Abstract: Polybrominated bisaryl compounds containing bromomethyl or bromomethylene groups are provided, as well as flameproof polymeric formulations comprising the compounds. The novel compounds exhibit a good thermal stability, and are particularly suitable for flame-retarding polystyrene thermoplastic foams. A process for making the polybrominated bisaryl compounds is also provided.

Abstract: A continuous process of preparing bromopicrin is disclosed. The process is effected by transferring a continuous flow of a first mixture and a continuous flow of a second mixture into a first reactor, the first mixture containing nitromethane and bromine and the second mixture containing an aqueous solution of an alkaline substance, to thereby obtain a reaction mixture which comprises bromopicrin in said first reactor; and collecting the bromopicrin from the reaction mixture. Highly pure bromopicrin obtained by this process is also disclosed.
