Editing Ammonium perchlorate (section)

==Production==
Ammonium perchlorate (AP) is produced by reaction between [[ammonia]] and [[perchloric acid]].  This process is the main outlet for the industrial production of [[perchloric acid]].  The salt also can be produced by [[salt metathesis reaction]] of ammonium salts with [[sodium perchlorate]].  This process exploits the relatively low solubility of NH<sub>4</sub>ClO<sub>4</sub>, which is about 10% of that for sodium perchlorate.<ref name=Ullmann>Helmut Vogt, Jan Balej, John E.
