Abstract: A process for the preparation of monobromofluoranthene, dibromofluoranthene or their mixtures by bromination of fluoranthene in water or a mixture of water and a water-immiscible inert solvent, if appropriate in the presence of surface-active agents. According to the process, mono- or dibromofluoranthene or mixtures thereof are obtained which are virtually free of by-products. The process products can be used without further purification for the preparation of vat dyes.
