ABSTRACT Amino acids having utility as intermediates in the production of a range of agricultural and pharmaceutical chemicals can be produced from suitable tertiary and secondary amines by dealkylation using an alkali metal hydroxide. The dealkylation process involves the production of primary and secondary amines by reacting, at a temperature of from 250°C to 400°C, an amine having groups containing an acidic function promoting solubility of the amine in aqueous alkaline solution and containing at least one acidic -OH group; with an aqueous alkali in at least the stoichiometric amount of alkali needed to neutralize the acidic -OH groups, so as to produce a compound in which the group R3 has been replaced by hydrogen.
