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.
