Abstract

The production process comprises A) forming an acidic aqueous solution comprising alkali metal cations, bromide anions, and sulfamate anions; B) feeding into said aqueous solution a source of alkali metal cations and chlorine-containing bromide oxidant proportioned to keep the resultant aqueous medium acidic and to form an acidic product solution containing at least about 5 wt% of active bromine; and C) raising the pH of the aqueous product solution with water-soluble base to at least about 10.
