This invention relates to an improvement in a process for preparing a product predominant in decabromodiphenylethane. In the improved process the diphenylethane is reacted with bromine in the presence of bromination catalyst in a reaction vessel by feeding diphenylethane to the reaction vessel below the liquid level of bromine in the reaction vessel. The improvement comprises contacting diphenylethane, bromine, and catalyst at a rate sufficient to obtain a diphenylethane predominant product having enhanced color and particle size.
