    • The present invention relates to a method for producing N,N-substituted-3-aminopropan-1-ols by a) converting secondary amine with acrolein at a temperature of (-50) to 100°C and a pressure of 0.01 to 300 bar, and b) converting the reaction mixture obtained in step a) with hydrogen and ammonia in the presence of a hydrogenation catalyst at a pressure of 1 to 400 bar, characterized in that in step a) the molar ratio of secondary amine to acrolein is 1:1 or more and the temperature in step b) is in the range of (-50) to 70°C. In a preferred embodiment, an acrolein that was obtained from glycerine based on renewable raw materials is used. The invention further relates to the use of an N,N-dimethyl-3-aminopropan-1-ol (DMAPOL) based on renewable raw materials as a catalyst for producing polyurethane, as a scrubbing liquid in gas scrubbing, in the field of electronics chemicals and electroplating, as a feed material in organic synthesis, and as an intermediate product in the production of pharmaceuticals and plant protection agents.
