title: [On the reaction of chlorine, bromine, iodine and some N-chloro and N-bromo compounds with peptone in aqueous solution (author's transl)].
abstract: The course of the reaction cited in the heading was investigated by determination of the decrease of iodometrically ascertainable oxidation capacity (pH = 7,00; initial concentration: 5 X 10(-3) M active Halogen/1, 0,5 g peptone/1). From the curves depicted in fig. 1 the following scale of reactivity can be derived: dibromoisocyanuric acid greater than bromine greater than 1,3-dibromo-5,5-dimethylhydantoin greater than N-bromo-N'-chloro-dimethylhydantoin greater than clorine greater than trichloroisocyanuric acid greater than 1,3-dichloro-5,5-dimethylhydantoin greater than iodine greater than chloramine T. The reactivity differences tentatively are explained by electronic, kinetic resp. thermodynamic effects.
