Abstract

Aliphatic o -aminocarboxylic acids containing more than two methylene groups are prepared by treating the corresponding hydrochlorides with liquid ammonia and allowing the loose ammonia-o -aminocarboxylic acid addition compounds so formed to decompose at reduced or room temperature or under the application of heat. o -Aminocarboxylic acid hydrochlorides or mixtures thereof with ammonium chloride derived by hydrolysis of the corresponding o -aminonitriles or of the hydrochlorides of the corresponding amino-nitrilium compounds may be used. The amino-nitrilium compounds may in turn be derived from corresponding o -aminonitriles by treatment with dry hydrogen chloride, and the o -aminonitriles may be obtained from o -chloronitriles by reaction with ammonia. If desired the above process may be conducted continuously and any ammonium chloride formed as a by-product may be treated with brine to generate ammonia. The ammonia treatment is preferably carried out at temperatures ranging from -30 DEG C. to -45 DEG C., or from 0 DEG C. to room temperature under elevated pressure. After decomposition of the ammonia-o -aminocarboxylic acid addition compound at elevated temperatures, the resulting solid o -aminocarboxylic acid is preferably subjected at room temperature to a further treatment with liquid ammonia and/or a treatment with water, alcohols or aliphatic or aromatic hydrocarbons or mixtures thereof. Examples describe the recovery of e -aminoenanthic, o -aminopelargonic, o -aminoundecanic, o -aminopentadecanic and d -aminovaleric acids. Specification 907,325 is referred to.
