The sodium bromate is colorless crystals, white particles or crystalline powder and has no odor. Decomposition took place with oxygen evolution at 381 ℃. It is soluble in water, insoluble in ethanol, and neutral. The relative density was 3.34. Used as analytical reagent and oxidant, and hair-waving and dyeing agent. The product is a strong oxidant and is mainly used as a printing and dyeing auxiliary agent; a permanent agent in daily chemicals; can also be used as a chemical reagent; mixing with sodium bromate as gold dissolving agent in gold ore. The production of sodium bromate mainly comprises the traditional electrolytic method, a caustic soda method for reacting bromine and sodium hydroxide, a bromine blowing alkali absorption completion liquid concentration method, an oxychlorination method for reacting lime milk with bromine and chlorine and then carrying out double decomposition reaction with sodium carbonate and the like. At present, manufacturers generally adopt an oxychlorination method for production, and firstly lime milk prepared from lime powder and water is dripped with bromine for reaction to generate calcium bromate and calcium bromide, and then chlorine is introduced for oxidation reaction. Filtering, washing, concentrating the washing liquid, adding barium chloride solution at low temperature to react, washing the barium bromate generated by the reaction with water, performing double decomposition with sodium carbonate, filtering, evaporating, crystallizing, separating and drying to obtain the finished product of sodium bromate.

Sodium bromate with Br₂The initial raw material of the catalyst and NaOH are primarily reacted in a synthesis tank to synthesize NaBr and NaBrO₃Mixing the feed liquid; precipitating and separating part of NaBrO₃Then filtering the mixed feed liquid to remove insoluble impurities, preparing the mixed feed liquid to reach a certain concentration, pumping the mixed feed liquid into an electrolytic bath, oxidizing bromide ions into bromate radicals by direct current, and discharging the bromate radicals after reaching a certain concentration; after evaporation concentration, centrifugation, washing and spin-drying of the electrolysis finished solution, separating out crude sodium bromate, and returning the mother solution to a batching tank for reuse; crude NaBrO₃Dissolving, filtering, evaporating, concentrating, centrifuging, washing and spin-drying; drying the obtained solid to produce high-purity NaBrO₃And (5) finishing.

The last step of current sodium bromate production needs to be dried, and sodium bromate after the drying is the powder, needs to stand six hours in the drying cabinet and slowly cool off, just can transfer to other places after the cooling and deposit, and the drying cabinet is continuously occupied in the cooling process, can't carry out the drying of next batch sodium bromate, has influenced work efficiency, and needs carefully to shift in the transportation, avoids the air current to blow off the powder, and is comparatively troublesome.
