Process for the preparation of pyrrolidonecarboxylic acid/metal/amine complexes

Process for the preparation of pyrrolidonecarboxylic acid/metal/amine complexes

A process for the preparation of pyrrolidone-5-carboxylic acid/metal salt/amine complexes by reacting 1 mol of a L-glutamic acid lower alkyl ester/metal salt complex with 1 mol of an aliphatic, cycloaliphatic or aromatic-aliphatic damine or 2 mols of an aliphatic or cycloaliphatic monoamine in a pol...

description A process for the preparation of pyrrolidone-5-carboxylic acid/metal salt/amine complexes by reacting 1 mol of a L-glutamic acid lower alkyl ester/metal salt complex with 1 mol of an aliphatic, cycloaliphatic or aromatic-aliphatic damine or 2 mols of an aliphatic or cycloaliphatic monoamine in a polar solvent, with the elimination of 2 mols of alcohol. The complex compounds prepared according to the invention are valuable curing agents for epoxide resins.
