Abstract:
A new process for recovery of bromine from the solut ion containing bromine ion is studied. In the presence of acid, through ox idat ing with chlorine gas and then ex tract ing w ith CCl4, obtain the bromine CCl4 solution w hich can be used for organic brominating react ions w ithout further purif icat ion, and the CCl4 can be obtained through dist illat ion after the react ion. T he percentage of bromine recovery is 97 %. The bromine CCl4 solut ion can also be used for preparat ion of pure bromine by ext racting w ith NaOH solut ion and then adding acid to it for neutralizing. T he recovery percentag e is 95 % . Compared w ith the other processes, the new process has the advantages of low er cost, simple equipment and lower pollution.
