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,.
