisocyanates. (8pp Dwg.No.0/0)
