Abstract
b -Aminopropionic acid is prepared by reacting aqueous solutions of ammonia with ethylene cyanhydrin. The product is worked up by concentrating to a syrup and precipitating by adding methanol. By reacting with a further quantity of ammonia, the filtrate yields further quantities of aminoacid. In examples, ethylene-cyanhydrin is reacted with various concentrations of ammonium hydroxide. The use of corrosion inhibitors and ammonium salts of a weak acid in the process is mentioned. The Specification as open to inspection under Sect. 91 comprises also the preparation of aliphatic amino acids in general from cyanhydrins and ammonia or aliphatic amines. Alkylolamines are mentioned. This subject-matter does not appear in the Specification as accepted.
