Kugwiritsa ntchito ndi kugwiritsa ntchito phosphoric acid,
Phosphoric acid, wopanga asidi phosphoric, malangizo opanga phosphoric acid, phosphoric acid chitsanzo, Phosphoric Acid Supplier, Phosphoric acid ndi ntchito yake,
Physicochemical katundu:
1. Zamadzimadzi zowoneka bwino zopanda mtundu, Palibe fungo loyipa
2. Malo osungunuka 42 ℃; kutentha kwa 261 ℃.
3.Kusakanikirana ndi madzi mu chiŵerengero chilichonse
Storge:
1. Sungani m'nyumba yosungiramo zoziziritsa komanso mpweya wabwino.
2. Khalani kutali ndi gwero la moto ndi kutentha.
3. Phukusili ndi losindikizidwa.
4. Iyenera kusungidwa padera ndi zoyaka mosavuta (zoyaka) zoyaka, ma alkali, ndi ufa wachitsulo wokangalika, ndikupewa kusungirako kosakanikirana.
5. Malo osungirako ayenera kukhala ndi zipangizo zoyenera kuti zikhale ndi kutaya.

Gwiritsani ntchito:
Kugwiritsa ntchito paulimi: feteleza wa phosphate ndi zakudya zopatsa thanzi
Kugwiritsa ntchito mafakitale: zopangira mankhwala
1.Tetezani zitsulo kuti zisawonongeke
2.Kusakaniza ndi asidi nitric monga mankhwala kupukuta wothandizila kukonza pamwamba mapeto a zitsulo
3.Zinthu za phosphatide zomwe zimagwiritsidwa ntchito pochapa mankhwala ndi mankhwala ophera tizilombo
4.Kupanga phosphorous yomwe ili ndi zinthu za flameretardant.
Zakudya zowonjezera zimagwiritsidwa ntchito: kununkhira kwa acidic, Yisiti Nutri-ents, monga coca-cola.
Kugwiritsa ntchito kuchipatala: kupanga mankhwala okhala ndi phosphorus, monga Na 2 Glycerophosphat
Phosphoric acid kapena orthophosphoric acid, mankhwala chilinganizo H3PO4, molekyulu kulemera 97.9724, ndi wamba inorganic asidi, ndi sing'anga amphamvu asidi. Amapezeka mwa kusungunula phosphorous tetroxide m'madzi otentha. Orthophosphoric acid imapezeka mwamalonda pochiza apatite ndi sulfuric acid. Phosphoric acid imataya madzi mosavuta mumpweya. Kutentha kumataya madzi kukhala pyrophosphoric acid, ndipo kumataya madzi kukhala metaphosphate. Phosphoric acid imagwiritsidwa ntchito makamaka muzamankhwala, chakudya, feteleza ndi mafakitale ena, komanso ingagwiritsidwe ntchito ngati mankhwala opangira mankhwala.
Kapangidwe kazinthu
Orthophosphate ndi asidi wa phosphoric wopangidwa ndi tetrahedron imodzi ya phospho-oxygen. Mu molekyulu ya phosphoric acid, atomu ya P ndi sp3 wosakanizidwa, ma orbitals atatu osakanizidwa amapanga zomangira zitatu za sigma ndi atomu ya okosijeni, ndipo chomangira china cha P - O chimapangidwa ndi chomangira chimodzi cha sigma kuchokera ku phosphorous kupita ku okosijeni ndi zomangira ziwiri za d-pπ kuchokera. oxygen kuti phosphorous. Chomangira cha sigma chimapangidwa ndi kulumikizana kwa ma electron awiri kuchokera ku atomu ya phosphorous kupita ku orbital yopanda kanthu ya atomu ya okosijeni. d←p bond imapangidwa podutsana py ndi pz ya maatomu okosijeni ndi dxz ndi dyz opanda ma orbitals a maatomu a phosphorous. Popeza mphamvu ya 3d ya maatomu a phosphorous ndi apamwamba kwambiri kuposa mphamvu ya 2p ya maatomu a okosijeni, ma orbitals a molekyulu sagwira ntchito kwambiri, choncho ma PO bond ndi maulendo atatu okhudzana ndi chiwerengero, koma apakati pakati pa mgwirizano umodzi ndi wapawiri potengera mphamvu ya mgwirizano. ndi kutalika kwa bond. Kukhalapo kwa ma hydrogen bond mu H3PO4 yoyera komanso ma crystalline hydrates ake amatha kuwerengera kukhuthala kwa phosphoric acid solution.
Munda wofunsira
Ulimi: Phosphoric acid ndi zopangira zopangira feteleza wofunikira wa phosphate (calcium superphosphate, potassium dihydrogen phosphate, etc.), komanso kupanga zakudya zopatsa thanzi (calcium dihydrogen phosphate).
Makampani: Phosphoric acid ndi chinthu chofunikira kwambiri chamankhwala. Ntchito zake zazikulu ndi izi:
Tetezani zitsulo pamwamba kuti mupange filimu yosasungunuka ya phosphate pamwamba pazitsulo kuti muteteze zitsulo kuti zisawonongeke.
Amagwiritsidwa ntchito ngati opukutira mankhwala osakanikirana ndi nitric acid kuti apititse patsogolo kutha kwa zitsulo.
Kupanga kwa detergent, mankhwala ophera tizilombo phosphate ester.
Zida zopangira zopangira ma phosphorous flame retardants.
Chakudya: Phosphoric acid ndi chimodzi mwazowonjezera chakudya, muzakudya monga wowawasa kununkhira wothandizila, yisiti zakudya wothandizira, Coca-Cola ali phosphoric acid. Phosphates ndi zofunikanso zowonjezera chakudya ndipo angagwiritsidwe ntchito monga zowonjezera michere.
Mankhwala: Phosphoric acid angagwiritsidwe ntchito kupanga mankhwala a phosphorous, monga sodium glycerophosphate.
