Description and Uses
Acenaphthylene is a polycyclic aromatic hydrocarbon (PAH) consisting of three fused aromatic rings. It is used in the production of plastics and serves as an intermediate in the manufacture of dyes, soaps, pigments, pharmaceuticals, insecticides, fungicides, herbicides, and plant growth regulators. It is also a precursor to naphthalic acids, naphthalic anhydride (which is used in pigment production), and can be utilized in the synthesis of resins.
The largest emissions of PAHs originate from the incomplete combustion of organic matter during industrial processes and other human activities. Major sources include:
(a) the processing of coal, crude oil, and natural gas;
(b) coking, coal conversion, petroleum refining, and the production of carbon black, creosote, coal tar, and bitumen;
(c) aluminum, iron, and steel production in plants and foundries;
(d) heating in power plants and households, as well as cooking;
(e) combustion of waste;
(f) motor vehicle emissions;
(g) environmental tobacco smoke.
