Diammonium phosphate (DAP; IUPAC name diammonium hydrogen phosphate; chemical formula (NH 4) 2 (HPO 4)) 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]
The annual demand for phosphate as a fertilizer nutrient in 2014 is projected to be over 44 million tonnes, sold primarily as monoammonium phosphate (MAP) and diammonium phosphate (DAP).
The large production of sulfuric acid is primarily motivated by this application. [38] In the nitrophosphate process or Odda process (invented in 1927), phosphate rock with up to a 20% phosphorus (P) content is dissolved with nitric acid (HNO 3) to produce a mixture of phosphoric acid (H 3 PO 4) and calcium nitrate (Ca(NO 3) 2).
Ammonium dihydrogen phosphate (ADP), also known as monoammonium phosphate (MAP) [5] is a chemical compound with the chemical formula (NH 4)(H 2 PO 4). ADP is a major ingredient of agricultural fertilizers [6] and dry chemical fire extinguishers. It also has significant uses in optics [7] and electronics. [8]
Example of a calcium feed phosphate production. Phosphoric acid is neutralized by means of calcium oxide or calcium carbonate, or a mixture of them. Dicalcium phosphate: H 3 PO 4 + CaO + H 2 O ↔ CaHPO 4 + 2 H 2 O Monocalcium phosphate: 2H 3 PO 4 + CaO + H 2 O ↔ Ca(H 2 PO 4) 2.H 2 O + H 2 O Or : Based on dicalcium phosphate
