1,4-Naphthoquinone Usage And Synthesis

Chemical Properties

yellow to green powder

Chemical Properties

1,4-Naphthoquinone is a yellow to greenishyellow crystalline solid. Pungent odor like benzoquinone.

Uses

antibacterial, antineoplastic

General Description

Yellow needles or brownish green powder with an odor of benzoquinone.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

1,4-Naphthoquinone may react with many acids and bases liberating heat and flammable gases (e.g., H2). The heat may be sufficient to start a fire in the unreacted portion of the ketone. May react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. May react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.

Hazard

Irritant

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition 1,4-Naphthoquinone emits toxic fumes and smoke.

Fire Hazard

Flash point data for 1,4-Naphthoquinone are not available; however, 1,4-Naphthoquinone is probably combustible.

Safety Profile

Poison by ingestion, intravenous, subcutaneous, and intraperitoneal routes. Experimental reproductive effects. Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits acrid smoke and irritating fumes.

Potential Exposure

1,4-Naphthoquinone is used as a polymerization regulator for rubber and polyester resins; in the synthesis of dyes and pharmaceuticals; and as a fungicide and algicide.

Shipping

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Purification Methods

Crystallise the quinone from diethyl ether (charcoal). It distils in steam. It also crystallises from *benzene or aqueous EtOH and sublimes in a vacuum. [Beilstein 7 IV 2422.]

Incompatibilities

Ketones are incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, nitrated amines, azo, diazo, azido compounds, carbamates, organic cyanates. May react with many acids and bases liberating heat and flammable gases (e.g., hydrogen) generating heat may be sufficient to start a fire in the unreacted portion of the ketone. May react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (e.g., hydrogen) and heat. Incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. May react violently with aldehydes.

Waste Disposal

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
