Hexachlorobutadiene

Hexachlorobutadiene (CAS 87-68-3), commonly referred to as HCBD, is a dense chlorinated solvent historically used in industrial cleaning and chemical processing operations.

It functions primarily as a solvent for other chlorine-containing compounds and has been applied in high-temperature or chemically aggressive environments where conventional solvents fail.

In oil and gas processing, HCBD has been used to recover chlorine-containing byproducts generated during the production of chlorinated solvents such as trichloroethylene and tetrachloroethylene.

It serves as a fumigant and grain protectant in legacy agricultural applications, though regulatory restrictions have significantly curtailed this use in modern industrial settings.

In lubricant and metalworking contexts, its chemical stability under thermal stress made it a candidate for specialized hydraulic fluids and heat transfer media for various systems.

It has also been used as a wash liquid in gas scrubbing systems to remove impurities from chlorine-based process streams, ensuring higher purity levels for downstream manufacturing.

Hexachlorobutadiene is supplied as a liquid at ambient conditions. Technical-grade material is the standard commercial form, typically offered in drums or bulk quantities for procurement.

Buyers should verify current import, export, and handling regulations, as HCBD is subject to restrictions under international chemical conventions in multiple global jurisdictions.
