    Abstract: Method for producing and purifying 3-aminopropanolAbstractThe present invention relates to a process for purifying a reaction output which comprises 3- aminopropanol and is obtained in the reaction of ethylene cyanohydrin with hydrogen In the presence of ammonia, which comprises distilling the reaction output comprising 3- aminopropanol in two or more stages the ammonia content of the reaction output comprising 3- aminopropanol before Introduction into the first distillation stage being 1% by weight or less andthe temperature in the distillation stages being not more than 135°C.The invention further relates to a process for preparing 3-aminopropanol by reacting ethylene cyanohydrin with hydrogen in the presence of ammonia, which comprises performing the purification of the reaction output comprising 3-aminopropanol in accordance with the invention. The present invention further provides a process for preparing 3-aminopropanol derivatives,especially panthenol, acambrosate, mefenorex, domperidon, ifosamid or urapidil, from 3-amino propanol prepared In accordance with the invention.
