Determination of epoxy groups in the presence of carboxylic acids of the acryl series and aromatic amines

Selective reactions for the determination of epoxy groups in the presence of acrylic acids and aromatic amines were studied. Factors affecting results of the determination of epoxy groups were revealed. Procedures were developed for the determination of epoxy and carboxylic groups and epoxy and amine (aromatic) groups in the presence of each other. The reaction is conducted in excess HCl in the former case and in excess tetraethylammonium bromide in the latter case. Performance characteristics of the procedures were estimated.
