A method for the production of decabromediphenylalkanen and decabromodiphenylethane.

摘要

BROMINATION PROCESSABSTRACT OF THE DISCLOSUREThis invention relates to a process for preparinga product which is predominant in decabromodiphenylalkane.The process comprises: forming a stirrable reaction massby adding a solution containing methylene bromide anddiphenylalkane to a reaction vessel containing elementalbromine (Br2) and a bromination catalyst; maintainingthe reaction mass for a period of time sufficient toachieve perbromination of substantially all of saiddiphenylalkane; and recovering from the reaction mass theproduct which is predominant in decabromodiphenylalkane.
