Pharmacology
a-Hexachlorocyclohexane is a brownish-white colored, sand-like powder with a phosgene-like odor that emits toxic fumes of phosgene gas, hydrochloric acid and other chlorinated compounds when heated to decomposition. a-Hexachlorocyclohexane is the alpha-isomer of hexachlorocyclohexane and is used as an insecticide to treat lice and scabies. Inhalation exposure to this substance causes severe irritation of the nose, throat and lungs, causes anemia, and affects the liver, kidneys, nervous system, cardiovascular system and immune system. a-Hexachlorocyclohexane is reasonably anticipated to be a human carcinogen. (NCI05)
How it is made
Chlorination of benzene in actinic light.
Prepared by the chlorination of benzene in the presence of sunlight.
Lindane can be prepared from benzene and chlorine by photochlorination. The resulting benzene hexachloride consists of isomers of which only the gamma-isomer (lindane) is desired, and is obtained by treatment of the reaction mixture with methanol or acetic acid, in which only the alpha and beta isomers dissolve readily.
