Description

General description
Perchloric acid (HClO₄) is a strong mineral acid. It has powerful oxidizing and dehydrating properties when it is hot and concentrated. It is commercially available in a concentration of 70% (by weight) in water. Aqueous solution of HClO₄ is regarded as a super acid (stronger than sulfuric and nitric acids), but it is not necessarily a powerful oxidizer.
Application
Perchloric acid can be used:
In the synthesis of graphite oxide via electrochemical oxidation of natural graphite.
As a reaction medium in oxidations reactions.
As a dopant in the preparation of perchloric acid-functionalized polyaniline (HClO₄/PANI) catalyst for the synthesis of 2-substituted benzothiazoles by condensation reaction between o-aminothiophenol with aldehydes.

It can also be used in the following:
Silica-supported perchloric acid (HClO₄-SiO₂) is used as a catalyst to synthesize amidoalkyl naphthols by the condensation reaction of 2-naphthol, aromatic aldehydes, and acetonitrile.
HClO₄-SiO₂ is used in the Friedlander quinoline synthesis by the condensation reaction of 2-aminoaryl ketones and carbonyl compounds.
Alumina-supported perchloric acid (Al₂O₃-HClO₄) is used as a catalyst in the synthesis of α-(α-amidobenzyl)-β-naphthols.
