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:
(NH4)2HPO4(s) NH3(g) + NH4H2PO4(s) | log PmmHg = −3063 / T + 175 log T + 3.3 |
