FIELD: chemistry.
SUBSTANCE: invention concerns a purification method for aliphatic diamines obtained by hydration of dinitrile compounds. The method involves an additional stage of diamine hydration in the presence of a catalyst containing an element from platinum, palladium, ruthenium, rhodium, iridium, nickel and cobalt group.
EFFECT: enables elimination of admixtures.
