Diammonium phosphate, tseem hu ua diammonium hydrogen phosphate, diammonium phosphate, yog xim tsis muaj pob tshab pob tshab monoclinic siv lead ua lossis hmoov dawb. Qhov txheeb ze ntom yog 1.619. Yooj yim soluble hauv dej, insoluble hauv cawv, acetone, thiab ammonia. Rho tawm thaum rhuab mus rau 155 ° C. Thaum raug rau huab cua, nws maj mam poob ammonia thiab dhau los ua ammonium dihydrogen phosphate. Cov tshuaj aqueous yog alkaline, thiab pH tus nqi ntawm 1% kev daws teeb meem yog 8. Tshuaj tiv thaiv nrog ammonia los tsim triammonium phosphate.
Cov txheej txheem ntau lawm ntawm diammonium phosphate: Nws yog tsim los ntawm kev ua ntawm ammonia thiab phosphoric acid.
Kev siv cov diammonium phosphate: siv los ua hluav taws kub rau cov chiv, ntoo, ntawv, thiab ntaub, thiab tseem siv rau hauv cov tshuaj, qab zib, pub additives, poov xab thiab lwm yam.
Nws maj mam poob ammonia hauv huab cua thiab ua ammonium dihydrogen phosphate. Cov dej-soluble sai ua yeeb yam chiv siv hauv cov av ntau thiab ntau yam qoob loo. Nws tuaj yeem raug siv los ua noob chiv, hauv paus chiv thiab hnav khaub ncaws sab saum toj. Tsis txhob sib tov nws nrog cov roj ntsha alkaline xws li tsob ntoo tshauv, txiv qaub nitrogen, txiv qaub, thiab lwm yam, yog li kom tsis txhob txo cov chiv ua kom muaj zog.
