| titleOfInvention | Process for producing N, N-substituted-1,3-propanediamine |
| abstract | The invention comprises a) reacting the secondary amine with acrolein at a temperature between (-50) and 100 ° C. and a pressure between 0.01 and 300 bar, and b) a temperature between 40 and 400 ° C. Process for producing N, N-substituted-1,3-propanediamine by reacting the reaction mixture obtained in step a) with hydrogen and ammonia at a pressure of 1 to 400 bar in the presence of a hydrogenation catalyst About. The invention is characterized in that in step a) the molar ratio of secondary amine to acrolein is 2: 1 or more and that the hydrogenation catalyst used in step b) contains cobalt. In a preferred embodiment, acrolein obtained from glycerin based on renewable raw materials is used. The present invention also relates to the use of N, N-dimethyl-1,3-propanediamine (DMAPA) based on renewable raw materials as charge materials for soft soaps and other detergents, flocculants, polymers and comb polymers Also related. In another preferred embodiment, step b) is performed in the presence of water. |
