ABSTRACT DESCRIPTION The present invention relates to a hydro-chemical catalytic lysis of .alpha.-amino-nitriles or their salts. According to the method of the invention, a aqueous solution containing at least one carbonyl derivative on the says .alpha.-amino-nitrile or on one of its salts in the presence of ions hydroxides. For the preparation of .alpha.-amino acids we introduce OH- ions in the reaction medium, so as to reach substantially the equimolarity of the hydroxide with respect to the alpha. starting amino-nitrile. |
