Abstract
In the oxidation of anthracene to anthraquinone using nitrogen oxides as catalyst, (1) an acid solvent or suspending-agent, not necessarily anhydrous, is employed, and (2) a nitric-acid fixing agent, e.g. sodium acetate, must be present. When the nitrogen oxides are introduced as a nitrite, the interaction of the acid solvent therewith produces the fixing agent; whereas when the nitrogen oxides are added in the form of fuming nitric acid or in the state of liquid or gas, the fixing agent must be introduced before the reaction commences. According to the examples, anthraquinone is produced by passing oxygen through a mixture of anthracene and glacial acetic acid which contains some sodium nitrite or to which fuming nitric acid and sodium acetate have been added.
