Abstract
A process for producing an alpha-halogeno-beta-aminopropionitrile which comprises reacting an alpha,beta-dihalogenopropionitrile with ammonia in water and/or an organic solvent. Action of a mineral acid on the reaction product gives a mineral acid salt of an alpha-halogeno-beta-aminopropionitrile. An isolated alpha-halogeno-beta-aminopropionitrile and a sulfate thereof are also provided.
