Diammonium Phosphate/ DAP/ (NH4)2HPO4 CAS 7783-28-0

 

Description:
Diammonium Phosphate (DAP) is an inorganic salt that consists of ammonium cations (NH4+) and phosphate anions (PO4³-). It is typically found as a white crystalline powder or granules. DAP is highly soluble in water, allowing for easy application in agricultural practices.

Specification:
Chemical formula: (NH4)2HPO4
Molecular weight: 132.06 g/mol
Appearance: White crystalline powder or granules
Solubility: Highly soluble in water; insoluble in organic solvents
pH (1% solution): Approximately 7
Nitrogen content: Typically around 18%
Phosphorus content: Typically around 46%

Application:

  1. Fertilizer: Diammonium Phosphate is primarily used as a nitrogen-phosphorus fertilizer in agriculture. It provides both essential nutrients, nitrogen and phosphorus, to plants, promoting their growth and development. DAP is suitable for various crops and soil types and is commonly applied as a basal fertilizer or during planting.

  2. Industrial applications: Diammonium Phosphate finds application in various industrial processes, including:

    • Fire extinguishers: DAP is used in certain types of fire extinguishers as a flame-retardant and fire-suppressing agent.
    • Water treatment: It is utilized in water treatment processes to inhibit the growth of algae and improve the quality of water bodies.

Features:

  1. Balanced nutrient content: Diammonium Phosphate contains both nitrogen and phosphorus, essential nutrients for plant growth. The balanced ratio of these nutrients in DAP helps support various stages of plant development.

  2. High solubility: DAP is highly soluble in water, allowing for efficient nutrient uptake by plants and easy application through irrigation systems or as a foliar spray.

  3. Quick-release fertilizer: Diammonium Phosphate provides readily available nitrogen and phosphorus to plants, making it a quick-release fertilizer. This characteristic can deliver immediate nutrient availability for crops.

  4. Versatile application: DAP is suitable for a wide range of crops and can be used in different soil types. It is commonly used in various agricultural systems, including field crops, horticulture, and greenhouse cultivation.

  5. Storage stability: Diammonium Phosphate has good storage stability and is less prone to caking or clumping, ensuring its usability over time.

Application

DAP can be used as fire retardant. It lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an increase in the production of residue or char. These are important effects in fighting wildfires as lowering the pyrolysis temperature and increasing the amount of char formed reduces that amount of avaliable fuel and can lead to the pyrolsis temperature and increasing the amount of some popular commercial firefighting products.

DAP is also used as a yeast nutrient in winemaking and mead brewing; as an additive in some brands of cigarettes purportedly as a nicotine enhancer; to prevent afterglow in matches, in purifying sugar; as a flux for soldering tin, copper, zinc and brass; and to control precipitation of alkali-soluble and acid-insoluble colloidal dyes on wool.
