    • A process for producing reaction-derived decabromodiphenylalkane product, especially decabromodiphenylethane product, of high assay is described. Diphenylalkane, preferably diphenylethane, is brominated by introducing the selected diphenylalkane in the form of a mist or spray into a reaction zone containing a reaction mixture having a liquid phase comprised of excess bromine and Lewis acid bromination catalyst, so that mist or spray of diphenylalkane descends onto and contacts the liquid phase of the reaction mixture and bromination of the diphenylalkane occurs to produce reaction-derived decabromodiphenylalkane product of high assay. Preferably, the reaction mixture is maintained under reflux and optionally is also stirred.
