| 摘要 |
Improvements are described in process technology for producing reaction-derived decabromodiphenyl oxide of high purity from (i) diphenyl oxide and/or partially brominated diphenyl oxide and (ii) bromine under specified conditions including substantially concurrently reducing the content of hydrogen bromide present in the reactor sufficiently so that reaction-derived decabromodiphenyl oxide of high purity is formed without requiring procedures such as recrystallization or chromatography to remove lower brominated species, especially nonabromodiphenyl oxide. |
