anthracene

anthracene
/an"threuh seen'/, n. Chem.
a colorless, crystalline powder, C14H12, obtained from coal tar and having a violet fluorescence: used chiefly as a source of anthraquinone and alizarin, and in the process of measuring radioactive materials.
[1860-65; ANTHRAC- + -ENE]

      a tricyclic aromatic hydrocarbon found in coal tar and used as a starting material for the manufacture of dyestuffs and in scintillation counters. Crude anthracene crystallizes from a high-boiling coal-tar fraction. It is purified by recrystallization and sublimation. Oxidation yields anthraquinone (q.v.), an intermediate in the production of dyes and pigments. Pure anthracene crystallizes in colourless monoclinic plates, which show a blue fluorescence.
