Photochemical decomposition of phenazone derivatives. Part 5(1): Isolation and identification of decomposition products in aqueous solution.
From aqueous solutions of phenazone, aminophenazone, propyphenazone, nifenazone, morazone, noramidopyrine, 4-aminophenazone and isopropylaminophenazone, UV irradiated at lambda = 254 nm in oxygen free atmosphere as well as in the presence of air, 24 decomposition products were isolated and identified as derivatives of pyrazoline, pyrazolidinone, imidazoline, hydantoin, aziridine, phenylhydrazine and aniline.
