Sodium bromide Chemical Properties,Usage,Production

Physical and chemical properties

sodium bromide is a colorless cubic crystal or white granular powder, and belongs to isometric system. It is odorless, and has slightly bitter and briny taste but high toxicity. It is easily to absorb moisture and caking but without deliquescence. It is slightly soluble in alcohol and easily soluble in water (at 100 °C, the solubility in 100ml water solubility is 121g), its aqueous solution is neutral with electronic conductivity. The anhydrous sodium bromide crystal will be precipitated out at 51°C with dihydrate compound forming at temperature lower than 51 °C. Its bromide ion can be substituted by fluorine, and chlorine. Under acidic conditions, it can be oxidized by oxygen and release free bromine; this process is taken advantage of by industry for producing bromine. It can have reaction with dilute sulfuric acid to produce hydrogen bromide. However, hydrobromic acid is a strong acid which can’t be produced through the reaction with dilute sulfuric acid and can only made through high-boiling point acid to make low-boiling point acid. However, we should avoid to use concentrated sulfuric acid which has strong oxidation effect and thus converting bromine (-1) into bromine element and release reddish-brown gas. This method can be used to identify sodium iodide (Heating sodium iodide and concentrated sulfuric acid together will release red-purple gases), Thereby, we can only take the concentrated phosphoric acid together with sodium bromine for heating to produce hydrogen bromine.

Bromide ions can enhance the inhibitor process of brain cortex, and promote their concentration. Therefore, medically it can be used as tranquilizers, and hypnotic or anticonvulsant drugs. When human swallow or inhale the compounds, it will cause harm to central nervous system, brain, and eye while causing irritation response of skin, eyes and also the respiratory tract.

Chemical Properties

Sodium bromide is a colorless cubic crystal or white granular powder. It is odorless, and has slightly bitter and briny taste but high toxicity. It is easily soluble in water (at 100 °C, the solubility in 100ml water solubility is 121g), but slightly soluble in alcohol.

Uses

  • Sodium bromide can be used as raw material in the preparation of liquid photographic film; medically as sedative, the brominating agent in printing and dyeing; it can also be used in synthetic fragrances and other chemicals.
  • Photographic industry applies it for the preparation of liquid photosensitive film. It is medically used for the production of diuretics and sedatives. Perfume industry uses it for the production of synthetic fragrances. Printing and dyeing industry use it as a brominating agent. In addition, it can be also be used for organic synthesis and so on.
  • Sodium bromide is used for the photographic industry, spices, pharmaceutical and printing industries.
  • It is used for the reagents for analysis, and can also be used for the synthesis of inorganic and organic compounds and pharmaceutical industry.
  • It is sued for photographic film, medicines, perfumes, dyes and other industries.
  • It can be applied to determination of trace cadmium and Manufacturing of bromide. It can also be applied to inorganic and organic synthesis, photogravure and pharmaceuticals.

Production method

Urea reduction: dissolve soda ash (sodium carbonate), urea in hot water, and fed into the reactor; gradually add bromine for reaction and generate sodium bromide. Then further add active carbon for decolorization; further undergo filtration, evaporation, crystallization, centrifugal separation, and drying to obtain sodium bromide products. The reaction is as following：
3Br2 + 3Na2CO3 + NH2CONH2 → 6NaBr + 4CO2 ↑ + N2 ↑ + 2H2O
Neutralization method: add about 40% hydrobromic acid into the reactor, stir and slowly add 40% caustic solution for neutralization to Ph 7.5~8 for generating sodium bromide; after isolated by centrifugation, evaporation, crystallization and centrifuged again separation, then we can obtain the final product of sodium bromide. the reaction is:
HBr + NaOH → NaBr + H2O

Toxicity

We should prevent its ingestion and inhalation; avoid the contact of eye and skin with it. If intake or inhalation happens, adverse reactions include dizziness, nausea, and vomiting can occur. In these cases, we should immediately consult a doctor for treatment. Upon being splashed in the eyes, we should immediately rinse with fresh water for 20 min; upon skin contact with sodium bromide, we should also rinse with plenty of water.

