Additional recommended knowledge
Anthraquinones naturally occur in some plants (eg. aloe, senna, rhubarb, and Cascara buckthorn), fungi, lichens, and insects, where they serve as a basic skeleton for their pigments. Natural anthraquinone derivatives tend to have laxative effects.
There are several ways to obtain anthraquinone:
In a classic organic reaction called the Bally-Scholl synthesis (1905), anthraquinone condenses with glycerol forming benzanthrone. In this reaction the quinone is first reduced with copper metal in sulfuric acid (converting one ketone group into a methylene group) after which the glycerol is added.
Anthraquinone is used in production of dyes, such as alizarin. Many natural pigments are derivatives of anthraquinone. Anthraquinone is also used as a catalyst in production of wood pulp in pulp and paper industry. Another use is as a bird repellant on seeds.
A derivative of anthraquinone (2-ethylanthraquinone) is used to produce hydrogen peroxide commercially.
