Diammonium Phosphate Manufacturing Process

Diammonium phosphate Wikipedia

Diammonium phosphate (DAP) (chemical formula (NH 4) 2 HPO 4, 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:
