Abstract
Process for the preparation of diamines, particularly substituted pentandiamines, of the formula ** formula ** where R1 and R2, the same or different from each other, can be hydrogen, an aliphatic or cyclic aliphatic radical, R3 and R4 the same or different from each other, can be aliphatic or cycloaliphatic radicals, and R5 can be hydrogen, an aliphatic, cycloaliphatic or aromatic radical, characterized in that dinitriles of general formula ** formula ** are subjected to hydrogenation where R1, R2, R3, R4, R5 have the meaning above exposed.
