Abstract: Process for the preparation of 2-(3-aminopropyl)cycloalkylamines of the general formula I in which the index n is an integer from 1 to 4, from 2-(2-cyanoethyl)cycloalkanones of the general formula II in which the index n has the abovementioned meaning, by carrying out the following steps in two reaction spaces spatially separated from one another: a) reacting the 2-(2-cyanoethyl)cycloalkanones of the formula II in a first reaction space with excess ammonia over acidic heterogeneous catalysts at temperatures of 20 to 150 DEG C and pressures of 15 to 500 bar and b) hydrogenating the reaction products 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 100 to 500 bar, and also the novel compound 2-(3-aminopropyl)cyclopentylamine.

Abstract: Caprolactam is prepared by heating a 6-aminocaproic ester in liquid phase in the presence of water to 230 DEG -350 DEG C. under superatmospheric pressure in a reaction medium comprising a liquid aromatic hydrocarbon having a boiling point of from 80 DEG to 240 DEG C. which is inert under reaction conditions, and isolating caprolactam from the reaction mixture.

Abstract: In the purificn. of caprolactam (I) by oxidative treatment, mixts. of (I) and unsatd. lactams (II) are treated with (a gas mixt. contg.) O2 in alkaline medium. Treatment is carried out with air and in the presence of an alkali(ne earth) metal (hydr)oxide. USE/ADVANTAGE - (I) is used in polyamide-6 mfr. (II) are eliminated without causing disposal problems, e.g. by formation of MnO2 if KMnO4 is used as oxidant.
