Abstract

Procédé consistant à effectuer la bromation en milieu solvant organique qui est un hydrocarbure halogéné, de préférence le bromure de méthylène, et en présence d'un catalyseur de bromation qui est un halogénure d'aluminium choisi entre le chlorure d'aluminium et le bromure d'aluminium. Ce procédé permet d'obtenir du décabromodiphényléther de haute pureté.Process consisting in carrying out the bromination in an organic solvent medium which is a halogenated hydrocarbon, preferably methylene bromide, and in the presence of a bromination catalyst which is an aluminum halide chosen between aluminum chloride and bromide d 'aluminum. This process makes it possible to obtain high purity decabromodiphenyl ether.
