Umkhiqizi Intengo Elungile Phosphorous Acid Cas: 13598-36-2

Umkhiqizi Intengo Elungile Phosphorous Acid Chas: 13598-36-2 Kufakwe isithombe

Incazelo emfushane:

I-phosphorous acid iyisigameko lapho kulungiswa ezinye izakhi ze-phosphorous. I-phosphorous acid iyinto eluhlaza okokwenza ama-phosphonates ekwelashweni kwamanzi njengokulawulwa kwensimbi kanye nokuvinjwa, ukukhishwa kwesilinganiso nokususwa, ukulawulwa kokugqwala kanye nokuqina kwe-chlorine. Ama-alkali ensimbi usawoti (ama-phosphis) we-phosphorous acid ayakhangwa kabanzi kungaba njengesikhunta sezolimo (isib. I-Downy hlobo) noma njengomthombo ophakeme wesitshalo phosphorous sokudla okunempilo. I-phosphorous acid isetshenziswa ekuqiniseni izingxube zezinto zokwakha zepulasitiki. I-phosphorous acid isetshenziselwa ukuvimbela izinga lokushisa eliphakeme kakhulu le-coronosing yensimbi yensimbi futhi ikhiqize ama-lifferation kanye nezithasiselo zokugcotshwa.

Ukufanisa

I-phosphorous acid, H3PO3, i-didrotic (kalula ionizes amaprotori amabili), hhayi ama-tripotic angaphakanyiswa yile formula. I-phosphorous acid ingumphakathi lapho kulungiswa ezinye izakhi ze-phosphous. Ngoba ukulungiswa kanye nokusetshenziswa kwe- "phosphorous acid" empeleni kutholakala kakhulu ku-tautomer enkulu, i-phosphonic acid, kuvame ukubizwa ngokuthi "i-phosphorous acid" i-hPPO3, evezwa kangcono njenge-HPO (oh) 2 ukukhombisa umlingiswa wayo we-digrotic.

Izicelo ze-phosphorous acid

I-1.Phosphorous acid isetshenziselwa ukukhiqiza usawoti we-phosphate njenge-potassium phosphite, i-ammonium phosphite ne-photos phosphite ye-calcium. Kubandakanyeka ngenkuthalo lapho kulungiswa ama-phosphis afana ne-aminotris (methylephosphonic acid), 1-hydroxyethane 1,1-phophosbonic acid (hedp) kanye ne-2-phosphobutane-acid (PBTC), okutholayo Isicelo ekuthini ukwelashwa kwamanzi njengesilinganiso noma i-inhibitor esolisayo. Iphinde isetshenziswe ekuphendukeni kwamakhemikhali njenge-ejenti eyengeziwe. Usawoti wayo, i-phosfite yokuhola isetshenziswa njenge-PVC Stabilizer. Iphinde isetshenziswe njenge-preversor lapho kulungiswa i-phosphine futhi njengomphakathi lapho kulungiswa ezinye izinhlanganisela ze-phosphorus.
I-2.phosphorous acid (H3PO3, i-Orthophosphorous acid) ingahle isetshenziswe njengenye yezinto zokuphendula zokuhlanganiswa kokulandelayo:
I-α-aminomethylphosphos acid ngeMannich-Type MultiComponutent Reaction
I-1-amialalcnoneephosphonicid nge-amidoalkylation elandelwa yi-hydrolysis
Ama-Acid we-N-Ampinophonic avikelekile (ama-phospho-ama-ebsereses ama-amino acid wemvelo) nge-amidoalkylation reaction
3. Ukusetshenziswa Kwezimboni: Lo mqoqi wathuthukiswa muva nje futhi wasetshenziswa ngokuyinhloko njengomqokeleli othize we-cassiterite kusuka kububanzi be-cangphonic, i-albright noWilson basungule uhla lwabaqoqi ikakhulukazi ngokugcwala amamineralic ( ie cassiterite, ilmenite kanye ne-pyrocchlechlore). Kuncane kakhulu kwaziwa ngokusebenza kwalaba abaqoqi. Izifundo ezinqunyelwe ezenziwe ngeCassiteiterite ne-rutile ores zibonisa ukuthi abanye balaba baqoqi bakhiqiza i-tuloulinous froth kodwa bakhethe kakhulu.
