Sodium bromate - Preparation Method
Open Data Verified Data
chlorine oxidation method: first, the reaction is carried out by adding bromine Dropwise to lime milk prepared by lime powder and water to generate Calcium bromate and calcium bromide, and then chlorine gas is introduced for oxidation reaction. The filtrate was filtered, washed, and concentrated. The reaction is carried out by adding barium chloride solution at low temperature, and the Barium bromate produced by the reaction is washed with water and then metathesized with sodium carbonate, and then filtered, evaporated, crystallized, separated and dried to obtain a sodium bromate finished product.
