Industrial uses: Chemical reaction regulator, Oxidizing agent.

Consumer uses: Oxidizing agent.

Functional uses

  • Dye
  • Intermediate
  • Pigment
  • Surface modifier

Pharmacology

Anthraquinone is a polycyclic aromatic hydrocarbon derived from anthracene or phthalic anhydride. Anthraquinone is used in the manufacture of dyes, in the textile and pulp industries, and as a bird repellant.

How it is made

Through the oxidation of naphthalene to naphthaquinone, which is condensed with butadiene to yield tetrahydroanthraquinone, this is dehydrogenated to produce anthraquinone.

Industrial preperation from phthalic anhydride and benzene: From anthracene with vanadium pentoxide, sodium chlorate, glacial acetic, and sulfuric acids.

Anthracene + nitric acid, concentrated (nitric acid oxidation process), o-Benzoylbenzoic acid (acid-catalyzed condensation)
