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

inkcazelo emfutshane:

I-asidi ye-phosphorus yinto ephakathi ekulungiseni ezinye iikhompawundi ze-phosphorus. I-asidi ye-Phosphorous yinto eluhlaza ukulungiselela i-phosphonates yonyango lwamanzi njengesinyithi kunye nokulawula i-manganese, ukuvinjelwa kwesikali kunye nokususwa, ukulawulwa kwe-corrosion kunye nokuzinza kwe-chlorine. Iityuwa zesinyithi zealkali (iphosphites) ze-phosphorus acid zithengiswa ngokubanzi njengesibulala-zinambuzane sezolimo (umz. i-Downy Mildew) okanye njengomthombo ogqwesileyo wesondlo se-phosphorus yezityalo. Iasidi yephosphorous isetyenziswa ekuzinziseni imixube kwizinto zeplastiki. Iasidi yePhosphorous isetyenziselwa ukuthintela ubushushu obuphezulu bemigangatho yesinyithi ethanda ukutyiwa kunye nokuvelisa izithambisi kunye nezongezo zokuthambisa.

Inkcazo

I-asidi ye-Phosphorous, i-H3PO3, i-diprotic (i-ionize ngokukhawuleza iiprotoni ezimbini), kungekhona i-triprotic njengoko kunokuphakanyiswa yile fomula. Iasidi yePhosphorous ifana nesiphakathi ekulungiseni ezinye iikhompawundi zefosphorous. Ngenxa yokuba ukulungiswa kunye nokusetyenziswa kwe "asidi ye-phosphorous" eneneni ihambelana kakhulu ne-tautomer enkulu, i-asidi ye-phosphonic, idla ngokubizwa ngokuba "yi-asidi ye-phosphorous".

Ukusetyenziswa kweAcid yePhosphorous

I-1.I-asidi ye-Phosphorous isetyenziselwa ukuvelisa ityuwa ye-phosphate yesichumiso njenge-potassium phosphite, i-ammonium phosphite kunye ne-calcium phosphite. Ibandakanyeka ngokusebenzayo ekulungiseleleni i-phosphites efana ne-aminotris (methylenephosphonic acid) (ATMP), i-1-hydroxyethane 1,1-diphosphonic acid (HEDP) kunye ne-2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), efumana isicelo kunyango lwamanzi njengesikali okanye i-corrosive. Ikwasetyenziselwa ukuphendula kweekhemikhali njenge-arhente yokunciphisa. Ityuwa yayo, i-phosphite ehamba phambili isetyenziswa njenge-PVC stabilizer. Ikwasetyenziswa njenge-precursor ekulungiseleleni i-phosphine kwaye njengendawo ephakathi ekulungiseleleni ezinye iikhompawundi ze-phosphorus.
I-2.I-asidi ye-Phosphorous (H3PO3, i-orthophosphorous acid) ingasetyenziselwa njengenye yezinto ezisabelayo kwi-synthesis yezi zinto zilandelayo:
I-α-aminomethylphosphonic acids nge-Mannich-Type Multicomponent Reaction
I-1-aminoalkanephosphonic acids nge-amidoalkylation elandelwa yi-hydrolysis
I-N-ekhuselweyo i-α-aminophosphonic acids (i-phospho-isosteres yee-amino acids zendalo) ngokusabela kwe-amidoalkylation
3. Ukusetyenziswa kwemizi-mveliso:Lo mqokeleli waphuhliswa mva nje kwaye wasetyenziswa ngokuyintloko njengomqokeleli othile we-cassiterite ukusuka kwi-ores ene-ganggue eyinkimbinkimbi.Ngokwesiseko se-phosphonic acid, u-Albright no-Wilson baphuhlise uluhlu lwabaqokeleli ngokukodwa ukujikeleza kweeminerali ze-oxidic (okt cassiterite, ilmenite kunye ne-pyrochlore). Kuncinci kakhulu okwaziwayo malunga nokusebenza kwaba baqokeleli. Izifundo ezilinganiselweyo ezenziwe nge-cassiterite kunye ne-rutile ores zibonise ukuba abanye babaqokeleli bavelisa i-froth voluminous kodwa babekhetha kakhulu.
