What is Naphthalene?

Naphthalene, the simplest of the fused or condensed ring hydrocarbon compounds composed of two benzene rings sharing two adjacent carbon atoms; chemical formula, C10H8. It is an important hydrocarbon raw material that gives rise to a host of substitution products used in the manufacture of dyestuffs and synthetic resins. Naphthalene is the most abundant single constituent of coal tar, a volatile product from the destructive distillation of coal, and is also formed in modern processes for the high-temperature cracking (breaking up of large molecules) of petroleum. It is commercially produced by crystallization from the intermediate fraction of condensed coal tar and from the heavier fraction of cracked petroleum. The substance crystallizes in lustrous white plates, melting at 80.1° C (176.2° F) and boiling at 218° C (424° F). It is almost insoluble in water. Naphthalene is highly volatile and has a characteristic odour; it has been used as moth repellent.

What is Naphthalene used for?

Naphthalene is used for many things and it is usually mixed with another chemical. It is produced by the burning of fossil fuels, wood, and tobacco. Common uses for naphthalene is listed below.
