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:
“[T]he asphaltum contains an exactly requisite amount of sulphides for production of rubber tires. This brown material also contains “ichthyol,” a medicinal preparation used externally, in Webster’s clarifying phrase, “as an alterant and discutient.””
—State of Utah, U.S. public relief program (1935-1943)
“In the production of the necessaries of life Nature is ready enough to assist man.”
—Henry David Thoreau (1817–1862)
“Constant revolutionizing of production ... distinguish the bourgeois epoch from all earlier ones. All fixed, fast-frozen relations, with their train of ancient and venerable prejudices are swept away, all new-formed ones become antiquated before they can ossify. All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind.”
—Karl Marx (1818–1883)
