| | 4-Hydroxydiphenylamine Usage And Synthesis |
| Uses | 4-Hydroxydiphenylamine is used as a reactant in the preparation of iron methylisopropylglyoxime dimethylpyridine/dimethylaminopyridine/phenylaminophenol/imidazolidone complexes. | | Definition | Gray solid leaflets. Insoluble in water; soluble
in alcohol, ether, acetone, chloroform, alkali, and
benzene. | | Hazard | Irritant. | | Safety Profile | Poison by intravenous route.Moderately toxic by ingestion. A severe eye irritant. Seealso AROMATIC AMINES. When heated todecomposition it emits toxic fumes of NOx. | | Purification Methods | Crystallise the amine from chlorobenzene/pet ether, pentane (m 72o) or *C6H6/pet ether (m 70o).
