Naphthalene is an organic compound with formula C10H8. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass.[1] As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings. It is best known as the main ingredient of traditional mothballs.

Industrial Naphthalene  is white, reddish or yellowish flake crystallization. It has special odour and it is easy to volatilize and sublimate. The highest allowed density in the air is 10ppm,specific gravity is 1.162,melting point is 80.1,boiling point is 217.9,flashing point is78.89, and spontaneous ignition point is 526. Explosion limit: Dust lower limit is 2.5g/m2, steam 0.9~5.9%. It belongs to the second class flammabe solid. It is mainly made up of naphthalene.

3.Application

It is used to produce β-hydroxynaphthalene, water reducer,phthalic anhydride, refined naphthalene , 

dye intermediate and synthetic resin etc..
