High Quality Content by WIKIPEDIA articles! Anthraquinone, also called anthracenedione or dioxoanthracene is an aromatic organic compound with formula C14H8O2, that can be viewed as a diketone derivative of anthracene (with loss of two double bonds in the latter). The term usually refers to one specific isomer, 9,10-anthraquinone or 9,10-dioxoanthracene, whose ketone groups are on the central ring. This compound is an important member of the quinone family. It is a building block of many dyes and is industrially used in bleaching pulp for papermaking. It is a yellow highly crystalline solid, poorly soluble in water but soluble in hot organic solvents. For instance, it is almost completely insoluble in ethanol near room temperature but 2.25 g will dissolve in 100 g of boiling ethanol.
