Fosfooraska AcidIskudhis aan organic ahayn oo leh qaacidada kiimikada H3PO3.Waa budo crystalline cad, oo si fudud ugu milmay biyaha iyo ethanol, oo si tartiib ah oksijiinta loogu daray orthophosphate hawada.Fosfit waa dibasic acid, aysiidhkeedu wax yar ayuu ka xoog badan yahay fosfooraska, waxa uu leeyahay hanti dhimis xoog leh, fududahay in la dhimo ions silver (Ag+) ilaa birta qalin (Ag), waxa ay yarayn kartaa sulfuric acid ilaa sulfur dioxide.Waxay leedahay hygroscopicity xooggan iyo deliviousness, waana daxal.Phosphite waxaa inta badan loo isticmaalaa sida wakiilka yaraynta, naylon dhalaalka, laakiin sidoo kale loo isticmaalo sida alaabta ceeriin fosfit, dhex dhexaadinta cayayaanka iyo wakiilada daaweynta biyaha fosfooraska organic alaabta ceeriin.
Guryaha:budo crystalline cad.Ku milmay biyaha iyo khamriga. Cufnaanta: 1.651g/cm3, barta dhalaalka: 73 ℃, barta karkarinta: 200 ℃.
CODSIGA:
1.Fosfooraska acidWaxaa loo isticmaalaa in lagu soo saaro cusbada fosfooraska bacriminta sida potassium phosphite, ammonium phosphite iyo fosfit calcium.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.Fosfooraska acid(H3PO3, orthophosphorous acid) waxaa loo isticmaali karaa 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.
Habka wax soo saarka:
Hababka wax soo saarka warshadaha waxaa ka mid ah fosfooraska trichloroic iyo fosfooraska cusbada.Habka hydrolysis-ku wuxuu si tartiib tartiib ah ugu darayaa biyaha falcelinta hydrolysis ee hoos yimaada isku darka trichloride si loo dhaliyo sub-phosphoric acid.Sifeynta ka dib, buug-yare kiimiko qabow, kiristaalka iyo midabaynta ayaa la sameeyaa, badeecada dhammaatayna waa la sameeyaa.PCI3+3H2O → H3PO3+3HCL waxay soo saartaa dib u warshadaynta hydrogen chloride inta lagu jiro habka wax soo saarka, kaas oo laga samayn karo hydrochloric acid.
Amniga:
Sifooyinka halista holcaya: in wakiilka godka H guban kara;Kulaylku wuxuu qurxiyaa qiiqa fosfooraska sunta ah.
Kaydinta iyo sifooyinka gaadiidka: hawo bakhaar heerkul hooseeya oo qallalan;Ku kaydi si ka gooni ah wakiilka H pore-sii daynta iyo alkali.
Xirmooyinka: 25kg/Bac
Kaydinta: Ku ilaali meel si fiican u xidhan, iftiin u adkaysata, kana ilaali qoyaanka.
