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-dihalo- geno-propionitrile or an alpha-halogenoacrylonitrile with ammonia, and is hydrolysed with a mineral acid without prior isolation of the alpha-halogeno-beta-aminopropionitrile therefrom.
α-卤代-beta-丙
氨酸或其矿物酸盐是通过α-卤代-beta-
氨基
丙腈或其矿物酸盐与矿物酸
水解制得的。在一个优选的实施方案中,起始材料是通过α,β-二卤代-属
丙腈或α-卤代
丙烯腈与
氨反应得到的,并与矿物酸
水解,而不事先从其中分离出α-卤代-β-
氨基
丙腈。
