[f. Gr. ἀνθρακ- (-αξ) coal + -ene.]
a. A complex hydrocarbon, called in systematic nomenclature Para-naphthalin, obtained from coal-tar; discovered in 1832 in the heavy semifluid portion of the tar which comes over towards the close of the distillation. It belongs to the aromatic or Benzol group, has composition C14H10 = C6H2(C4H4)2 = (C6H4)2C2H2, and passes under influence of light into the isomeric paranthracene.
