ABSTRACT:
The present invention relates to a process for the production of primary amines containing aliphatically or cycloaliphatically bound amino groups, characterized in that the isocyanate groups of organic isocyanates containing aliphatically and/or cycloaliphatically bound isocyanate groups are formylated with formic acid in a first reaction step and the N-formyl groups are subsequently converted into amino groups.
The present invention also relates to polyamine mixtures obtained by this process and containing
