|---|---|---|
| Hexachlorobutadiene (HCBD) is a halogenated aliphatic compound, mainly created as a by-product in the manufacture of chlorinated hydrocarbons like tri- and tetrachloroethene and tetrachloromethane. HCBD was – and maybe still is in some countries – used as a fumigant. Some other minor uses of HCBD are reported | van de Plassche and Schwegler., 2003. Hexachlorobutadiene. | Link |
| Hexachlorobutadiene occurs as a by-product during the chlorinolysis of butane derivatives in the production of both carbon tetrachloride and tetrachloroethene. These two commodities are manufactured on such a large scale, that enough HCBD can generally be obtained to meet the industrial demand. Systemic toxicity following exposure via oral, inhalation, and dermal routes. Effects include a range of conditions such as epithelial necrotizing nephritis, fatty liver degeneration, central nervous system depression and cyanosis. Hexachlorobutadiene is classified as a group C Possible Human Carcinogen, the USEPA. | U.S. Environmental Protection Agency accessed 07 October 2020 | Link |
| Hexachlorobutadiene (CAS 87-68-3) is an industrial by-product of tetrachloroethylene, trichloroethylene, and perchloroethylene production. It is used as a solvent for elastomers, heat transfer liquids, transformer fluids, and hydraulic fluids and may still be used in certain countries as a fumigant in vineyards. Hexachlorobutadiene can elicit toxicity via oral, dermal, and inhalation exposure routes and is a nephrotoxicant and carcinogen. | Janz. 2014. Hexachlorobutadiene | Link |
| Hexachlorobutadiene, Cl2C=CClCCl=CCl2, is a colorless liquid at room temperature that has an odor similar to that of turpentine. it is a chlorinated aliphatic diene with niche applications but is most unremarkably used as a solvent for other chlorine-containing compounds. | Marshall et al., 2016.
