    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.
