PROCESS FOR PRODUCING AMMONIUM BROMIDE
The invention relates to chemical technology pertaining to mineral salts and can be used in the chemical industry. A process for producing ammonium bromide from a bromide-containing polycomponent hydromineral feedstock includes: two-stage oxidation of bromide ions using gaseous chlorine during acidification of a brine; air desorption of elementary bromide; absorption of same using a cooled solution of ammonium bromide; and reduction using an ammonia solution. The resulting concentrate of ammonium bromide is evaporated until crystals are formed. The ammonium bromide crystals are dried and the mother liquor is used to produce a solution of ammonium bromide as a commercial product.
PROCESS FOR REDUCING THE CORROSIVENESS OF A BIOCIDAL COMPOSITION CONTAINING IN SITU GENERATED SODIUM HYPOCHLORITE
A process for substantially reducing the corrosiveness of a composition containing in situ generated sodium hypochlorite in which the sodium hypochlorite is substantially converted to a haloamine.
