C14H8O2

C14H8O2 is the chemical formula for anthraquinone, also known as 9,10-anthracenedione. It is an aromatic diketone derived from the anthracene structure, with two carbonyl groups at the 9 and 10 positions. The molecule consists of three fused benzene rings and has the formula C14H8O2. It appears as a yellow to pale orange crystalline solid, with limited water solubility and greater solubility in many organic solvents. Its melting point is around 284–286°C.

Production and occurrence: Anthraquinone is produced industrially by the oxidation of anthracene with oxygen, typically in the gas phase over catalysts such as vanadium oxide on a solid support. It can also be obtained from coal tar sources. The compound serves as a key intermediate in the manufacture of a broad range of dyes and pigments.

Applications: The primary use of anthraquinone is as a starting material for numerous anthraquinone dyes and pigments. It also features in the industrial production of hydrogen peroxide through the anthraquinone process, in which anthraquinone is cyclically reduced and oxidized to generate hydrogen peroxide.

Safety: Anthraquinone is generally handled as a chemical with low to moderate acute toxicity and can act as an irritant to skin, eyes, and the respiratory system. Proper handling, adequate ventilation, and adherence to disposal regulations are recommended to minimize exposure and environmental impact.
