Great Lakes Chemical Company was founded in Michigan in 1936 to extract bromine from underground salt water brine deposits. It was acquired by McClanahan Oil in 1948 and rechristened Great Lakes Oil and Chemical Company, but by 1960 the company had moved away from oil and gas, instead focusing on the research and production of bromine-based chemicals.
Chemtura, a Philadelphia-based corporation, operates four plants through its subsidiary, Great Lakes Solutions. Three plants are in the vicinity of El Dorado, and all in Union County, Arkansas. In 2007, Chemtura had the capacity to produce 130,000 tonnes of bromine per year. Since 1969, all US bromine has been produced from subsurface brine.
By the end of January 2007 Chemtura completed stock acquisition and ownership of Kaufman Holdings Corporation with an all-cash transaction.

Additionally, TBPH shares many similar structural characteristics (e.g., aromatic rings, bromination) with a class of BFRs called polybrominated diphenyl ethers (PBDEs) which has faced a great deal of attention and numerous restrictions due to their persistence, bioaccumulation, and potential toxicity. These structural similarities have brought ...
