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.
