Potassium perchlorate in crystal form. Potassium perchlorate is prepared industrially by treating an aqueous solution of sodium perchlorate with potassium chloride.This single precipitation reaction exploits the low solubility of KClO 4, which is about 1/100 as much as the solubility of NaClO 4 (209.6 g/100 mL at 25 °C).
Hodgdon also makes "Triple Seven", a sulfur-free black powder substitute containing potassium perchlorate and 3-Nitrobenzoic acid, and "Black Mag3". [10] These are both more energetic by mass than black powder and can produce higher velocities and pressures.

Alternatively, potassium perchlorate reacts with excess fluorosulfuric acid to give potassium bisulfate and perchloryl fluoride: [8] KClO 4 + HFSO 3 → KHSO 4 + FClO 3. ClO 3 F reacts with alcohols to produce alkyl perchlorates, which are extremely shock-sensitive explosives. [9] In the presence of a Lewis acid, it can be used for introducing ...
Perchlorate concentration was the highest in Chilean nitrate, ranging from 3.3 to 3.98%. [51] Perchlorate in the solid fertilizer ranged from 0.7 to 2.0 mg g −1, variation of less than a factor of 3 and it is estimated that sodium nitrate fertilizers derived from Chilean caliche contain approximately 0.5–2 mg g −1 of perchlorate anion.
