consists of two BENZENE rings joined together (with the loss of some carbon and hydrogen--

condensed) to give the formula C
10H
8. It is a white crystalline solid and is obtained from COAL TAR (in the fraction, or part, boiling between 180°C and 200°C) and from PETROLEUM fractions, by demethylation i.e. the removal of the METHYL group from methylnaphthalene. Naphthalene is more reactive than benzene and it is used mostly in the production of plasticizers and resins. Some derivatives of naphthalene are important in the manufacture of dyestuffs.

naphthalin,
bicyclo[4.4.0]deca-1,3,5,7,9-pentene or
antimite and not to be confused with
naphtha, is a crystalline,
aromatic, white, solid
hydrocarbon with formula
C10H8 and the structure of two fused
benzene rings. It is best known as the traditional, primary ingredient of
mothballs. It is volatile, forming an inflammable
vapor, and readily
sublimes at room temperature, producing a characteristic odor that is detectable at concentrations as low as 0.08
ppm by mass.
