ABSTRACT:
A process for preparing 2-amino-1-butanol by reacting L-tartarate of 2-amino-1-butanol with an aqueous slurry alkaline earth metal compound in such a way that some L-tartarate of 2-amino-1-butanol remains in the reaction system throughout the entire time of reaction to produce a precipitate of L-tartarate of the alkaline earth metal which comprises crystals which are sufficiently large so that they have excellent filterability and give a high yield of 2-amino-1-butanol. Highly purified 2-amino-1-butanol can be obtained by subjecting the thus obtained filtrate to rectification.
