| titleOfInvention | Recovery of antimony catalyst residues from bromination reaction mixtures |
| abstract | A method of brominating a styrene polymer in an organic solvent in the presence of an antimony trihalide catalyst such that a reactant containing brominated styrene polymer in the organic phase is formed includes mixing hydrochloric acid or hydrobromic acid, or both, one or more times with the reactant It is improved by extracting the antimony catalyst residue from the reaction mass as an acidic aqueous phase. Preferably, the catalyst residues are recovered from the acidic aqueous phase, and even more preferably the recovered antimony trihalide catalyst residues are regenerated to make up at least a portion of the antimony trihalide catalyst used for the preparation of brominated styrene polymers. . |
