Description and Uses
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.
Acenaphthene occurs in petroleum bottoms and is used as a dye intermediate, insecticide, and fungicide and in manufacturing plastics.
