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.

摘要

通过测定碘量法可确定的氧化能力的降低（pH = 7.00；初始浓度：5×10⁻³ M活性卤素/1，0.5 g蛋白胨/1）来研究标题中所述反应的进程。从图1所示的曲线可以得出以下反应活性顺序：二溴异氰尿酸＞溴＞1,3 - 二溴 - 5,5 - 二甲基乙内酰脲＞N - 溴 - N'- 氯 - 二甲基乙内酰脲＞氯＞三氯异氰尿酸＞1,3 - 二氯 - 5,5 - 二甲基乙内酰脲＞碘＞氯胺T。反应活性差异初步由电子效应、动力学效应和热力学效应来解释。
