Abstract

The flame retarder decabromodiphenylether is prepared by brominating diphenylether in a halogenated hydrocarbon solvent, followed by separation from the reaction medium and purification of the decabromodiphenylether, in which process: (A) the reaction liquid slurry containing decabromodiphenylether is introduced into hot water and then mixture is stream distilled to remove the halogenated hydrocarbon solvent; and (B) the decabromodiphenylether is pulverized to a powder of mean particle diameter not larger than 10 mu . r
