Kaihanga Pai Utu Phosphorous Acid CAS:13598-36-2
Whakaahuatanga
Ko te waikawa Phosphorous, H3PO3, he diprotic (ka katote i nga protons e rua), ehara i te triprotic pera i te whakaaro o tenei tauira.Ko te waikawa Phosphorous hei takawaenga ki te whakarite i etahi atu puhui phosphorous.Na te mea ko te whakarite me te whakamahinga o te "waikawa phosphorous" e pa ana ki te tautomer nui, te waikawa phosphonic, ka kiia ko "waikawa phosphorous". hei whakaatu i tona ahua diprotic.

Nga tono mo te waikawa Phosphorous
1.Ka whakamahia te waikawa Phosphorous ki te whakaputa i te tongi phosphate tote rite te pāhare pāporo phosphite, te haukinia phosphite me te konupūmā phosphite.Kei te kaha te whai waahi ki te whakarite i nga phosphites penei i te aminotris(methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) me te 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), e kitea ana. te tono i roto i te maimoatanga wai hei tauine, hei aukati kino ranei.Ka whakamahia ano i roto i nga tauhohenga matū hei kaihoko whakaheke.Ko tana tote, ka whakamahia te phosphite mata hei whakapumau PVC.Kei te whakamahia ano hoki hei tohu i roto i te whakarite o te phosphine me te takawaenga ki te whakarite i etahi atu puhui ūkuikui.
2.Ka taea te whakamahi i te waikawa Phosphorous (H3PO3, orthophosphorous acid) hei waahanga tauhohenga mo te whakahiato o enei e whai ake nei:
α-aminomethylphosphonic acids mā te Mannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acids na roto i te amidoalkylation whai muri i te hydrolysis
Nga waikawa α-aminophosphonic kua parea-N (nga phospho-isosteres o nga waikawa amino maori) ma te tauhohenga amidoalkylation
3. Whakamahinga Ahumahi: I whakawhanakehia tenei kaikohi i mua tata nei ka whakamahia hei kaikohi motuhake mo te cassiterite mai i nga ores me te hanganga gangue uaua. I runga i te waikawa phosphonic, i whakawhanakehia e Albright raua ko Wilson te whānuitanga o nga kaikohi i te nuinga mo te rere o nga kohuke waikura ( arā te cassiterite, te ilmenite me te pyrochlore).He iti noa nga korero mo te mahi a enei kaikohi.Ko nga rangahau iti i whakahaeretia me te cassiterite me te rutile ores i whakaatu ko etahi o enei kaikohi ka whakaputa i te hukahuka nui engari he tino whiriwhiri.
