Acenaphthene Chemical Properties,Uses,Production


Acenaphthene is a tricyclic aromatic hydrocarbon and crystalline solid at ambient temperature. Acenaphthene does not dissolve in water but is soluble in many organic solvents. Acenaphthene is a component of crude oil and a product of combustion. Acenaphthene occurs in coal tar produced during the high-temperature carbonisation or coking of coal. It is used as a dye intermediate in the manufacture of some plastics and as an insecticide and fungicide. Acenaphthene is a component of crude oil and a product of combustion which may be produced and released to the environment during natural fires. Emissions from petroleum refining, coal tar distillation, coal combustion, and diesel-fuelled engines are major contributors of acenaphthene to the environment. Acenaphthene is an environmental pollutant and has been detected in cigarette smoke, automobile exhausts, and urban air; in effluents from petrochemical, pesticide, and wood preservative industries; and in soils, groundwater, and surface waters at hazardous waste sites. This compound is one among a number of polycyclic aromatic hydrocarbons (PAHs) on U.S. EPA’s (Environmental Protection Agency) priority pollutant list.

Chemical Properties

white or pale yellow crystalline powder


Polycyclic aromatic hydrocarbons as carcinogenic


ChEBI: A polycyclic aromatic hydrocarbon derived from naphthalene by the addition of an ethylene bridge connecting C-1 and C-8.


Dye intermediate; manufacture of plastics; insecticide; fungicide.

General Description

White needles. Melting point 93.6°C. Soluble in hot alcohol. Denser than water and insoluble in water. Hence sinks in water. May irritate skin and mucous membranes. Emits acrid smoke and irritating fumes when heated to decomposition. Derived from coal tar and used to make dyes, pharmaceuticals, insecticides, fungicides, and plastics.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Acenaphthene is incompatible with strong oxidizing agents. Incompatible with ozone and chlorinating agents. Forms crystalline complexes with desoxycholic acid .

Fire Hazard

Flash point data for Acenaphthene are not available. Acenaphthene is probably combustible.

Purification Methods

It has also been purified by chromatography from CCl4 on alumina with *benzene as eluent [McLaughlin & Zainal J Chem Soc 2485 1960]. [Beilstein 5 IV 1834.]
