ABSTRACT:
This invention relates to process for preparing decabromodiphenyl methane, which process comprises: charging a reaction vessel with a first portion of a reaction solvent, a catalytic amount of a halogenation catalyst and from about 10 moles to about 30 moles of bromine per mole of diphenyl methane to be reacted; adding a solution of diphenyl methane and a second portion of the reaction solvent to the charged reaction vessel to form a reaction mass, the reaction mass, as it is being formed, being maintained at a temperature within the range of from about -15.degree. C. to about 15.degree. C.; after the diphenyl methane addition is substantially complete, maintaining the temperature of the reaction mass from about 50.degree. C. to about 80.degree. C.; and recovering from the reaction mass decabromodiphenyl methane.
