Description
Hexachlorobenzene is a white crystalline solid. HEXACHLOROBENZENE does not occur naturally.
It is formed as a by-product during the manufacture of chemicals used as solvents
(substances used to dissolve other substances), other chlorine-containing compounds,
and pesticides. Small amounts of hexachlorobenzene can also be produced during combustion
processes such as burning of city wastes. It may also be produced as a by-product
in waste streams of chlor-alkali and wood-preserving plants. Hexachlorobenzene
was widely used as a pesticide until 1965. It was also used to make fireworks, ammunition,
and synthetic rubber.

Uses
Seed fungicide In organic syntheses. Formerly as agricultural fungicide. Hexachlorobenzene is used as a fungicideand as an intermediate in organic synthesis. No commercial uses of hexachlorobenzene as an end product in the United States were identified (ATSDR 2002). Previously, it was used as a seed-treatment fungicide for onions, sorghum, wheat, and other grains (IARC 1979). All registered pesticide uses in the United States were voluntarily cancelled in 1984 (ATSDR 2002). Hexachlorobenzene was also used as a chemical intermediate in dye manufacturing, in the synthesis of other organic chemicals, and in the production of pyrotechnic compositions for the military. It was used as a raw material for synthetic rubber, as a plasticizer for polyvinyl chloride, as a porosity controller in the manufacture of electrodes, and as a wood preservative (IARC 1979, ATSDR 2002).
