1.Diammonium phosphate, e lauiloa foi o le diammonium hydrogen phosphate (DAP), o se faʻamaʻi faʻapipiʻi e iai le nitrogen ma le phosphorus.Diammonium hydrogen phosphate ose maualuga maualuga o le faʻaogaina vave o fetilaisa.Ole tusi vaila'au e faigofie ona so'a ile vai ma e itiiti mea malo pe a uma ona fa'amavae.E fetaui lelei mo ituaiga uma o fualaʻau ma eleele, aemaise lava mo fualaʻau e fiafia i le nitrogen ma manaʻomia le phosphorus.E mafai ona faʻaaogaina e fai ma faʻalaʻau faʻavae poʻo le faʻaofuofu pito i luga, ma e talafeagai mo le faʻaogaina loloto.
2.Diammonium phosphate e faasino i le oloa masani, lea e aofia ai le N18% ma le p2o548%.O le foliga tioata e mafolafola ma oblique prism.Ole solubility ile vai ile 25 ℃ ole 71%.O le pH o lona fofo tumu e oʻo atu i le 8, lea e sili atu le maualuga nai lo le monoammonium phosphate chemicalbook.Talu ai ona o le vaifofo tumu o le diammonium phosphate e alkaline, o le faʻaaogaina i le eleele oona e mafai ona faʻaitiitia ai le faʻapipiʻiina o le uʻamea ma le alumini i luga o le phosphorus, ina ia tumau le aoga o le phosphorus.O le mea lea, e fautuaina le diammonium phosphate e faʻaaogaina i le eleele oona.
3.Colorless malamalama monoclinic tioata po o paʻepaʻe paʻepaʻe.Soluble i le vai, e le mafai ona solu i le ava malosi, acetone ma ammonia.
4.I le taimi nei, o auala autu o le gaosiga o fale gaosi oloa e aofia ai le vevela phosphoric acid ma le aveeseina o le phosphoric acid, lea e tali atu i le ammonia vai e maua ai le diammonium hydrogen phosphate.O le muamua e maualuga lona mama ae o le mea mulimuli e taugofie.Fa'amama phosphoric acid neutralization vai ammonia auala fa'afefete le vevela phosphoric acid ma vai fa'amama (vai: phosphoric acid = 1.3: 1) i dilute phosphoric acid, pamu i totonu o le vaega muamua tubular reactor e neutralize i le amonia, pamu le tali tali i le lona lua. tulaga tubular reactor e toe tali atu i le amonia, ina ia oo atu le tau o le pH o le vaifofo tali chemicalbook reverse e uiga i 8.0, faaopoopo arsenic sui sooupu ma uamea mamafa e faamamaina le vaifofo, faamama, ma aveese mea leaga e pei o arsenic ma uamea mamafa, O le filtrate e auina atu i le tane fetuutuunai lelei e fetuutuunai le tau pH i le 7.8 ~ 8.0, auina atu i le evaporator mo le fa'asao ma le fa'atonuga i le maualuga o le 1.3, auina atu i le tioata malulu, malulu ma tioata, centrifuged e vavae ese ai le vai tina. , ma fa'amago ina ia maua ai le oloa mae'a o le edible diammonium hydrogen phosphate.O lona h3po4+2nh3 → (NH4) 2HPO4 .
Fa'atatauga
1.E faʻaaogaina e fai ma faʻaopoopoga meaʻai, faʻafefe afi ma faʻamaʻi afi i totonu o alamanuia
2.As a analytical reagent ma buffer, o se faʻamaluluina faʻamalulu vai fetilaisa maualuga faʻaaogaina lautele i fualaau faisua, fualaau aina, araisa ma saito;Mea'ai fefete, ma isi.
3.I totonu o le alamanuia taumafa, e faʻaaogaina e avea ma sui faʻapipiʻi meaʻai, faʻatonuga paluga, fafaga fefete, ma fesoasoani faʻafefete mo brewing.E mafai ona faʻaaogaina e fai ma faʻamau.
4.As a fafaga chemicalbook faaopoopo mo ruminants.
5.E faʻaaogaina mo le lolomiina o le faia o ipu, vailaʻau, puipuiga o le afi, paipa eletise ma isi faʻamoemoega.Ole vasega ole fa'afugala'au e masani ona fa'aaogaina e pei o le fa'atosina maualuga o le nitrogen ma le phosphorus compound fertilizer.
6.Industrial grade e faʻaaogaina e faʻapipiʻi ai fafie ma ie e faʻateleina ai lo latou tumau;E mafai ona faʻaaogaina e pei o le faʻamago o le paʻu afi afi ma le phosphorus mo lamepa fluorescent;E faʻaaogaina foi i le lolomiina ma le faia o ipu, le gaosiga o paipa eletise, ceramics, enamels, ma isi, ma togafitiga faʻaola ole vai otaota;Fa'agata afi fa'aaogaina e fai ma mea fa'amama vevela o afi afi afi roketi i alamanuia a le militeri.
