Di-Ammonium Phosphate

Di-Ammonium Phosphate (DAP) is a water-soluble ammonium phosphate salt with the chemical formula (NH₄)₂HPO₄. It is commonly used as a high-nitrogen fertilizer and a fire retardant. DAP is highly regarded for its balanced content of nitrogen (N) and phosphorus (P), making it a crucial component in agriculture. It appears as a white or light brown granular or crystalline powder, odorless and non-flammable.

Applications:

1. Agriculture:
   • Used as a high-nitrogen fertilizer, particularly in the early stages of crop growth to promote root development and seedling vigor.
   • Acts as a source of phosphorus for plants, which is essential for energy transfer and photosynthesis.
   • Ideal for use in all soil types and for a wide range of crops, including cereals, fruits, vegetables, and ornamental plants.
2. Fire Retardant:
   • Employed in fire retardant formulations, particularly in forestry and wildfire management, where it helps prevent the spread of flames.
3. Food Additive:
   • Used in the food industry as a yeast nutrient in the fermentation process and as a buffering agent.
4. Water Treatment:
   • Applied in water treatment plants to prevent corrosion in pipes by acting as a corrosion inhibitor.
5. Fermentation Industry:
   • Utilized as a source of nitrogen and phosphorus in the fermentation process for producing beverages, antibiotics, and other products.

Handling and Storage:

• Handling:
  • Avoid contact with skin, eyes, and clothing.
  • Use appropriate personal protective equipment (PPE) such as gloves, goggles, and protective clothing.
  • Ensure good ventilation to avoid inhalation of dust.
  • Handle with care to prevent dust formation, which can cause irritation to the respiratory system.
• Storage:
  • Store in a cool, dry, well-ventilated area away from moisture and incompatible materials.
  • Keep the container tightly closed to prevent moisture absorption, which can cause the product to cake.
  • Store away from strong acids, bases, and oxidizing agents.
  • Ensure proper labeling and keep the product in original packaging.

Safety Considerations:

• Hazard Statements: DAP is generally considered safe, but it can cause eye and skin irritation. Dust may cause respiratory irritation.
• First Aid Measures: In case of contact with skin or eyes, rinse immediately with plenty of water. If inhaled, move to fresh air and seek medical attention if symptoms persist.
