METHOD FOR PRODUCTION OF BROMINE Russian patent published in 1998 - IPC

FIELD: technology for production of bromine of bromine-containing solutions; chemical and other branches of industry. SUBSTANCE: method involves adsorption of bromine of bromine-containing solution with the help of ionite and desorption of bromine of ionite. Said desorption is carried out with the help of vapor, the process is followed by production of liquid bromine which takes place by condensation of vapor-bromine mixture at 10.000-25.000 Pa. It is advisable to treat ionite after adsorption with bromine water, said bromine water is produced after condensation of vapor-bromine mixture and after separation of bromine. No additional expense of chemical reagents for desorption of bromine is needed. EFFECT: decreased expense of vapor by production of bromine. 3 cl, 1 tbl
