Abstract
Anthraquinone is prepared by oxidizing anthracene dissolved or suspended in acetic acid, by means of oxygen or an oxygen-containing gas in the presence of an oxide of nitrogen with or without another oxygen carrier. Thus, oxygen is passed under pressure into a hot mixture of anthracene and acetic acid containing a little fuming nitric acid; or oxygen containing a small percentage of nitrous gases is introduced into a hot mixture of anthracene and acetic acid containing cobalt nitrate. Similarly, anthracene sulphonic acids can be oxidized to the corresponding quinone compounds.
