Naphthalene (not to be confused with
naphtha) (also known as naphthalin, naphthaline, moth ball, tar camphor, white tar, or albocarbon), is a crystalline,
aromatic, white, solid
hydrocarbon, best known as the primary ingredient of
mothballs. Naphthalene is volatile, forming a flammable
vapor. Its
molecules consist of two fused
benzene rings. It is manufactured from
coal tar, and converted to
phthalic anhydride for the manufacture of
plastics,
dyes and
solvents. It is also used as an
antiseptic and
insecticide, especially in mothballs.
p-Dichlorobenzene is now often used instead of naphthalene as a mothball substitute. Naphthalene easily
sublimates at room temperature.