Chemical Properties

Sodiumbromide, NaBr,is a white, hygroscopic, crystalline solid with a bitter, saline taste.It is water soluble,with a melting point of 758°C (1400 OF). Sodium bromide is used in medicine as a sedative and in photography in the preparation of silver bromide emulsion on photographic plates or films.

Physical properties

White crystalline powder or granules; saline and slight bitter taste; cubic structure; density 3.20 g/cm3; melts at 747° C; vaporizes at 1,390°C; vapor pressure 1 torr at 806°C and 5 torr at 903°; highly soluble in methanol, 16.7 g/100mL.
The dihydrate is a white crystalline solid; density 2.18 g/cm3; decomposes at 36°C; soluble in water; sparingly soluble in methanol.

Occurrence

Sodium bromide occurs in seawater at an average concentration of 0.008%. It also is found naturally in some salt deposits. It is used in photography for preparing light-sensitive silver bromide emulsions. The salt also is used as a bleaching and disinfecting agent for water treatement in swimming pools, health spas, and hot tubs. Other uses are as a catalyst for partial oxidation of hydrocarbons, for increasing density of aqueous drillng fluids for oil wells, as an electrolyte component in sodium-halogen batteries, as a brominating agent in organic synthesis, in preparing bromide salts, and as a laboratory reagent. Sodium bromide is used in medicine as a sedative and hypnotic.

Uses

Sodium Bromide is a high-tonnage chemical and one of the most important of the bromide salts (NaBr2). High-purity grades are required in the formulation of silver bromide emulsions for photography. The compound, usually in combination with hypochlorites, is used as a bleach, notably for cellulosics. The production of sodium bromide simply involves the neutralization of HBr with NaOH or with sodium carbonate or bicarbonate.

Uses

Sodium Bromide is an inorganic compoiund used as a catalyst in the photoinduced polymerization of acrylates.

Definition

ChEBI: Sodium bromide is an inorganic sodium salt having bromide as the counterion. It is a bromide salt and an inorganic sodium salt. It is used in photographic processingand in analytical chemistry.

Preparation

Sodium bromide can be prepared by several methods. Pure salt can be made by neutralizing sodium hydroxide or sodium carbonate with hydrobromic acid. The solution is evaporated for crystallization:NaOH + HBr → NaBr + H2O NaCO3 + HBr → NaBr + CO2 + H2O
Sodium bromide can be made by passing bromine through an aqueous solution of sodium hydroxide or carbonate in the presence of a reducing agent, such as ammonia, hydrazine, activated charcoal, or Fe2+ ion. A typical method involves adding iron to bromine water to form ferrosoferric bromide, Fe[FeBr5]. This double salt is dissolved in excess water followed by addition of sodium carbonate. The product mixture is filtered and the filtrate is evaporated to crystallize sodium bromide. The overall reaction may be written as follows: 3Fe + 4Br2 + 4Na2CO3 → 8NaBr + FeCO3 + Fe2(CO3)3
Another method involves adding excess bromine to a solution of sodium hydroxide. This forms sodium bromide and bromate. The product solution is evapoated to dryness. The bromate is reduced to bromide by heating with carbon: 3Br2 + 2NaOH + H2O → NaBr + NaBrO3 + 4HBr.

General Description

Sodium bromide is a brominating agent mainly used in organic synthetic reactions as a bromide source.

Hazard

Toxic by inhalation and ingestion.

Flammability and Explosibility

Non flammable

Biochem/physiol Actions

Sodium bromide can be used as a substitute for potassium bromide.

Safety Profile

Moderately toxic by ingestion. Experimental reproductive effects. Incompatible with acids, alkaloidal and heavy-metal salts. When heated to decomposition it emits toxic fumes of Brand NazO. See also BROMIDES.

Purification Methods

Crystallise the bromide from water (0.86mL/g) between 50o and 0o, and dry it at 140o under vacuum (this purification may not eliminate chloride ion).

Incompatibilities

Sodium bromide is compatible with most non-metallic materials of construction such as polypropylene, polyethylene, fiberglass reinforced plastic (FRP), cellulose, cloth, coatings, rubbers, etc. Metals can also be used provided the sodium bromide is kept dry. If the sodium bromide becomes wet, steel will suffer general corrosion and stainless steels and aluminum will suffer pitting attack. The rates of attack will depend upon the amount of oxygen present but in general will not be rapid.
