9,10-Dihydroxyanthracene is the hydroquinone form of 9,10-anthraquinone (AQ) and is formed when AQ is used as a redox catalyst in various industrial processes. It is easily dissolved in alkaline solutions and is often called soluble anthraquinone (SAQ).

In the so-called anthraquinone process, hydrogen peroxide is manufactured as one of the product in the oxygen oxidation of a substituted 9,10-Dihydroxyanthracene to its corresponding anthraquinone, such as 2-Ethylanthraquinone.

Manufacture

Soluble anthraquinone is made by reducing a water dispersion of AQ with carboxylic acids in presence of alkali.
