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,.
