Hazardous Substance Ecological Fact Sheet and Ecotoxicity Profile Hexachloro-1,3-butadiene

Abstract

Hexachloro-1,3-butadiene (hexachlorobutadiene, HCBD) is produced deliberately as a by-product of the manufacture of other chlorinated chemicals. It is used as a solvent for many other organic chemicals, as an intermediate in the manufacture of rubber compounds and lubricants. The largest user of HCBD is the chlorine production industry. HCBD enters the aquatic environment primarily during the disposal of wastes containing HCBD from the chlorinated hydrocarbon industries. HCBD is moderately soluble in water.
