ABSTRACT OF THE DISCLOSURE The invention is concerned with a process for producing condensed bromoacenaphthylene. The process of the invention comprises the steps of brominating and condensating acenaphthene with bromine in a halogen- ated hydrocarbon solvent in the presence of a Lewis acid catalyst; removing the Lewis acid catalyst and then continuing the bromination with bromine with an added radical initiator; and carrying out dehydro- bromination reaction. The condensed bromoacenaphthyl- ene can be purified by bringing it into contact with an adsorbent in an organic solvent. The process according to the invention is simple and impurities can be removed selectively and easily. The condensed bromoacenaphthylene thus purified does not adhere onto a roller when kneaded with a resin on rollers, supresses breeding from a shaped composition, and shaped compo- sitions produced from the condensate have improved mechanical properties.
