Abstract (en)
[origin: WO2006082203A1] The invention relates to a method for producing bis-[(3-dimethylamino)propyl]amine (dipropylene triamine, DPTA) by continuously reacting 1,3-propylene diamine (1,3-PDA) in the presence of a heterogeneous catalyst. The inventive method is characterized by carrying out the reaction in a reaction column.
