酸素存在下におけるテオフィリン水溶液中での脂肪族ジアミンの光安定性

The photo-stability and the structures of photo-oxidation products of ethylenediamine and propylenediamine in aqueous solutions with or without theophylline were investigated. Formaldehyde formed from ethylenediamine and propylenediamine, and acetaldehyde from propylenediamine were characterized as 2, 4-dinitrophenylhydrazones. Glyoxal formed from ethylenediamine was characterized as glyoxime. It was found that photodegradation of ethylenediamine and propylenediamine was more rapid in aqueous solutions than in aqueous theophylline solutions.
