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]
2001 ― The start of production of dicalcium phosphate. 2002 ― Starts production of mono-calcium phosphate. 2002 ― The majority share package was acquired by Swiss company EuroChem. 2004 ― Starts production of monodicalcium phosphate production. 2007 ― AB "Lifosa" implemented the Project "Utilization of local and recovered process heat ...
The radioactive content of the fertilizers varies considerably and depends both on their concentrations in the parent mineral and on the fertilizer production process. [ 94 ] [ 101 ] Uranium-238 concentrations can range from 7 to 100 pCi/g (picocuries per gram) in phosphate rock [ 102 ] and from 1 to 67 pCi/g in phosphate fertilizers.
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]
Triammonium phosphate can be prepared in the laboratory by treating 85% phosphoric acid with 30% ammonia solution: [citation needed] H 3 PO 4 + 3 NH 3 → (NH 4) 3 PO 4 (NH 4) 3 PO 4 is a colorless, crystalline solid. The solid, which has the odor of ammonia, is readily soluble in water. The salt converts to diammonium hydrogen phosphate (NH 4 ...

A man who returned to his Alaska hometown took to social media to document the inflated prices of food and drinks, including an $11 box of cereal. Still, he says it's someplace he'd live again.
At 200 °C the hexa-phosphate is produced. At 250 °C the typical chain length is 18. Heating hydrated salts induces the loss of ammonia to form oligophosphates and polyphosphates. [3] Diamidophosphate inhibits urease enzymes by blocking up the active site, binding to two nickel centers. Diamidophosphate mimics the urea hydrolysis intermediate. [5]
