Asiidh Fosfooraska ahIsku-darka aan organic-ga ahayn oo leh qaacidada kiimikada H3PO3. Waa budo cad oo crystalline ah, si fudud ugu milmi karta biyaha iyo ethanol, si tartiib tartiib ahna ugu oksaydhsanaysa orthophosphate hawada. Phosphite waa asiidh dibasic ah, asiidhkeedu wuu ka xoog badan yahay fosforic acid, wuxuu leeyahay sifooyin yareeya xoog badan, si fudud ayaa loo dhimi karaa ion-yada qalinka (Ag+) ilaa birta qalinka (Ag), wuxuu yareyn karaa asiidhka sulfuric una beddeli karaa sulfur dioxide. Waxay leedahay hygroscopicity iyo dhadhan xoog leh, waana daxal. Phosphite waxaa inta badan loo isticmaalaa sidii wakiil yareeya, wakiil iftiimiya nayloon, laakiin sidoo kale waxaa loo isticmaalaa sidii walxo cayriin ah oo fosfooraska ah, dhexdhexaadiyeyaasha cayayaanka iyo wakiilada daaweynta biyaha ee fosfooraska dabiiciga ah walxaha ceeriin.
Guryaha:Budada cad ee kiristalline-ka ah. Ku milma biyaha iyo khamriga. Cufnaanta: 1.651g/cm3, dhibic dhalaalid: 73℃, dhibic karkaraya: 200℃.
CODSIGA:
1.Aashitada fosfooraskawaxaa loo isticmaalaa in lagu soo saaro milixda bacriminta ee fosfate sida potassium phosphite, ammonium phosphite iyo calcium phosphite. Waxay si firfircoon ugu lug leedahay diyaarinta phosphites sida aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) iyo 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), kuwaas oo loo adeegsado daaweynta biyaha sidii daawo miisaan ama daxal ah. Waxaa sidoo kale loo isticmaalaa falcelinta kiimikada sida wakiil yareeya. Cusbo, fosfite-ka rasaasta waxaa loo isticmaalaa sidii xasiliye PVC ah. Waxaa sidoo kale loo isticmaalaa sidii horudhac diyaarinta phosphine iyo dhexdhexaad diyaarinta iskudhisyada kale ee fosfooraska.
2.Aashitada fosfooraska(H3PO3, aashitada orthophosphorous) waxaa loo isticmaali karaa mid ka mid ah qaybaha falcelinta ee isku-darka kuwan soo socda:
Asiidhyada α-aminomethylphosphonic iyada oo loo marayo Falcelinta Qaybaha Badan ee Mannich-Type
1-aminoalkanephosphonic acids iyada oo loo marayo amidoalkylation oo ay ku xigto hydrolysis
Asiidhyada α-aminophosphonic ee N-ilaaliya (phospho-isosteres ee amino acids dabiiciga ah) iyada oo loo marayo falgalka amidoalkylation
3. Isticmaalka warshadaha: Ururiyahan waxaa dhawaan la sameeyay waxaana loo isticmaalay inuu noqdo ururiyaha gaarka ah ee cassiterite laga soo bilaabo macdanta leh halabuurka gangue ee adag. Iyada oo lagu saleynayo fosfonic acid, Albright iyo Wilson waxay sameeyeen noocyo kala duwan oo ururiyayaal ah oo inta badan loogu talagalay sabbeynta macdanta oksaydhka (tusaale ahaan cassiterite, ilmenite iyo pyrochlore). Wax yar ayaa laga ogyahay waxqabadka ururiyayaashan. Daraasado kooban oo lagu sameeyay macdanta cassiterite iyo rutile ayaa muujiyay in qaar ka mid ah ururiyayaashu ay soo saaraan xumbo badan laakiin aad u xulasho badan.
Habka wax soo saarka:
Hababka wax soo saarka warshadaha waxaa ka mid ah fosfooraska trichloroic iyo milixda fosfooraska. Habka hydrolysis-ka ayaa si tartiib tartiib ah ugu daraya biyo falgalka hydrolysis-ka iyadoo la isku darayo trichloride-ka si loo soo saaro aashitada sub-phosphoric. Ka dib marka la nadiifiyo, ChemicalBook qabow, crystallization-ka iyo isbeddelku waa la sameeyaa, ka dibna badeecada la dhammeeyay ayaa la sameeyaa. PCI3+3H2O → H3PO3+3HCL waxay soo saartaa dib-u-warshadaynta hydrogen chloride inta lagu jiro habka wax soo saarka, taas oo laga samayn karo hydrochloric acid.
Amniga:
Astaamaha khatarta gubashada: walxaha H ee guban kara; Kulaylku wuxuu burburiyaa qiiqa sunta ah ee fosfooraska oksaydhka.
Astaamaha kaydinta iyo rarista: hawo-qaadista bakhaarka heerkul hoose oo qalalan; Kaydso si gaar ah wakiilka sii daaya daloolka H iyo alkali.
Baakad: 25kg/Bac
Kaydinta: Ku kaydi meel si fiican u xiran, iftiin u adkaysta, kana ilaali qoyaanka.
