FIELD: organic chemistry.
SUBSTANCE: target products is produced by ethylene diamine transamination. Reaction is carried out at 135-180°C at pressure of 5-40 MPa in presence of hydrogen and catalyst particles containing 26-65 wt.% of metallic nickel on porous carrier.
EFFECT: high ethylene diamine conversion ratio and high selectivity in relate to target acyclic polyethylene polyamines under advantageous reaction conditions.
