Process for producing alpha-halogeno-beta-alanines or the mineral acid salts thereof.

摘要

Alpha-halogeno-beta-alanines or the mineral acid salts thereof are produced by hydrolyzing alpha-halogeno-beta-aminopropionitriles or the mineral acid salts thereof with mineral acids. In a preferred embodiment the starting material is obtained by the reaction of an alpha,beta-dihalogeno-propionitrile or an alpha-halogenoacrylonitrile with ammonia, and is hydrolysed with a mineral acid without prior isolation of the alpha-halogen-beta-aminopropionitrile therefrom.
