<p num="1"><br/><br/><br/> ABSTRACT<br/> Amino acids having utility as intermediates<br/>in the production of a range of agricultural and<br/>pharmaceutical chemicals can be produced from suitable<br/>tertiary and secondary amines by dealkylation using<br/>an alkali metal hydroxide. The dealkylation process<br/>involves the production of primary and secondary amines<br/>by reacting, at a temperature of from 250°C to 400°C,<br/>an amine having groups containing an acidic function<br/>promoting solubility of the amine in aqueous alkaline<br/>solution and containing at least one acidic -OH group;<br/>with an aqueous alkali in at least the stoichiometric<br/>amount of alkali needed to neutralize the acidic -OH<br/>groups, so as to produce a compound in which the group<br/>R3 has been replaced by hydrogen.<br/><br/>
