METHOD TO MANUFACTURE NON-HAZARDOUS BROMINATING AGENT Russian patent published in 2008 - IPC C01B11/20 C01B9/04 

FIELD: chemistry.

SUBSTANCE: method to manufacture non-hazardous brominating agent by oxidizing a source of bromide ions to bromate ions implies dissolving an alkali in deionised water; dispergating bromide ion source with bromide to bromate ratio from 4:1 to 5:1 in 0.5-2.0 parts (vol/vol) of the prepared alkali solution; bubbling chlorine gas or effluent chlorine gas through the above solution, chlorine gas consumption being 100 to 1000 ml/min, for 6 to 8 h or until brown vapour liberation starts; diluting the mixture with 1.1 to 1.5 parts (vol/vol) of alkali bromine solution and deionised water to obtain a clear solution; evaporating the mixture to obtain a solid product and drying the product at 55 to 80°С.

EFFECT: invention provides for manufacturing non-hazardous solid brominating agent without use of liquid bromine.
