Sebenzisa:
Ukusetyenziswa kwezolimo: imathiriyeli ekrwada yesichumiso sephosphate kunye nezondlo zokutya
Ukusetyenziswa kweshishini: imathiriyeli ekrwada yeekhemikhali
1.Khusela intsimbi ekudlekeni
I-2.Ixutywe ne-nitric acid njenge-agent yokupholisa iikhemikhali ukuphucula umphezulu ogqityiweyo wesinyithi
3.Izinto eziphathekayo ze-phosphatide ezisetyenziselwa imveliso yokuhlamba imveliso kunye ne-insecticide
4.Ukuveliswa kwe-phosphorus equlethe izinto ezivuthayo.
Ukusetyenziswa kwezongezo zokutya:incasa eneasidi,Igwele leNutri-ents, ezifana necoca-cola.
Ukusetyenziswa kwezonyango:ukuvelisa iyeza elinephosphorus,enje ngeNa 2 Glycerophosphat
I-asidi ye-phosphoric okanye i-orthophosphoric acid, i-chemical formula H3PO4, i-molecular weight 97.9724, i-asidi ye-inorganic eqhelekileyo, i-asidi eqinile ephakathi. Ifunyenwe ngokunyibilikisa i-phosphorus tetroxide emanzini ashushu. I-Orthophosphoric acid ifumaneka ngokurhweba ngokuphatha i-apatite nge-asidi ye-sulfuric. I-Phosphoric acid ikhupha amanzi ngokulula emoyeni. Ubushushu bulahlekelwa ngamanzi ukuya kwi-pyrophosphoric acid, kwaye ngakumbi ukulahlekelwa ngamanzi kwi-metaphosphate. I-asidi ye-Phosphoric isetyenziswa kakhulu kumachiza, ukutya, izichumisi kunye namanye amashishini, kwaye ingasetyenziswa njenge-reagent yekhemikhali.
Ubume bezinto eziphathekayo
I-Orthophosphate yi-asidi ye-phosphoric eyenziwe yi-tetrahedron enye ye-phospho-oksijeni. Kwimolekyuli ye-phosphoric acid, i-athomu ye-P i-sp3 i-hybridized, i-orbitals ezintathu ezixubileyo zenza iibhondi ezintathu ze-sigma kunye ne-athomu ye-oksijini, kwaye enye i-P - O bond yenziwe ngebhondi enye ye-sigma ukusuka kwi-phosphorus ukuya kwi-oksijini kunye neebhondi ezimbini ze-d-pπ ukusuka. ioksijini kwi-phosphorus. Ibhondi ye-sigma yenziwa ngolungelelwaniso lweperi enye yee-electron ukusuka kwi-athomu ye-phosphorus ukuya kwi-orbital engenamntu ye-athomu ye-oxygen. I-d←p bond yenziwa ngokugqithelana phezu kwe-py kunye ne-pz yee-athom ze-oxygen kunye ne-dxz kunye ne-dyz ye-orbitals ye-athom ye-phosphorus. Ekubeni amandla e-3d e-athomu ye-phosphorus iphezulu kakhulu kune-2p yamandla e-athomu ye-oksijini, i-orbitals ye-molecular ayisebenzi kakuhle, ngoko ke iibhondi ze-PO zibophene kathathu ngokwenani, kodwa ziphakathi phakathi kwe-single kunye ne-double bonds ngokwemigaqo yamandla ebhondi. kunye nobude bombhobho. Ubukho beebhondi ze-hydrogen kuzo zombini i-H3PO4 ecocekileyo kunye ne-crystalline hydrates inokuthi iphendule i-viscosity yesisombululo se-phosphoric acid.
Indawo yosetyenziso
Ezolimo: Iasidi yePhosphoric yimathiriyeli ekrwada yokuvelisa izichumiso zephosphate ezibalulekileyo (icalcium superphosphate, potassium dihydrogen phosphate, njl.), kunye nokuveliswa kwezondlo zokutya (calcium dihydrogen phosphate).
Ishishini: Iasidi yePhosphoric yimathiriyeli ekrwada ebalulekileyo yeekhemikhali. Imisebenzi yayo ephambili yile ilandelayo:
Phatha umphezulu wesinyithi ukuze wenze ifilimu ye-phosphate enganyibilikiyo kwindawo yesinyithi ukukhusela isinyithi kwi-corrosion.
Isetyenziswa njengepolishi yekhemikhali exutywe ne-nitric acid ukuphucula ukugqitywa komphezulu wesinyithi.
Ukuveliswa kwesicoci, isibulali-zinambuzane ekrwada imathiriyeli yephosphate ester.
Imathiriyeli ekrwada yokuveliswa kweeretadants ze-phosphorous flame.
Ukutya: I-Phosphoric acid yenye yezongezo zokutya, ekutyeni njenge-agent ye-flavour emuncu, i-agent ye-yeast nutrition, i-Coca-Cola iqulethe i-asidi ye-phosphoric. I-Phosphates nazo zibalulekile izongezo zokutya kwaye zingasetyenziswa njengeziphuculi zezondlo.
Iyeza: I-asidi ye-Phosphoric ingasetyenziselwa ukwenza amachiza e-phosphorus, njenge-sodium glycerophosphate.
