    Description / Table of Contents: Subreactions in the Chloramine Preparation.In the preparation of chloramine from solutions of ammonia and sodium hypochlorite there is considerable overchlorination, resulting in the formation and subsequent decomposition of dichloramine. Nitrogen, chloride ion, and hypochlorite ion are formed in the decomposition of dichloramine; in the presence of certain organic compounds the products of chlorination via radicals are observed. Chloramine is obtained in over 90% yield by neutralizing the alkali formed in the reaction of ammonia with hypochlorite. Etheral solutions of dichloramine are prepared from chloramine solutions by treatment with phosphate buffer.
    Notes: Bei der Herstellug von Chloraminlösungen aus Ammoniak und Natriumhypochlorit läuft als Nebenreaktion eine Überchlorierung zu Dichloramin ab. Dichloramin zersetzt sich in alkalischer Lösung schnell zu Stickstoff, Chlorid und Hypochlorit; bei Gegenwart organischer Substanzen werden radikalische Chlorierungen beobachtet. Chloraminlösungen lassen sich in über 90proz. Ausbeute herstellen, wenn man das sich bei der Reaktion bildende Alkali abfängt. Lösungen von Dichloramin werden durch Disproportionierung von Chloramin fast quantitativ erhalten.
