Zusammenfassung:This invention provides a process of preparing reaction-derived decahalodiphenylethane of high purity. The process comprises cofeeding separate feeds of (a) diphenylethane and (b) bromine chloride, bromine chloride and bromine, or bromine chloride and chlorine to a refluxing reaction mixture comprising bromine and at least one Lewis acid bromination catalyst so that high purity decahalodiphenylethane is formed.
