Abstract:
A process for purifying crude brominated aromatic compounds such as decabromodiphenyl oxide containing impurities. The crude brominated aromatic compound undergoes a single processing step of grinding in the presence of heated air. The temperature is sufficient to effect substantial removal of impurities and yet remains below the melting point of the brominated aromatic compound.
