Description

Sodium Bromide (NaBr) is a white, crystalline powder known for its wide-ranging applications in various industries, especially pharmaceuticals, water treatment, and oil drilling. As a highly soluble and stable compound, sodium bromide plays a significant role in chemical processes requiring a reliable source of bromide ions.

Chemical Properties of Sodium Bromide

• Molecular Formula: NaBr

• Molar Mass: 102.89 g/mol

• Appearance: White crystalline or powdered solid

• Solubility: Highly soluble in water and alcohol

• Melting Point: 755 °C

• Boiling Point: 1,390 °C

Sodium bromide is a neutral salt, formed by the reaction of sodium hydroxide (NaOH) and hydrobromic acid (HBr). In powdered form, it offers easier handling and faster dissolution, making it preferred for specific industrial processes.

Key Applications of Sodium Bromide Powder

1. Oil and Gas Drilling
   Sodium bromide is a key component in clear brine fluids used for well completion and workover operations. Its high-density properties help control pressure and stabilize the wellbore.

2. Pharmaceutical Industry
   Historically, sodium bromide was used as a sedative and anticonvulsant. Though less common today in human medicine, it’s still employed in veterinary formulations.

3. Water Treatment
   In combination with chlorine or ozone, sodium bromide helps in generating hypobromous acid, an effective disinfectant for cooling towers, swimming pools, and spas.

4. Photography
   Sodium bromide is used in photographic processing to manufacture light-sensitive emulsions.

5. Chemical Manufacturing
   Acts as a source of bromide ions in organic synthesis and other bromine-related reactions.

Advantages of Using Sodium Bromide Powder

• Quick dissolution in solvents

• Consistent particle size and purity

• Stable storage and long shelf-life

• Suitable for high-precision applications

Safety and Handling

While sodium bromide is relatively non-toxic compared to other bromide compounds, proper handling is essential:

• Storage: Keep in a cool, dry place, away from incompatible materials like strong acids.

• Personal Protection: Use gloves, safety glasses, and appropriate dust protection.

• Inhalation or Ingestion: May cause irritation; seek medical help if exposure occurs.

• Environmental Impact: Should be handled to prevent release into the environment, especially water sources.

Conclusion

Sodium Bromide Powder is a versatile and valuable chemical, offering reliable performance across industries such as oil drilling, pharmaceuticals, and water treatment. Its ease of use and efficiency make it a preferred choice for applications requiring high-purity bromide ions.
