Preparation of a brominated fire retarding agent
A fire retarding agent is prepared by reacting a halocyclopentadiene and cyclooctadiene to form Diels-Alder adducts, selectively extracting the mono-adduct from the mixture, brominating the mono-adduct, and separating the brominated product. The extraction solvent is used as the solvent in the bromi...

| Zusammenfassung: | A fire retarding agent is prepared by reacting a halocyclopentadiene and cyclooctadiene to form Diels-Alder adducts, selectively extracting the mono-adduct from the mixture, brominating the mono-adduct, and separating the brominated product. The extraction solvent is used as the solvent in the bromination step and can be recycled for the extraction. |
