6131-90-4 Anhydrous Sodium Acetate White Particle CH₃COONa

International Industrial Grade Sodium Acetate 6131-90-4 White Particle

• Chemical formula: CH₃COONa
• Molecular weight: 82.03 g/mol (anhydrous matter); 136.08 g/mol (trihydrate)
• Structure: Composed of the radical acetate ion (CH₃COO⁻) and sodium ion (Na +)
• pH value: The aqueous solution is weakly alkaline, pH is about 8-9

• Appearance:
  • Anhydrous sodium acetate: white crystalline powder
  • Sodium acetate trihydrate (CH₃COONa*3H₂O): colorless transparent crystal
• Solubility:
  • Soluble in water, solubility increases significantly with temperature (at 20°C, about 46.5 g per 100 mL of water)
  • Slightly soluble in ethanol, insoluble
• Melting point:
  • Anhydrous sodium acetate: 324°C
  • Sodium acetate trihydrate: 58°C (dehydration decomposition)
• Density:
  • Anhydrous sodium acetate: 1.528 g/cm³
  • Sodium acetate trihydrate: 1.45g/cm³
• Hygroscopic: Sodium acetate trihydrate is easy to hygroscopic, and anhydrous sodium acetate hygroscopic is low

Heated decomposition. When heated to high temperatures, sodium acetate decomposes to form sodium carbonate (Na₂CO₃) and methane (CH₄)

• Wear chemical protective gloves, goggles, and lab coats to avoid direct contact with skin and eyes
• Wear a dust mask or respirator in environments where dust or vapor may be generated
• Wash hands thoroughly after use to avoid ingestion or contact with mouth and nose

• Operate in a well-ventilated environment and avoid inhaling dust or steam
• Minimize exposure by operating in enclosed equipment

• Store in an airtight container to avoid moisture absorption and contact with air
• Store in a dry, cool place away from fire and heat
• Store separately from acids, oxidants and food to avoid reactions or contamination

• Use strong, airtight packaging to prevent leaks
• Packaging should be labeled "corrosive" and accompanied by a safety data sheet (SDS)

• Add sodium acetate to water slowly to avoid violent reactions and spillage
• Stir well when preparing the solution to ensure it is completely dissolved

• Sodium acetate reacts with acid to release acetic acid and must be operated in a well-ventilated environment
• Reactions of sodium acetate with strong oxidants can be dangerous

• The waste liquid needs to be neutralized with an acid (such as hydrochloric acid) until it is neutral, and then precipitated
• Barium sulfate is precipitated by adding sulfate, separated and disposed of properly
• After treatment, the waste liquid must meet the environmental protection standards before discharge

• Solid waste should be sealed and packaged and handled by professional institutions
• It is strictly prohibited to discard or discharge sodium acetate waste into the sewer at will

• Rinse with plenty of water for at least 15 minutes to remove contaminated clothing
• If you feel unwell, seek medical attention immediately

• Rinse your eyes with plenty of water for at least 15 minutes, keeping them open
• Seek immediate medical attention

• Quickly move the victim to fresh air
• If breathing is difficult, give artificial respiration
• Seek immediate medical attention

• Gargle immediately, do not induce vomiting
• Seek medical attention immediately and provide a safety data sheet (SDS)

• Use and handling of sodium acetate must comply with local environmental regulations and safety standards
• Try to use alternatives or reduce the amount to reduce the harm to the environment and human body
