anthrachinone

Anthrachinone is not a widely used term in modern chemical literature. It most often refers to anthraquinone (9,10-anthraquinone) or to derivatives based on the same structural motif, an anthracene ring system bearing two ketone groups. In many sources, the spelling anthrachinone may be encountered as a variant or misspelling of anthraquinone.

Structure and basic properties: The parent compound is an aromatic diketone with two carbonyl groups at the 9 and 10 positions of the anthracene framework. Its formula is C14H8O2. It appears as a pale yellow to colorless crystalline solid that is insoluble in water and soluble in many organic solvents. It is relatively chemically stable and can be reduced to yield anthracene.

Occurrence and production: Anthraquinone can occur in trace amounts in some natural sources. Industrial production is mainly by oxidation of anthracene to anthraquinone using air and catalysts. The process yields the parent compound on a large scale and provides a key building block for further chemical synthesis.

Uses: The principal use of anthraquinone and many of its derivatives is as an intermediate in the manufacture of dyes and pigments, particularly vat dyes. It serves as a versatile core for various anthraquinone-based dyes and as a precursor in the synthesis of related organic compounds used in industry.

Safety: Anthraquinone and its derivatives are handled as industrial chemicals with standard safety precautions. Exposure may irritate the skin, eyes, or respiratory tract; appropriate protective equipment and ventilation are advised.
