Description

Acenaphthene is a tricyclic aromatic hydrocarbon, crystalline solid at ambient tempera- ture. Acenaphthene does not dissolve in water, but is soluble in many organic solvents. Acenaphthene occurs in coal tar produced during high temperature carbonization or cok- ing 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

Acenaphthene is a polycyclic aromatic hydrocarbon (PAH) consisting of naphthalene with an ethylene bridge connecting positions 1 and 8. It is a colourless solid. Coal tar consists of about 0.3% of this compound.

Acenaphthene Use and Manufacturing

Methods of Manufacturing

In high temperature tar, it contains about 1.2%-1.8% of acenaphthene. The washing oil separated by coal tar distillation is divided into narrow fractions by rectification method, and industrial acenaphthene is prepared from 270-280°C fractions.

Uses

Dye intermediate; manufacture of plastics; insecticide; fungicide.
