Abstract
In producing aqueous microbiocidal solutions by oxidation of a water-soluble alkali metal bromide, an intolerable loss of active halogen species has been found to occur during a 10-day period immediately after the product solution has been formed. Surprisingly, this loss has been found to result from an alcohol impurity in the alkali metal bromide used in the process. By eliminating or at least sharply reducing the amount of alcohol impurity in the reaction mixture, products are formed which do not undergo the intolerable loss of active halogen content during the 10-day period.
