Abstract

PURPOSE: To obtain an α-halogeno-β-alanine or its mineral acid salt, useful as an intermediate for the synthesis of α-amino acids such as serine or an intermediate for medicines, etc., in high yield, by the hydrolysis of a mineral acid salt of α- halogeno-β-aminopropionitrile.
CONSTITUTION: Minceral acid salts of α-halogeno-β-aminopropionitrile (e.g. α- chloro-β-aminopropionitrile hydrochloride, α-chloro-β-amino-propionitrile sulfate, etc) are added to a mineral acid (preferably hydrochloric acid or sulfuric acid) and subjected to hydrolysis, to obtain α-halogeno-β-alanine and mineral acid salts thereof. Concentration of the mineral acid used is, for example, preferably 8W 30wt% in the case of hydrochloric acid and 15W60wt% in the case of sulfuric acid.
EFFECT: Since the separation of the objective product from by-products is not necessary, the present process is industrially very advantageous.
