| | 1,4-Benzoquinone dioxime Usage And Synthesis |
| Uses | A rubber accelerator.
| | Chemical Properties | pale yellow to brown crystals or powder | | Uses | p-Benzoquinone dioxime was used in oxidative regeneration of a variety of carbonyl compounds from their oximes using superoxide ion generated in situ by the phase transfer reaction between potassium superoxide and 18-crown-6. | | Definition | ChEBI: Para-Benzoquinone dioxime is a quinone imine. | | General Description | Pale yellow crystals or brown powder. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | 1,4-Benzoquinone dioxime is incompatible with strong oxidizers and strong acids. | | Fire Hazard | Flash point data for 1,4-Benzoquinone dioxime are not available; however, 1,4-Benzoquinone dioxime is probably combustible. | | Flammability and Explosibility | Flammable | | Biochem/physiol Actions | p-Benzoquinone dioxime is sex-specific rat carcinogen inducing tumours of the urinary bladder in female rats and is a direct-acting mutagen in Salmonella typhimurium TA982. | | Safety Profile | Moderately toxic by
ingestion. Questionable carcinogen with
experimental neoplastigenic and tumorigenic
data. Mutation data reported. When heated
to decomposition it emits toxic fumes of
NOx,. | | Synthesis | In recent years, the industrial production of 1,4-benzoquinone dioxime is mainly based on the following method: in the presence of sulfuric acid at a certain concentration at 0C, sodium nitrite nitrosation of phenol dissolved in 30% NaOH solution to produce p-benzoquinone monoxime, and then adding hydroxylamine to oximize the produced p-benzoquinone monoxime to produce the final product 1,4-benzoquinone dioxime. |
