| 73 | Reduction of aromatic nitro compounds to aromatic azoxy compounds using a pure accicular crystalline benzoquinone as a reduction promoter | US11773571 | 1971-02-22 | US3821190A | 1974-06-28 | BUCKWALTER G |
| In the reduction of reducible aromatic nitrogen compounds by conventional reducing agents, a pure benzoquinone may be employed as a reduction promoter. Impure benzoquinone may be purified by various methods, such as by sublimation and by recrystallization. Substituted benzoquinones, such as halogenated or cyanosubstituted benzoquinones, may be employed. The benzoquinone is employed in an amount ranging from about 0.5 to about 4.0 parts per 100 parts of the reducible aromatic nitrogen compound being treated. The presence of a metallic cyanide in the reaction mixture is advantageous, particularly in the reduction of the aromatic nitrogen from the azoxy to the hydrazo stage.
