Phosphoric acid
yog ib hom inorganic acid nrog cov tshuaj formula ntawm H3PO4 thiab molecular hnyav ntawm 97.995. Phosphoric acid tsis yooj yim rau volatilize, tsis yooj yim rau decompose, thiab yuav luag tsis muaj oxidizing zog. Nws muaj cov khoom siv dav dav ntawm cov kua qaub thiab yog ternary tsis muaj zog acid (qee tus hais tias nws yog cov kua qaub nruab nrab). Ntxiv nrog rau kev siv tshuaj reagent, phosphoric acid kuj tseem siv tau hauv cov chaw muag tshuaj, xeb hloov pauv, khoom noj khoom haus additives, cov kuab tshuaj, electrolytes, chiv, metallurgy, pub, thiab lwm yam. Nws kuj tau siv hauv kev kho mob cosmetology thiab kho hniav.
Cov khoom siv dav siv
Phosphoric acid yog yooj yim deliquescent nyob rau hauv cov huab cua, thiab thaum rhuab, nws poob dej los tsim pyrophosphoric acid, uas ntxiv poob dej los tsim metaphosphoric acid.
Silver nitrate thiab protein tuaj yeem siv los txheeb xyuas orthophosphoric acid, metaphosphoric acid, thiab pyrophosphoric acid. Silver nitrate tuaj yeem tsim cov xim daj nyiaj phosphate precipitate nrog orthophosphoric acid, thiab tsim dawb precipitate nrog pyrophosphoric acid thiab metaphosphoric acid, tab sis metaphosphoric acid tuaj yeem precipitate protein.
Phosphoric acid yog siv los ua cov khoom siv raw rau kev tsim cov phosphates. Phosphates yog ntxiv raws li pigments nrog tshwj xeeb functions nyob rau hauv cov xim thiab pigment kev lag luam. Lawv tau ntxiv rau cov xim pleev xim raws li cov khoom siv ntxiv xws li nplaim hluav taws, xeb-pov thawj, tiv thaiv corrosion, hluav taws xob-resistant, antibacterial, thiab luminescent.
Phosphoric acid yog siv los ua cov khoom noj ntxiv thiab ib txwm muaj kev txhawj xeeb rau kev mob pob txha. Cov kev tshawb fawb yav dhau los tau siv cov lus nug los nug cov neeg koom nrog feem ntau lawv haus cov dej haus cola thiab lwm yam dej haus carbonated, thiab pom tias cov neeg haus dej haus carbonated feem ntau yuav muaj mob pob txha.
Tom qab German ua lag luam Polante nrhiav tau phosphorus thiab German chemist Kunkel tsim phosphorus, British chemist Boyle kuj tsim phosphorus ntawm nws tus kheej. Nws kuj yog thawj chemist los kawm txog cov khoom thiab cov tebchaw ntawm phosphorus. Nyob rau hauv nws daim ntawv "Ib sim tshiab ntawm Observed Cold Light" luam tawm nyob rau hauv 1682, nws sau hais tias "phosphorus tsim cov pa luam yeeb dawb tom qab hlawv, thiab cov tshuaj tsim los ntawm cov pa luam yeeb dawb thiab dej yog acidic." Cov pa luam yeeb dawb yog phosphoric anhydride (phosphorus pentoxide), thiab cov tshuaj tsim los ntawm cov tshuaj tiv thaiv nrog dej yog phosphoric acid, tab sis nws tsis tau tshawb fawb ntxiv txog phosphoric acid.
Cov kws tshawb fawb ntxov tshaj plaws los kawm phosphoric acid yog Fab Kis kws tshuaj Lavoisier. Xyoo 1772, nws tau ua qhov kev sim no: phosphorus tau muab tso rau hauv lub thawv tswb kaw nrog mercury kom hlawv. Cov txiaj ntsig kev sim ua rau cov lus xaus hauv qab no: ib qho nyiaj ntawm phosphorus tuaj yeem hlawv hauv qee qhov ntim ntawm huab cua; thaum phosphorus kub hnyiab, cov hmoov dawb ntawm cov phosphorus anhydrous yog tsim, zoo li daus zoo; Tom qab hlawv, huab cua hauv lub raj mis yog li 80% ntawm qhov qub ntim; phosphorus yog kwv yees li 2.5 npaug hnyav dua tom qab hlawv dua li ua ntej hlawv; dawb flakes yaj hauv dej kom tsim phosphoric acid. Lavoisier kuj tau ua pov thawj tias phosphoric acid tuaj yeem tsim los ntawm reacting concentrated nitric acid nrog phosphorus.

Lavoisier kuj tau ua pov thawj tias phosphoric acid tuaj yeem ua tau los ntawm kev ua kom muaj zog nitric acid nrog phosphorus.
Kwv yees li ib puas xyoo tom qab, German chemist Liebig tau ua ntau yam kev ua liaj ua teb chemistry, qhia txog tus nqi ntawm phosphorus thiab phosphoric acid rau cog lub neej. Xyoo 1840, Liebig's "Lub luag haujlwm ntawm Organic Chemistry hauv Kev Ua Liaj Ua Teb thiab Lub Cev" kev tshawb fawb pom tau tias cov av fertility thiab taw qhia lub luag haujlwm ntawm phosphorus ntawm cov nroj tsuag. Nyob rau tib lub sijhawm, nws tau tshawb nrhiav ntxiv txog kev siv phosphoric acid thiab phosphates ua chiv, thiab kev tsim cov phosphoric acid nkag mus rau lub sijhawm ntawm kev tsim khoom loj.

Txij thaum ntawd los, kev tsim cov phosphoric acid nkag mus rau lub sijhawm ntawm kev tsim khoom loj.
