Patent abstract
An amine of the formula (I) and a process for its preparation by reductive alkylation of 1,2-propylenediamine with a di- or trifunctional carbonyl compound and hydrogen. The amine of the formula (I) is low in viscosity and in odour, high in reactivity towards epoxides and outstanding in its compatibility with other amines and with epoxy resins. The amine of the formula (I) allows access to low-emission epoxy resin compositions which have good processing qualities, cure rapidly even at low temperatures and form high-quality, high-hardness plastics having an attractive surface.
