Potassium Chlorate Manufacturing

Potassium chlorate is a compound containing potassium, chlorine and oxygen, with the molecular formula KClO3. In pure form, it is a white crystalline substance. It is the most common chlorate in industrial use, and is usually present in well-stocked laboratories. It is used as an oxidizing agent, to prepare oxygen, as a disinfectant, in safety matches, and in explosives and fireworks.

On an industrial scale, potassium chlorate is produced by the electrolysis of a sodium chloride solution to form sodium chlorate, which is reacted with potassium chloride to precipitate potassium chlorate. The resultant sodium chloride is returned to the mother liquor for electrolysis.KClO3 can also be produced on a smaller scale by the thermal disproportionation of a hypochlorite to its respective chlorate and chloride by boiling, then adding KCl. This reaction should be done in a fume hood due to the production of chlorine and chlorine dioxide gas.
