<p>THE PRESENT INVENTION RELATES TO A PROCESS FOR PREPARING N,N-SUBSTITUTED 3-AMINOPROPAN-1-OLS BY A) REACTING SECONDARY AMINE WITH ACROLEIN AT A TEMPERATURE OF (-50) TO 100°C. AND A PRESSURE OF 0.001 TO 30 MPA (0.01 TO 300 BAR), AND B) REACTING THE REACTION MIXTURE OBTAINED IN STAGE A) WITH HYDROGEN AND AMMONIA IN THE PRESENCE OF A HYDROGENATION CATALYST AT A PRESSURE OF 0.1 TO 40 MPA (1 TO 400 BAR), WHEREIN THE MOLAR RATIO OF SECONDARY AMINE TO ACROLEIN IN STAGE A) IS 1:1 OR MORE AND THE TEMPERATURE IN STAGE B) IS IN THE RANGE FROM (-50) TO 70°C. IN A PREFERRED EMBODIMENT, ACROLEIN WHICH HAS BEEN OBTAINED FROM GLYCEROL 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 POLYURETHANE PREPARATION, AS A SCRUBBING FLUID IN GAS SCRUBBING, IN THE ELECTRONICS CHEMICALS AND ELECTROPLATING SECTORS, AS A FEEDSTOCK IN ORGANIC SYNTHESIS, AND AS AN INTERMEDIATE IN THE PRODUCTION OF PHARMACEUTICALS AND CROP PROTECTION COMPOSITIONS.</p> |
