Sodium Phosphate Tribasic Dodecahydrate (Na₃PO₄·12H₂O)

Sodium Phosphate Tribasic Dodecahydrate (Na₃PO₄·12H₂O) is the dodecahydrate form of sodium phosphate tribasic, meaning it has twelve water molecules associated with each formula unit. It appears as a white, crystalline solid. It is a more hydrated form compared to the anhydrous or less hydrated versions of sodium phosphate tribasic. This form is commonly used in cleaning and industrial applications due to its effective properties as a strong alkaline agent and cleaning booster.

Applications:

1. Cleaning and Detergents:
   • Used as a powerful cleaning agent and water softener in various industrial and household cleaning products.
   • Acts as a builder in detergents to enhance cleaning effectiveness by softening water and improving the performance of surfactants.
2. Water Treatment:
   • Applied in water treatment to prevent scale formation and corrosion.
   • Used to neutralize acidic water and maintain water quality.
3. Food Industry:
   • Used as a food additive (E339) in certain processed foods to control pH levels and as a leavening agent in baking.
4. Industrial Processes:
   • Employed in metal cleaning and processing, paint formulations, and as a flux in metal treatment.
   • Utilized in the production of phosphoric acid and other phosphate derivatives.
5. Laboratory Use:
   • Acts as a buffer solution in laboratory experiments, particularly in biochemical and microbiological applications.

Handling and Safety:

• Personal Protection: Use appropriate protective gear, including gloves, safety goggles, and protective clothing, to avoid skin and eye contact. Use a dust mask or respirator if handling large amounts.
• Inhalation: Avoid inhalation of dust, which may cause respiratory irritation. Work in well-ventilated areas or use local exhaust ventilation.
• Skin/Eye Contact: May cause irritation. Rinse affected areas with plenty of water. Seek medical attention if irritation persists.
• Spills: Carefully sweep or vacuum up material to avoid dust generation. Dispose of according to local environmental regulations.
• First Aid Measures:
  • Inhalation: Move to fresh air. Seek medical attention if irritation or symptoms persist.
  • Skin/Eye Contact: Wash thoroughly with water for at least 15 minutes. Seek medical advice if irritation continues.
  • Ingestion: Rinse mouth and drink plenty of water. Do not induce vomiting. Seek medical help immediately.

Storage:

• Store in a tightly closed container in a cool, dry place to prevent moisture absorption and clumping.
• Keep away from acids and acidic substances to avoid neutralization or chemical reactions.
• Ensure that storage areas are well-ventilated and that the chemical is kept away from heat sources and incompatible materials.

By following these guidelines, you can ensure safe handling and effective use of Sodium Phosphate Tribasic Dodecahydrate.
