Dibenz[a,h]anthracene Chemical Properties,Uses,Production

Description

1, 2:5, 6-DIBENZANTHRACENE is a crystalline aromatic hydrocarbon. It is a component of coal tars, shale oils, and soots (IARC, 1985) and has been detected in gasoline engine exhaust, coke oven emissions, cigarette smoke, charcoal broiled meats, vegetation near heavily traveled roads, and surface water and soils near hazardous waste sites. It is a kind of carcinogenic compound, and thus being mainly used for the research purpose. For example, in biological research, it is a mutagen used to induce tumorigenesis.

Chemical Properties

Dibenz[a,h]anthracene is a white crystalline solid. It is insoluble in water, slightly soluble in alcohol, and soluble in ether. This compound is incompatible with strong oxidizers.

Physical properties

Colorless to pale yellow, monoclinic or orthorhombic crystals which with a faint, pleasant odor.

Uses

Dibenz[a,h]anthracene is a polycyclic aromatic hydrocarbon (PAH) and a known carcinogen. Dibenz[a,h]anthracene has produced positive results in bacterial DNA damage and mutagenicity assays and in mammalian cell DNA damage, mutagenicity and cell transformation assays.

Production Methods

There is no commercial production or known use of this compound. It has been isolated from the coal tar pitch and is found in coke over effluents. It has been detected in urban atmospheres and occurs in tobacco smoke. Dibenz [a,h]anthracene is present as a minor component of the total PAH content in the environment. Human exposure occurs through smoking, inhaling of polluted air, and by ingesting food and water containing combustion products.

General Description

White crystals or pale yellow solid. Sublimes.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

1,2:5,6-DIBENZANTHRACENE is incompatible with strong oxidizing agents. Is oxidized by chromic acid and by osmium tetraoxide .

Health Hazard

The toxicity of dibenz[a,h]anthracene is onthe same order as that of benz[a]anthracene.A lethal dose in mice by intravenous routeis 10 mg/kg. There is no report on its oraltoxicity. It is a mutagen. Its carcinogenicityin animals is well established, causing cancersin the lungs, liver, kidney, and skin.

Fire Hazard

Flash point data for 1,2:5,6-DIBENZANTHRACENE are not available; however, 1,2:5,6-DIBENZANTHRACENE is probably combustible.

Safety Profile

Confirmed carcinogen with experimental carcinogenic, tumorigenic, and neoplastigenic data. Poison by intravenous route. Human mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes.

Potential Exposure

Dibenz(a,h)anthracene is a chemical substance formed during the incomplete burning of fossil fuel, garbage, or any organic matter and is found in smoke in general; it condenses on dust particles and is distributed into water and soil and on crops. DB(a,h)A is a PAH and is also a component of coal tar pitch, which is used in industry as a binder for electrodes, and creosote is used to preserve wood. PAHs are also found in limited amounts in bituminous materials and asphalt used in industry and for paving.

Carcinogenicity

Based on no human data and sufficient data from animal assays, IRIS classifies dibenz [a,h]anthracene as a B2 carcinogen, a probable human carcinogen, and the IARC classifies dibenz[a,h]anthracene as a 2A carcinogen. Dibenz[a,h]anthracene produced carcinomas in mice following oral or dermal administration and injection site tumors in several species following s.c. or i.m. injection. It is also a tumor initiator.

Shipping

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

Purification Methods

The yellow-green colour (due to other pentacyclic impurities) is removed from it by crystallising from *benzene or by selective oxidation with lead tetraacetate in acetic acid [Moriconi et al. J Am Chem Soc 82 3441 1960]. [Beilstein 5 IV 2722.]

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explo- sions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides.

Waste Disposal

See the entry on Coal Tar Pitch Volatiles. 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.
