Abstract: PURPOSE: A method for preparing mixtures of brominated diphenyl ethanes is provided to facilitate reaction control and to consecutively prepare brominated diphenyl ethanes with excellent purity. CONSTITUTION: A method for preparing mixtures of brominated diphenyl ethanes comprises the steps of: injecting a catalyst in a reactor(2) in which a moisture-removed solvent and diphenylethane are mixed; dropping a bromine solution in the reactor and performing the reaction; removing the catalyst from a reaction mass in which the reaction is completed; distilling a reaction mass from which catalyst is removed to obtain the water-dispersed brominated diphenyl ethanes; and filtering and drying the water-dispersed brominated diphenyl ethane mixture.
