IUPAC Name: 1,1,2,3,4,4-hexachlorobuta-1,3-diene
Source: Used in the manufacturing processes of rubber, lubricants, and chlorinated compounds.
Summary: Hexachlorobutadiene (HCBD) is used in the production of rubber compounds, lubricants, and as a solvent for chlorinated compounds. It also has uses as a fungicide. It may be formed as a byproduct of the chemical manufacturing process for carbon tetrachloride, trichloroethylene, and tetrachloroethylene. It is a colorless liquid at room temperature with a density of 1.556 g/mL at 25 C. It is soluble in water up to 3.20 mg/L at 25 C. Upon decomposition it produces chloride and chlorine gas. It is classified by the EPA as a Hazardous Air Pollutant (HAPs). The compound will exist in the vapor-phase in the atmosphere and will undergo photodegradation with a half-life of 534 days. It has low mobility within soil and will adsorb to suspended solids in water. Bioaccumulation within aquatic organisms is high with a biological half-life of 117.49 days.
