Umenzi Ixabiso Elihle lePhosphorous Acid CAS:13598-36-2

Umenzi wexabiso elihle i-Phosphorous Acid CAS:13598-36-2 Umfanekiso obonisiweyo

inkcazo emfutshane:

I-phosphorus acid iphakathi ekulungiseleleni ezinye iikhompawundi ze-phosphorus. I-phosphorus acid sisixhobo esisetyenziswa ekulungiseleleni ii-phosphonates zokunyanga amanzi ezifana nokulawula isinyithi kunye ne-manganese, ukuthintela nokususa isikali, ukulawula ukugqwala kunye nokuzinzisa i-chlorine. Iityuwa zesinyithi ze-alkali (ii-phosphites) ze-phosphorus acid zithengiswa kakhulu njenge-fungicide yezolimo (umz. i-Downy Mildew) okanye njengomthombo obalaseleyo wesondlo se-phosphorus yezityalo. I-phosphorus acid isetyenziswa ekuzinziseni imixube yezinto zeplastiki. I-phosphorus acid isetyenziselwa ukuthintela ubushushu obuphezulu bomphezulu wesinyithi othanda ukugqwala kunye nokuvelisa izinto zokuthambisa kunye nezongezo ze-lubricant.

Inkcazo

I-asidi ye-phosphorus, i-H3PO3, yi-diprotic (ikhawuleza i-ionize ii-proton ezimbini), kungekhona i-triprotic njengoko kunokucetyiswa yile fomula. I-asidi ye-phosphorus iyinxalenye ephambili ekulungiseleleni ezinye ii-compounds ze-phosphorus. Ngenxa yokuba ukulungiswa nokusetyenziswa kwe-"phosphorous acid" kunxulumene kakhulu ne-tautomer enkulu, i-phosphonic acid, idla ngokubizwa ngokuba yi-"phosphorous acid". I-asidi ye-phosphorus inefomyula yekhemikhali i-H3PO3, echazwa ngcono njenge-HPO(OH)2 ukubonisa uphawu lwayo lwe-diprotic.

Ukusetyenziswa kwePhosphorous Acid

1. I-phosphorus acid isetyenziselwa ukuvelisa ityuwa ye-phosphate yesichumiso efana ne-potassium phosphite, i-ammonium phosphite kunye ne-calcium phosphite. Ibandakanyeka ngokukhutheleyo ekulungiseleleni ii-phosphites ezifana ne-aminotris (i-methylenephosphonic acid) (ATMP), i-1-hydroxyethane 1,1-diphosphonic acid (HEDP) kunye ne-2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), ezisetyenziswa kunyango lwamanzi njengesikali okanye i-corrosive inhibitor. Ikwasetyenziswa kwiimpendulo zamakhemikhali njenge-reducing agent. Ityuwa yayo, i-lead phosphite isetyenziswa njenge-PVC stabilizer. Ikwasetyenziswa njengesandulela ekulungiseleleni i-phosphine kwaye njenge-intermediate ekulungiseleleni ezinye ii-phosphorus compounds.
2. I-asidi ye-phosphorus (i-H3PO3, i-orthophosphorous acid) ingasetyenziswa njengenye yeenxalenye zempendulo yokwenza oku kulandelayo:
ii-α-aminomethylphosphonic acids nge-Mannich-Type Multicomponent Reaction
I-1-aminoalkanephosphonic acids nge-amidoalkylation elandelwa yi-hydrolysis
Ii-α-aminophosphonic acids ezikhuselweyo yi-N (ii-phospho-isosteres ze-amino acids zendalo) nge-amidoalkylation reaction
3. Ukusetyenziswa kwemizi-mveliso: Lo mqokeleli uphuhliswe kutshanje kwaye usetyenziswe kakhulu njengomqokeleli othile we-cassiterite evela kwiintsimbi ezidityanisiweyo ezine-gangue complex. Ngokusekelwe kwi-phosphonic acid, u-Albright noWilson baphuhlise uluhlu lwabaqokeleli ikakhulu ukuze bajikeleze iiminerali ze-oxidic (oko kukuthi i-cassiterite, i-ilmenite kunye ne-pyrochlore). Kuncinci okwaziwayo malunga nokusebenza kwaba baqokeleli. Izifundo ezincinci ezenziwe nge-cassiterite kunye ne-rutile ores zibonise ukuba abanye baba baqokeleli bavelisa ulwelo olukhulu kodwa babekhetha kakhulu.
