ABSTRACT:
Amine salts of aromatic and aliphatic carboxylic acids are produced by hydrolysis of a corresponding nitrile, imide, amide or mixtures thereof in the presence of an amine, and stripping of evolved ammonia. The amine salts may be used in separation of certain isomeric acids, and are useful as intermediates in the production of the corresponding carboxylic acids and derivatives thereof, such as esters and anhydrides.
