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 iyindawo ephakathi ekulungiseni ezinye iikhompawundi zefosphorous.Ngenxa yokuba ukulungiswa kunye nokusetyenziswa kwe "asidi ye-phosphorous" eneneni ibhekiselele kwi-tautomer enkulu, i-asidi ye-phosphonic, idla ngokubizwa ngokuba "yi-asidi ye-phosphorous". ukubonisa uphawu lwayo lwe-diprotic.

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 njenge-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 inhibitor eyingozi.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 uphuhliswe kutshanje kwaye wasetyenziswa ngokuyintloko njengomqokeleli othile we-cassiterite evela kwi-ores ene-ganggue eyinkimbinkimbi. Ngokwesiseko se-phosphonic acid, u-Albright noWilson baye baphuhlisa uluhlu lwabaqokeleli ngokukodwa ukujikeleza kweeminerali ze-oxidic. oko kukuthi i-cassiterite, i-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.
