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.
