Beschreibung

Allgemeine Beschreibung

Potassium chlorate is a shiny colorless solid having monoclinic crystals in the form of platelets. On heating above 400°C, it degrades to give potassium chloride and potassium perchlorate. It has strong oxidizing properties. On exposure to X-rays, oxygen-17 enriched KClO₃ generates O₃^- radical, which was investigated by ESR. On X-ray irradiation potassium chlorate undergoes degradation to generate chloride, chlorite, hypochlorite and occluded oxygen. Significant quantities of dichlorine hexoxide and a trace of chlorine dioxide were also produced.

Anwendung

Potassium chlorate may be used as strong oxidizing agent in the preparation of graphite oxide (GO).
