I have a convoluted connection to the winter holidays. What molecule am I? Potassium chlorate hazard information. Potassium chlorate fast facts. Potassium chlorate is used in the oxygen-supply systems of aircraft, and has been responsible for at least one plane crash.
A fire on the space station MIR was also traced to this substance. The decomposition of potassium chlorate was also used to provide the oxygen supply for limelights. Potassium chlorate is used also as a pesticide. In Finland it is sold under trade name Fegabit. Potassium chlorate should be handled with care. It reacts vigorously, and in some cases spontaneously ignites or explodes, when mixed with many combustible materials.
Sulfur should be avoided in compositions of gunpowder containing potassium chlorate, as these mixtures are prone to spontaneous deflagration. 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. KClO 3 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. Potassium chlorate's insolubility means it is easy to separate from soluble contaminants, but relatively difficult to separate from insoluble ones, for example electrode or cell matter.
