C 14 H 8 O 2 (208.22). In the broad sense, it refers to quinone derived from anthracene, and there are three isomers, 1,2-, 1,4-, and 9,10-anthraquinone, but it usually refers to 9,10-anthracenedione. It is produced by oxidizing anthracene, or by dehydrating and cyclizing o -benzoylbenzoic acid obtained by Friedel-Crafts condensation of phthalic anhydride and benzene. Pale yellow crystals. Melting point 286 °C, boiling point 382 °C. Sublimable. Dissolves in benzene, toluene, etc. when heated. When reduced, it produces anthrahydroquinone, anthrone, or anthracene, depending on the type of reducing agent. Anthraquinone is the parent compound of so-called anthraquinone dyes, and acid dyes and vat dyes are synthesized through various derivatives such as quinizarin, aminoanthraquinone, and benzoanthrone.
