p-Benzoquinone Usage And Synthesis

Chemical Properties	gold powder
General Description	A yellowish-colored crystalline solid with a pungent, irritating odor. Poisonous by ingestion or inhalation of vapors. May severely damage skin, eyes and mucous membranes. Used to make dyes and as a photographic chemical.
Air & Water Reactions	Soluble in water and denser than water. If moist 1,4-Benzoquinone may decompose spontaneously above 140°F. This has occurred in drums, causing over-pressurization.
Reactivity Profile	1,4-Benzoquinone acts as an oxidizing agent .
Health Hazard	Poisonous; may be fatal if inhaled, swallowed or absorbed through the skin. Contact with solid, vapor or solution can cause severe local damage to the skin and mucous membranes. Symptoms include discoloration, severe irritation, erythema, swelling, papules and vesicles. Necrosis may result from long exposure. The eyes may experience irritation, conjunctivitis, photophobia, lacrymation and burning sensations. The cornea may suffer ulceration and scarring. Chronic eye exposure causes gradual brownish discoloration of the conjunctiva and cornea, small corneal opacities and damage in corneal structure which cause loss of visual acuity.
