Abstract: 1,3-Diamino-2,2-dialkylpropanes whose alkyl substituents are each of 1 to 4 carbon atoms are prepared by reacting the corresponding 2,2-dialkylpropane-1,3-diols with ammonia in the presence of hydrogen under superatmospheric pressure by a process in which the reaction is carried out in solution and in the presence of a cobalt-containing catalyst.

Abstract: N-Alkylpiperidines or N-alkylpyrrolidines are obtained by hydrogenating a corresponding N-alkyldicarboxylic acid imide over a fixed catalyst by first working to only partial conversion, for example of about 50%, and distilling off the required product together with water from the partially converted mixture, where appropriate with recycling of the unconverted remainder.

Abstract: 1-Alkyl- or 1-cycloalkylpiperazines are prepared by reacting piperazine with an alkanol or cycloalkanol in the presence of hydrogen and a hydrogenation/dehydrogenation catalyst by a process in which the reaction is carried out at from 130 DEG to 190 DEG C. under from 5 to 100 bar in the presence of from 5 to 40% by weight, based on the reaction mixture, of water, and the molar ratio of piperazine to alkanol or cycloalkanol is kept at from 1:1.5 to 1:8.
