| 摘要 |
This invention relates to a process for preparing a product which is predominant in decabromodiphenyl alkane. The process comprises: forming a stirrable reaction mass by adding a solution containing methylene bromide and diphenylalkane to a reaction vessel containing elemental bromine (Br2) and a bromination catalyst; maintaining the reaction mass for a period of time sufficient to achieve perbromination of substantially all of said diphenylalkane; and recovering from the reaction mass the product which is predominant is decabromodiphenyl alkane.
