What is di ammonium phosphate used for?
Diammonium phosphate (DAP) is the world’s most widely used phosphorus (P) fertilizer. It is made from two common constituents in the fertilizer industry and it is popular because of its relatively high nutrient content and its excellent physical properties.
What is DAP fertilizer used for?
Agricultural use DAP fertilizer is an excellent source of P and nitrogen (N) for plant nutrition. It’s highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium. A notable property of DAP is the alkaline pH that develops around the dissolving granule.
What does DAP fertilizer contain?
Di-ammonium Phosphate popularly known as DAP is a preferred fertilizer in India because it contains both Nitrogen and Phosphorus which are primary macro-nutrients and part of 18 essential plant nutrients. DAP (NH4)2HPO4: Fertilizer grade DAP Contains 18% Nitrogen and 46% Phosphorus (P2O5)..
Is ammonium phosphate safe?
Inhalation: Breathing mist may cause irritation to the respiratory tract. Eye: May cause irritation, redness, and pain. Skin: May cause irritation to skin. Ingestion: May cause irritation to the gastrointestinal tract and/or nausea.
Is DAP a hazardous?
Unusual Fire & Explosion Hazards: DAP can release toxic and/or irritating ammonia and fluorides when subject to temperatures above 310°F in the presence of water or steam. When dry and heated rapidly, above 310°F, DAP will release ammonia. Cool equipment exposed to fire with water, if it can be done with minimal risk.
Is ammonium phosphate harmful to humans?
May be harmful if inhaled. May cause respiratory tract irritation. Skin May be harmful if absorbed through skin. May cause skin irritation.
What happens if you eat ammonium phosphate?
Ammonium phosphate is an unstable compound made of ammonium and phosphate salt with the chemical formula (NH4)3PO4. Considerable heat is generated which transform the ammonium phosphate sulphate to the molten state.
Is DAP fertilizer flammable?
Explosion hazard : Product is not explosive. Reactivity : Stable at ambient temperature and under normal conditions of use. Firefighting instructions : Keep upwind. Under conditions of fire this material may produce: Ammonia.
Is diammonium phosphate explosive?
Do not induce vomiting. Note to Physicians: No information found. Unusual Fire & Explosion Hazards: DAP can release toxic and/or irritating ammonia and fluorides when subject to temperatures above 310°F in the presence of water or steam.
What is the molecular formula for Di Ammonium Phosphate?
Di-Ammonium Hydrogen Orthophosphate, Ammonium Phosphate Dibasic OR Di-Ammonium Phosphate – (DAP) Product Name Di-Ammonium Phosphate (DAP) IUPAC Name Di-ammonium hydrogen orthophosphate Molecular Formula (NH 4) 2 HPO 4 Molecular Weight 132.1 Appearance White crystalline Powder
How is di ammonium phosphate and hydrogen orthophosphate produced?
Di-Ammonium Hydrogen Orthophosphate, Ammonium Phosphate Dibasic OR Di-Ammonium Phosphate – (DAP) Di-ammonium phosphate (DAP) also known as Di-ammonium hydrogen phosphate is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid until the desired PH is obtained.
Which is the main raw material for Di Ammonium Phosphate?
Di-Ammonium Phosphate GSFC’s Di-Ammonium Phosphate [ (NH4), HPO. (18 % N, 46% P2O5)] plant at Vadodara has a capacity of 2,16,000 TPA. Main raw material for DAP are Sulphur & Rock Phosphate. The main feedstock is Naptha & associated Gas.
What’s the difference between monoammonium phosphate and DAP?
Most field comparisons between DAP and monoammonium phosphate (MAP) show only minor or no differences in plant growth and yield due to P source with proper management. DAP also acts as a fire retardant.
