anthracene

(ăn`thrəsēn), C14H10, solid organic compound derived from coal tar. It melts at 218&degC; and boils at 354&degC;. When pure it is colorless and has a violet fluorescence; it darkens when exposed to sunlight. Anthracene is insoluble in water but is quite soluble in carbon disulfide and somewhat soluble in ethanol, methanol, benzene, chloroform, and other organic solvents. It is readily oxidized to form anthraquinone, the parent compound of the alizarinalizarin
, or 1,2-dihydroxyanthraquinone, mordant vegetable dye obtained originally from the root of the madder plant (Rubia tinctorum), in which it occurs as a glucoside. The term also includes a group of synthetic dyestuffs prepared from coal-tar derivatives.
