Diammonium phosphate
OPAP offers purchase service to importers and exporters of Diammonium phosphate from Oman and Dubai ports.
Diammonium phosphate (DAP) (chemical formula (NH4)2HPO4, IUPAC name diammonium hydrogen phosphate) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. Solid diammonium phosphate shows a dissociation pressure of ammonia as given by the following expression and equation:[2]
(NH4)2HPO4(s) NH3(g) + NH4H2PO4(s)
log PmmHg = 3063 / T + 175 log T + 3.3
where:
P = the resultant dissociation pressure of ammonia
T = absolute temperature (K)
At 100 C, the dissociation pressure of diammonium phosphate is approximately 5 mmHg.[3]
Accordingly, to MSDS of DiammoniumPhosphate from CF Industries inc. decomposition starts as low as 70*C
"Hazardous Decomposition Products: Gradually loses ammonia when exposed to air at room temperature. Decomposes to ammonia and monoammonium phosphate at around 70�°C (158�°F). At 155�°C (311�°F), DAP emits phosphorus oxides, nitrogen oxides and ammonia."
Uses
DAP is used as a fertilizer.[4] When applied as plant food, it temporarily increases the soil pH, but over a long term the treated ground becomes more acidic than before upon nitrification of the ammonium. It is incompatible with alkaline chemicals because its ammonium ion is more likely to convert to ammonia in a high-pH environment. The average pH in solution is 7.5â??8.[5] The typical formulation is 18-46-0 (18% N, 46% P2O5, 0% K2O).[5]
DAP can be used as a 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.[6] These are important effects in fighting wildfires as lowering the pyrolysis temperature and increasing the amount of char formed reduces that amount of available fuel and can lead to the formation of a firebreak. It is the largest component of some popular commercial firefighting products.[7]
DAP is also used as a yeast nutrient in winemaking and mead-making; 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.[1]

High quality agricultural fertilizers that contains Nitrogen and high phosphorus.
Due to its Granular form it s easy to be used and suitable for all types of crops.
Assist in building protein of the nuclei and in the synthesis of chlorophyll.
Assist in the operations of respiration and the transformation of carbohydrates and fats
representation and has a role in accelerating fruit maturity processes and increases the
resistance to certain diseases.
The Granules dissolve in water on a long time and dissociate slowly in the soil which
increases the effect of phosphorus for the longest time possible, without wasting the
fertilizer in underground water or by any other factors.
Can be mixed with all types of fertilizers and pesticides during use except that contain
calcium.
Chemical Property:
Diammonium phosphate (DAP) is a compound with the chemical formula (NH4)2HPO4. It is a highly soluble salt that appears as a white, crystalline powder. DAP contains two ammonium (NH4+) cations and one hydrogen phosphate (HPO4^2-) anion in its structure. This composition provides a source of both nitrogen and phosphorus, making DAP a valuable fertilizer and nutrient supplement.
Applications:
Diammonium phosphate finds applications primarily in agriculture as a fertilizer, but it also has uses in other industries:
Agriculture and Fertilizers:
DAP is one of the most commonly used fertilizers worldwide. Its high nitrogen content supports plant growth and leaf development, while phosphorus promotes root growth, flowering, and fruiting. The ammonium component of DAP also contributes to pH control in soil, which can be important for optimizing nutrient availability to plants.
Nutrient Supplement:
DAP can be used as a nutrient supplement for both plants and animals. In animal feed, it provides a source of nitrogen and phosphorus, essential for growth and overall health.
Industrial Processes:
DAP is utilized in various industrial applications. For instance, it's used as a fire retardant and flame inhibitor in certain materials due to its ability to release ammonium compounds that resist combustion.
Water Treatment:
In water treatment processes, DAP can be used to reduce pH levels, control scale formation in pipes, and adjust the alkalinity of water.
Yeast Nutrient:
In the brewing and fermentation industries, DAP is used as a nutrient for yeast during the fermentation process. It provides nitrogen necessary for yeast growth and alcohol production.
Laboratory and Research:
DAP is sometimes employed in laboratories for specific applications, such as in the preparation of buffer solutions or as a source of nutrients in cell culture media.
Explosives Manufacturing:
While not a common application, DAP has been used in the production of certain explosives due to its chemical properties.
DAP's versatility stems from its dual nutrient content of nitrogen and phosphorus, making it valuable for promoting plant growth and supporting various industrial processes. When using DAP, it's important to consider proper dosing and application methods to ensure optimal results and minimize any potential environmental impacts.
