Ukusetshenziswa kwezolimo:izinto ezingavuthiwe zomanyolo we-phosphate kanye nezakhamzimba zokudla
Ukusetshenziswa kwemboni: izinto zokusetshenziswa zamakhemikhali
1.Vikela insimbi ekugqwaleni
2.Ihlanganiswe ne-nitric acid njenge-ejenti yokupholisha ngamakhemikhali ukuze kuthuthukiswe isiphetho esingaphezulu sensimbi
3.Impahla ye-phosphatide esetshenziselwa umkhiqizo wokuwasha kanye nesibulala-zinambuzane
4.Ukukhiqizwa kwe-phosphorus equkethe izinto ze-flameretardant.
Ukusetshenziswa kwezithasiselo zokudla:isinongo esine-acidic,I-Yeast Nutri-ents, njenge-coca-cola.
Ukusetshenziswa kwezokwelapha:ukukhiqiza umuthi oqukethe iphosphorus,njengeNa 2 Glycerophosphat
I-Phosphoric acid noma i-orthophosphoric acid, ifomula yamakhemikhali i-H3PO4, isisindo samangqamuzana angu-97.9724, i-asidi evamile ye-inorganic, iyi-asidi eqinile ephakathi. Itholakala ngokuncibilikisa i-phosphorus tetroxide emanzini ashisayo. I-Orthophosphoric acid itholakala ngokuthengisa ngokwelapha i-apatite nge-sulfuric acid. I-Phosphoric acid iqeda amanzi kalula emoyeni. Ukushisa kulahlekelwa amanzi ku-pyrophosphoric acid, futhi kuphinde kulahlekelwe amanzi abe yi-metaphosphate. I-Phosphoric acid isetshenziswa kakhulu kwezemithi, ekudleni, kumanyolo nakwezinye izimboni, futhi ingasetshenziswa njenge-reagent yamakhemikhali.
Isakhiwo sezinto ezibonakalayo
I-Orthophosphate iyi-asidi ye-phosphoric eyakhiwe nge-tetrahedron eyodwa ye-phospho-oksijeni. Ku-molecule ye-phosphoric acid, i-athomu ye-P i-sp3 hybridized, ama-orbitals amathathu ayi-hybrid akha amabhondi amathathu e-sigma ne-athomu yomoya-mpilo, kanti enye ibhondi engu-P - O yenziwe ngebhondi eyodwa ye-sigma esuka ku-phosphorus iye kumoya-mpilo kanye namabhondi amabili e-d-pπ oksijini kuya ku-phosphorus. Ibhondi ye-sigma yakhiwa ngokudidiyela kwepheya eyodwa yama-electron ukusuka ku-athomu ye-phosphorus kuya ku-orbital engenalutho ye-athomu yomoya-mpilo. I-d←p bond yenziwa ngokweqa i-py ne-pz yama-athomu omoya-mpilo ne-dxz ne-dyz yama-orbitals angenalutho yama-athomu e-phosphorus. Njengoba amandla angu-3d we-athomu ye-phosphorus ephakeme kakhulu kunamandla we-2p we-athomu ye-oxygen, ama-orbitals e-molecular awasebenzi kahle kakhulu, ngakho-ke amabhondi e-PO angamabhondi amathathu ngokwenombolo, kodwa aphakathi phakathi kwe-single kanye ne-double bond ngokuya kwamandla ebhondi. kanye nobude bebhondi. Ukuba khona kwamabhondi e-hydrogen kukho kokubili okuhlanzekile kwe-H3PO4 kanye nama-hydrates ayo e-crystalline kungase kubangele i-viscosity yesisombululo se-phosphoric acid.
Inkambu yohlelo lokusebenza
Ezolimo: I-Phosphoric acid iyimpahla eluhlaza yokukhiqiza umanyolo we-phosphate obalulekile (i-calcium superphosphate, i-potassium dihydrogen phosphate, njll.), kanye nokukhiqizwa kwezakhi zokudla (i-calcium dihydrogen phosphate).
Imboni: I-Phosphoric acid iyi-chemical material eluhlaza. Imisebenzi yayo eyinhloko imi kanje:
Phatha indawo yensimbi ukuze udale ifilimu ye-phosphate engancibiliki endaweni yensimbi ukuze uvikele insimbi ekugqwaleni.
Isetshenziswa njengepholishi yamakhemikhali exutshwe ne-nitric acid ukuze kuthuthukiswe isiphetho sendawo yensimbi.
Ukukhiqizwa kwe-detergent, isibulala-zinambuzane eluhlaza i-phosphate ester.
Izinto zokusetshenziswa zokukhiqiza ama-phosphorous flame retardants.
Ukudla: I-Phosphoric acid ingenye yezithako zokudla, ekudleni njenge-ejenti yokunambitheka okumuncu, i-ejenti yokudla okunomsoco, i-Coca-Cola iqukethe i-phosphoric acid. Ama-Phosphates nawo ayizithasiselo zokudla ezibalulekile futhi angasetshenziswa njengezithuthukisi zomsoco.
Umuthi: I-Phosphoric acid ingasetshenziswa ukwenza izidakamizwa ze-phosphorous, njenge-sodium glycerophosphate.
