Abstract

N-brominated cyanuric acid is prepared by treating cyanuric acid with bromine in an aqueous alkaline solution, and, before, during or after this treatment, introducing chlorine, an alkali hypochlorite, or N-chlorocyanuric acid. An example treats cyanuric acid in aqueous NaOH solution with bromine and then with chlorine.ALSO:An N-brominated organic compound is prepared by treating a compound selected from cyclic imides of aliphatic or benzene dicarboxylic acids, saturated aliphatic amides, hydantoins, benzene sulphonamides, melamine and cyanuric acid with bromine in an aqueous alkaline solution and, before, during or after this treatment, introducing chlorine, an alkali hypochlorite, or the corresponding N-chloro organic compound. Examples prepare (1)-(4) N-bromosuccinimide, (5) N-bromophthalimide, (6), (7) N-bromoacetamide, (8) 1,3-dibromo-5-ethyl-5-methylhydantoin, (9)-(11) 1,3-dibromo-5,5-dimethylhydantoin, (12) monobromo-5,5-dimethylhydantoin, (13) N,N-dibromobenzenesulphonamide, (14) N-brominated cyanuric acid, (15) tribromomelamine, and (16) hexabromomelamine.
