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.
Claims6
An acidic aqueous solution with a pH in the range of about 1 to about 6 containing sulfamate and at least about 5 wt % of active bromine.
An acidic aqueous solution with a pH in the range of about 1 to about 6 containing sulfamate and at least about 5 wt % of active bromine, said solution further comprising alkali metal cations and chloride anions.
