Umkhiqizi Intengo Enhle I-Phosphorous Acid CAS:13598-36-2

incazelo emfushane:

I-Phosphorous acid iyingxenye emaphakathi ekulungiseni ezinye izinhlanganisela ze-phosphorus.I-Phosphorous acid iyimpahla eluhlaza yokulungisa ama-phosphonates ukuze ahlanzwe amanzi njengokulawula i-iron ne-manganese, ukuvimbela isikali nokususwa, ukulawula ukugqwala kanye nokuqiniswa kwe-chlorine.I-alkali metal salts (phosphites) ye-phosphorus acid idayiswa kabanzi njengesibulala-sikhunta sezolimo (isb. i-Downy Mildew) noma njengomthombo ongcono kakhulu wokondleka kwezitshalo kwe-phosphorus.I-Phosphorous acid isetshenziswa ekuqiniseni izingxube zezinto zepulasitiki.I-Phosphorous acid isetshenziselwa ukuvimbela izinga lokushisa eliphezulu lezindawo zensimbi ezijwayele ukugqwala kanye nokukhiqiza izinto zokuthambisa nezithasiselo zokugcoba.

Incazelo

I-Phosphorous acid, i-H3PO3, i-diprotic (i-ionize kalula ama-proton amabili), ayi-triprotic njengoba kungase kuphakanyiswe yile fomula.I-Phosphorous acid iyingxenye emaphakathi ekulungiseni ezinye izinhlanganisela ze-phosphorus.Ngenxa yokuthi ukulungiswa nokusetshenziswa kwe-“phosphorous acid” empeleni kuthinta kakhulu i-tautomer enkulu, i-phosphonic acid, ngokuvamile ibizwa ngokuthi “i-phosphorous acid”.I-Phosphorous acid inefomula yamakhemikhali i-H3PO3, evezwa kangcono njenge-HPO(OH)2 ukukhombisa uhlamvu lwayo lwe-diprotic.

Ukusetshenziswa kwe-Phosphorous Acid

1.I-Phosphorous acid isetshenziselwa ukukhiqiza usawoti womanyolo we-phosphate njenge-potassium phosphite, i-ammonium phosphite ne-calcium phosphite.Ibandakanyeka kakhulu ekulungiseleleni ama-phosphites afana ne-aminotris(methylenephosphonic acid) (ATMP), i-1-hydroxyethane 1,1-diphosphonic acid (HEDP) kanye ne-2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), ethola ukusetshenziswa ekwelapheni amanzi njengesikali noma isivimbeli esonakalisayo.Ibuye isetshenziswe ekuphenduleni kwamakhemikhali njenge-ejenti yokunciphisa.Usawoti wayo, i-lead phosphite isetshenziswa njenge-PVC stabilizer.Ibuye isetshenziswe njengesandulela ekulungiseleleni i-phosphine futhi njengendawo ephakathi ekulungiseni ezinye izinhlanganisela ze-phosphorus.
I-2.I-Phosphorous acid (H3PO3, i-orthophosphorous acid) ingasetshenziswa njengenye yezingxenye zokusabela ekuhlanganiseni okulandelayo:
I-α-aminomethylphosphonic acid nge-Mannich-Type Multicomponent Reaction
I-1-aminoalkanephosphonic acids nge-amidoalkylation elandelwa yi-hydrolysis
I-α-aminophosphonic acid evikelwe nge-N (i-phospho-isosteres yama-amino acid emvelo) ngokusabela kwe-amidoalkylation
3. Ukusetshenziswa kwezimboni:Lo mqoqi wathuthukiswa muva nje futhi wasetshenziswa ngokuyinhloko njengomqoqi othize we-cassiterite ovela ezinsimbini ezinokwakheka kwe-ganggue eyinkimbinkimbi.Ngesisekelo se-phosphonic acid, u-Albright no-Wilson basungule uchungechunge lwabaqoqi ikakhulukazi ukuntanta kwamaminerali ane-oxidic ( okungukuthi i-cassiterite, i-ilmenite ne-pyrochlore).Kuncane kakhulu okwaziwayo mayelana nokusebenza kwalaba baqoqi.Ucwaningo olulinganiselwe olwenziwe nge-cassiterite kanye ne-rutile ores lubonise ukuthi abanye balaba baqoqi bakhiqiza amagwebu agqamile kodwa ayekhetha kakhulu.
