Abstract
A chlorine-substituted anthraquinone is treated with a base in presence of an oxidizing-agent, whereby a hydroxy group additional to those replacing the chlorine atoms is introduced. Alizarin, for instance, may be obtained from 2-chloranthraquinone by heating under pressure with caustic soda, sodium nitrate or chlorate, and water, the mixture being stirred.
