Production
The compound is industrially produced by passing chlorine into the hot milk of lime, subsequently adding the potassium chloride (Liebig process). The electrolysis of KCl water solution is also used sometimes, then the chlorine formed at the anode reacts with KOH in situ. As KClO3 solubility in water decreases significantly when cooling, it can be simply isolated from the reaction mixture.
Can be produced in small amounts by disproportionation a sodium hypochlorite solution followed by metathesis reaction with potassium chloride:
- 3 NaOCl → 2NaCl + NaClO3
- KCl + NaClO3 → NaCl + KClO3
Can also be produced by passing chlorine gas into a hot solution of caustic potash:
- 3Cl2(g) + 6KOH (aq) → KClO3 (aq) + 5KCl (aq) + 3H2O(l)

Famous quotes containing the word production:
“The heart of man ever finds a constant succession of passions, so that the destroying and pulling down of one proves generally to be nothing else but the production and the setting up of another.”
—François, Duc De La Rochefoucauld (1613–1680)
“An art whose limits depend on a moving image, mass audience, and industrial production is bound to differ from an art whose limits depend on language, a limited audience, and individual creation. In short, the filmed novel, in spite of certain resemblances, will inevitably become a different artistic entity from the novel on which it is based.”
—George Bluestone, U.S. educator, critic. “The Limits of the Novel and the Limits of the Film,” Novels Into Film, Johns Hopkins Press (1957)
“The growing of food and the growing of children are both vital to the family’s survival.... Who would dare make the judgment that holding your youngest baby on your lap is less important than weeding a few more yards in the maize field? Yet this is the judgment our society makes constantly. Production of autos, canned soup, advertising copy is important. Housework—cleaning, feeding, and caring—is unimportant.”
—Debbie Taylor (20th century)
