Perbromination of phenol and diphenyl ether |
| abstract |
A process for the perbromination of phenol and diphenyl ether by brominating the corresponding compound in bromine as the sole reaction medium using Fe or Al or their compounds as catalysts at an elevated initial reaction temperature of at least about 35 DEG C., and maintaining at least 75% excess of the stoichiometric amount of bromine, substantially enhances reaction productivity without adversely affecting product yield or quality. |
