ACENAPHTHYLENE Chemical Properties,Uses,Production


Acenaphthylene is a PAH with three aromatic rings. It is an intermediate chemical for the manufacture of dyes, soaps, pigments, pharmaceuticals, insecticides, fungicides, herbicides, plant growth hormones, naphthalic acids, naphthalic anhydride (pigments), and acenaphthylene (resins) and is used to manufacture plastics. The largest emissions of PAHs result from incomplete combustion of organic materials during industrial processes and other human activities. These include (1) processing of coal, crude oil, and natural gas, including coking, coal conversion, and petroleum refining; (2) production of carbon blacks, creosote, coal tar, and bitumen; (3) aluminium, iron, and steel production in plants and foundries; (4) heating in power plants and residences and cooking; (5) combustion of refuse; (6) motor vehicle traffic; and (7) environmental tobacco smoke.

Chemical Properties

Acenaphthylene is a polycyclic aromatic hydrocarbon (PAH) with three aromatic rings. It is used to manufacture plastics. Intermediate for dyes, soaps, pigments, pharmaceuticals, insec- ticide, fungicide, herbicide, and plant growth hormones. Intermediate for naphthalic acids, naphthalic anhydride (intermediate for pigments), and acenaphthylene (intermediate for res- ins). The largest emissions of PAH result from incomplete combustion of organic materials during industrial processes and other human activities. These include (a) processing of coal, crude oil, and natural gas, including coal; (b) coking, coal conversion, petroleum refi ning, and production of carbon blacks, creosote, coal-tar, and bitumen; (c) aluminium, iron, and steel production in plants and foundries; (d) heating in power plants and residences and cooking; (e) combustion of refuse; (f) motor vehicle traffi c; and (g) environmental tobacco smoke.

Chemical Properties

Acenaphthylene is a flaky yellow crystalline powder or solid.


Polycyclic aromatic hydrocarbons as carcinogenic


ChEBI: A ortho- and peri-fused tricyclic hydrocarbon that occurs in coal tar.

General Description

Colorless crystalline solid. Insoluble in water. Used in dye synthesis, insecticides, fungicides, and in the manufacture of plastics.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as ACENAPHTHYLENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.

Health Hazard

Acenapht hylene is i rritat i ng to t he sk i n a nd mucous membra nes of rabbits. Subc h ron ic oral doses of acenaphthylene caused adverse effects to the kidneys, liver, blood, reproductive system, and lungs of experimental animals. Prolonged period of inhalation at low doses caused pulmonary effects like bronchitis, pneumonia, and desquamation of the bronchial and alveolar epithelium in rats.

Potential Exposure

PAHs are compounds containing multiple benzene rings and are also called polynuclear aromatic hydrocarbons. Acenaphthylene is an aromatic hydrocarbon used in coal tar processing, as a dye intermediate; making insecticides, fungicides, plastics.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. If this chemical contacts the skin, remove contaminated clothing, and wash with soap immediately. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make anunconscious person vomit. If this chemical has been inhaled, remove from exposure and transfer promptly to a medical facility.


UN3143 Dye intermediates, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous material, Hazard, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

Purification Methods

Dissolve acenaphthylene in warm redistilled MeOH, filter through a sintered glass funnel and cool to -78o to precipitate the material as yellow plates [Dainton et al. Trans Faraday Soc 56 1784 1960]. Alternatively it can be sublimed in vacuo. [Beilstein 5 H 625, 5 IV 2138.]


Keep away from ozone and strong oxidizing agents. 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

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. Product residues and sorbent media may be packaged in epoxy-lined drums, then destroyed by incineration, permanganate oxidation or microwave plasma treatment. The United States Environmental Protection Agency has investigated chemical precipitation for wastewater treatment
