Soo saaraha Qiimaha Wanaagsan ee Fosfooraska Acid CAS: 13598-36-2

sharaxaad gaaban:

Fosfooraska Aashitada ayaa dhexdhexaad u ah diyaarinta xeryahooda fosfooraska kale.Fosfooraska aashitada waa walxo ceeriin ah oo loogu diyaariyo fosphonates daaweynta biyaha sida xakamaynta birta iyo manganese, ka hortagga miisaanka iyo saarista, xakamaynta daxalka iyo xasilinta koloriinta.milixda birta ah ee alkali (phosphites) ee fosfooraska aysiidhka ayaa si balaadhan loogu suuq geeyaa sida fungicides-ka beeraha (tusaale Downy Mildew) ama sida isha sare ee nafaqada fosfooraska dhirta.Fosfooraska aashitada waxaa loo isticmaalaa xasilinta isku dhafka walxaha balaastikada ah.Fosfooraska aashitada waxaa loo isticmaalaa in lagu joojiyo heerkulka sare ee meelaha birta ah ee u nugul daxalka iyo in la soo saaro saliidaha iyo kuwa lagu daro.

Sharaxaada

Fosfooraska acid, H3PO3, waa diprotic (si sahal ah ionizes laba borotoons), ma aha triprotic sida laga yaabo in lagu soo jeediyo formula this.Fosfooraska Aashitada ayaa ah dhex dhexaad u ah diyaarinta xeryahooda fosfooraska kale.Sababtoo ah diyaarinta iyo isticmaalka "phosphorous acid" dhab ahaantii waxay ku xiran tahay tautomer-ka weyn, phosphonic acid, waxaa badanaa loo tixraacaa "fosfooraska acid". si ay u muujiso dabeecadeeda diprotic.

Codsiyada Fosfooraska Acid

1.Phosphorous acid waxa loo isticmaalaa in lagu soo saaro milixda fosfooraska bacriminta sida potassium phosphite, ammonium phosphite iyo calcium phosphite.Waxay si firfircoon ugu lug leedahay diyaarinta fosfityada sida aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) iyo 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC) Codsiga daaweynta biyaha sida miisaan ama daxaliyaha.Waxa kale oo loo isticmaalaa falcelinta kiimikaad ahaan wax-yareeya.milixdeeda, fosfit-ka rasaasta rasaasta waxaa loo isticmaalaa sida PVC stabilizer.Waxa kale oo loo isticmaalaa sidii horudhac diyaarinta fosfooraska iyo sida dhexdhexaadka ah ee diyaarinta xeryahooda kale ee fosfooraska.
2.Phosphorous acid (H3PO3, orthophosphorous acid) ayaa laga yaabaa in loo isticmaalo mid ka mid ah qaybaha falcelinta ee isku dhafka kuwan soo socda:
α-aminomethylphosphonic acids iyada oo loo sii marayo falcelinta qaybaha badan ee Mannich-Type
1-aminoalkanephosphonic acids iyada oo loo marayo amidoalkylation oo ay ku xigto hydrolysis
N-ilaaliye α-aminophosphonic acids (phospho-isosteres of amino acids dabiiciga ah) iyada oo loo marayo falcelinta amidoalkylation
3. Isticmaalka warshadaha: Ururiyahan waxaa la sameeyay dhawaan waxaana loo adeegsaday ugu horrayn sida ururiyaha gaarka ah ee cassiterite ka macdano leh Halabuurka gangue adag.On ku salaysan fosfooraska acid ah, Albright iyo Wilson ayaa horumariyo kala duwan oo ka mid ah ururinta inta badan sabaabaynta of macdanta oksida. ie cassiterite, ilmenite iyo pyrochlore).Wax aad u yar ayaa laga og yahay wax qabadka kuwan aruuriya.Daraasado xaddidan oo lagu sameeyay kassiterite iyo macdano rutile ah ayaa muujiyay in qaar ka mid ah kuwan ururiyeyaashu ay soo saaraan maraq mug leh laakiin ay ahaayeen kuwo aad u xulasho ah.
