Process Description
Sodium bromide, chemical formula: NaBr, CAS number: 7647-15-6. An inorganic compound, colorless cubic crystal or white granular powder, odorless, salty and slightly bitter. It easily absorbs moisture and agglomerates in the air, but does not deliquesce. It is easily soluble in water. The aqueous solution is neutral and slightly soluble in ethanol. It can react with dilute sulfuric acid to generate hydrogen bromide. Sodium bromide can be used in photosensitive industry, perfume industry, printing and dyeing industry and other industries. It can also be used in trace determination of cadmium, manufacturing of bromide, inorganic and organic synthesis, photographic paper plates, etc.

Technology comment
Hydrobromic acid and sodium hydroxide carry out a neutralization reaction. After the pH value reaches neutral, the material is discharged through a filter to remove impurities and then sent to the distillation crystallization kettle. It is heated to evaporate the water and then cooled and crystallized. After centrifugation, the finished product is obtained after hot air drying. The core chemical reaction equation of this process flow is: HBr+NaOH→NaBr+H2O.
