Abstract

Procédé consistant à effectuer une bromation complémentaire dans un solvant organique qui est de préférence le bromure de méthylène et en présence d'un catalyseur de bromation qui est un halogénure d'aluminium choisi entre le bromure d'aluminium. Ce procédé permet la transformation des produits sous-bromés en produits perbromés.Process consisting in carrying out complementary bromination in an organic solvent which is preferably methylene bromide and in the presence of a bromination catalyst which is an aluminum halide chosen from aluminum bromide. This process allows the transformation of subbrominated products into perbrominated products.
