Kushandisa zvekurima: mbishi zvinhu zvephosphate fetiraiza uye kudya kunovaka muviri
Indasitiri kushandiswa: makemikari mbishi zvinhu
1.Chengetedza simbi kubva pakuora
2. Yakasanganiswa ne nitric asidhi semakemikari polishing agent kuti ivandudze kupera kwesimbi
3.Material ye phosphatide iyo inoshandiswa kugadzira chigadzirwa chekugeza uye chezvipembenene
4.Kugadzirwa kwe phosphorus ine flameretardant zvinhu.
Zvekuwedzera zvekudya zvinoshandisa: acidic flavour, Yeast Nutri-ents, senge coca-cola.
Kushandiswa kwekurapa: kugadzira mushonga une phos-phorus, senge Na 2 Glycerophosphat
Phosphoric acid kana orthophosphoric acid, chemical formula H3PO4, molecular weight 97.9724, is a common inorganic acid, is a medium strong acid. Inowanikwa nekupedza phosphorus tetroxide mumvura inopisa. Orthophosphoric acid inowanikwa mukutengeserana nekurapa apatite ne sulfuric acid. Phosphoric acid inobvisa mvura nyore mumhepo. Kupisa kunorasa mvura ku pyrophosphoric acid, uyezve kunorasa mvura kuita metaphosphate. Phosphoric acid inonyanya kushandiswa mumishonga, chikafu, fetereza uye mamwe maindasitiri, uye inogona zvakare kushandiswa sekemikari reagent.
Material structure
Orthophosphate iphosphoric asidhi inoumbwa neimwe phospho-oxygen tetrahedron. Mune phosphoric acid molecule, iyo P atomu iri sp3 yakasanganiswa, matatu mahybrid orbitals anoumba matatu sigma bond neatomu reokisijeni, uye imwe P - O bond inoumbwa neiyo sigma bond kubva phosphorus kuenda kuokisijeni uye maviri d-pπ zvisungo kubva. okisijeni kune phosphorus. Chisungo che sigma chinoumbwa nekubatanidzwa kwepeya imwe chete yemaerekitironi kubva paatomu rephosphorous kuenda kune isina munhu orbital yeatomu reokisijeni. d←p bond inoumbwa nekupfuura py uye pz yemaatomu eokisijeni nedxz uye dyz vacant orbitals yemaatomu ephosphorus. Sezvo simba re3d remaatomu ephosphorous rakakwirira kudarika simba re2p remaatomu eokisijeni, mamolecular orbitals haanyanyi kushanda, saka maPO bonds ari mabhondi matatu maererano nenhamba, asi ari pakati pakati peimwe uye kaviri bond maererano nesimba rebhondi. uye bond urefu. Kuvapo kwezvisungo zvehydrogen mune zvese zvakachena H3PO4 uye macrystalline hydrates ayo anogona kuverengera viscosity yephosphoric acid mhinduro.
Nzvimbo yekushandisa
Zvekurima: Phosphoric asidhi chinhu mbishi chekugadzirwa kweakakosha phosphate feteraiza (calcium superphosphate, potassium dihydrogen phosphate, nezvimwewo), uye zvakare yekugadzira chikafu chekudya (calcium dihydrogen phosphate).
Indasitiri: Phosphoric asidhi yakakosha kemikari mbishi zvinhu. Mabasa ayo makuru ndeaya anotevera:
Bata simbi pamusoro kugadzira insoluble phosphate firimu pamusoro simbi pamusoro kudzivirira simbi kubva ngura.
Inoshandiswa sekemikari polish yakasanganiswa ne nitric acid kugadzirisa kupera kwesimbi.
Kugadzirwa kwe detergent, pesticide raw material phosphate ester.
Raw zvinhu zvekugadzirwa kwephosphorous flame retardants.
Chikafu: Phosphoric acid ndeimwe yezvikafu zvinowedzera, muchikafu seyakavava mumiriri, mbiriso inovaka mumiririri, Coca-Cola ine phosphoric acid. Phosphates inokoshawo zvokudya zvinowedzera uye zvinogona kushandiswa sezvokudya zvinowedzera.
Mushonga: Phosphoric acid inogona kushandiswa kugadzira mishonga yephosphorous, yakadai sesodium glycerophosphate.
