Abstract: The invention relates to a process for preparing bromine-containing polymer, comprising a Friedel-Crafts alkylation reaction of tetrabromoxylylene dihalide, or tetrabromoxylylene dihalide in combination with pentabromobenzyl halide, with a reactant having one or more six-membered aromatic rings, wherein the reaction takes place in a solvent in the presence of a Friedel-Crafts catalyst, and isolating from the reaction mixture the bromine-containing polymer. The so-formed polymers and their use as flame retardants form additional aspects of the invention.

Abstract: The invention relates to a process for recovering bromide from a halide-containing aqueous stream, comprising the steps of: providing a feed of halide-containing aqueous stream; contacting an anion-exchange resin with said feed, to form halide-loaded resin; treating said halide-loaded resin with a regenerant and subsequently with a rinse to produce, in succession, a chloride-rich solution, a mixed chloride/bromide solution, a bromide-rich solution and an essentially halide-free solution; directing said mixed chloride/bromide solution to said feed; processing said bromide-rich solution to recover one or more bromide products; and utilizing said essentially halide-free solution for regenerant dilution and/or rinsing of said resin. An apparatus for carrying out the process is also disclosed.

Abstract: A solvent extraction process for recovering bromide from a sulfate-containing aqueous stream, the process comprises an extraction step wherein said aqueous stream is mixed with an extraction medium comprising a tertiary amine extractant dissolved in one or more water-immiscible organic solvents, wherein said mixing is carried out in a strongly acidic environment, thereby forming bromide-containing extract and a raffinate with a reduced bromide level, wherein the bromide-containing extract is optionally treated to further minimize the presence of sulfate and is subsequently combined with an aqueous calcium source to form calcium bromide.

Abstract: The invention provides a process for preparing bromine-containing polymers, comprising a Friedel-Crafts alkylation reaction of pentabromobenzyl halide with a polymer reactant which contains one or more six-membered aromatic ring(s) in its repeat unit, in the presence of at least one Friedel-Crafts catalyst. The so-formed bromine-containing polymers, having pendent —CH2C6Br5 groups attached to at least a portion of the six-membered aromatic rings of the polymer, with a carbon ring atom of said six-membered aromatic ring being bonded to the aliphatic carbon of said —CH2C6Br5 pendent group, are also provided. These bromine-containing polymers are useful as flame retarding agents.
