Method for producing and purifying 3-aminopropanol

摘要

Purifying a reaction output which comprises 3-aminopropanol obtained by reacting ethylene cyanohydrin with hydrogen in the presence of ammonia, comprises distilling the reaction output in at least two stages, where the ammonia content of the reaction output before introduction into the first distillation stage is = 1 wt.% and the temperature in the distillation stages is = 135[deg] C.
