Kaihanga Utu Pai Waikawa Phosphorous CAS: 13598-36-2
Whakaahuatanga
Ko te waikawa phosphorous, H3PO3, he diprotic (ka tere te whaka-ionize i ngā porotana e rua), ehara i te triprotic e ai ki tēnei tātai. Ko te waikawa phosphorous he takawaenga i roto i te whakarite i ētahi atu pūhui phosphorous. Nā te mea ko te whakarite me te whakamahinga o te "waikawa phosphorous" e pā ana ki te tautomer matua, te waikawa phosphonic, ka kiia pinepinetia ko te "waikawa phosphorous". Ko te tātai matū o te waikawa phosphorous ko H3PO3, e pai ake te whakapuakina hei HPO(OH)2 hei whakaatu i tōna āhua diprotic.

Ngā Whakamahinga o te Waikawa Phosphorous
1. Ka whakamahia te waikawa phosphorous hei whakaputa i te tote phosphate tongi pērā i te potassium phosphite, te ammonium phosphite me te calcium phosphite. Kei te whai wāhi nui ki te whakarite i ngā phosphite pērā i te aminotris (methylenephosphonic acid) (ATMP), te 1-hydroxyethane 1,1-diphosphonic acid (HEDP) me te 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), e kitea ana te whakamahinga i roto i te maimoatanga wai hei aukati unahi, hei aukati waikura rānei. Ka whakamahia hoki i roto i ngā tauhohenga matū hei kaiwhakaiti. Ko tōna tote, te lead phosphite, ka whakamahia hei whakaū PVC. Ka whakamahia hoki hei matū mua i roto i te whakarite i te phosphine me te takawaenga i roto i te whakarite i ētahi atu matū phosphorus.
2. Ka taea te whakamahi i te waikawa phosphorous (H3PO3, waikawa orthophosphorous) hei wāhanga tauhohenga mō te hanganga o ngā mea e whai ake nei:
Ngā waikawa α-aminomethylphosphonic mā te Tauhohenga Maha-Whāngai Momo-Mannich
Ngā waikawa 1-aminoalkanephosphonic mā te amidoalkylation, ā, muri iho ko te hydrolysis
Ngā waikawa α-aminophosphonic kua tiakina-N (ngā phospho-isosteres o ngā waikawa amino tūturu) mā te tauhohenga amidoalkylation
3. Ngā Whakamahinga Ahumahi: Nō nā tata nei tēnei kaikohi i whakawhanakehia, ā, i whakamahia tuatahitia hei kaikohi motuhake mō te cassiterite mai i ngā konganuku he hanganga gangue matatini. I runga i te waikawa phosphonic, i whakawhanakehia e Albright rāua ko Wilson he whānuitanga o ngā kaikohi, ko te nuinga mō te whakamānu i ngā kohuke oxidic (arā, cassiterite, ilmenite me te pyrochlore). He iti noa iho ngā mōhiotanga mō te mahi a ēnei kaikohi. I whakaatuhia e ngā rangahau iti i mahia ki ngā konganuku cassiterite me te rutile, he nui te pahuka e puta mai ana i ētahi o ēnei kaikohi engari he tino whiriwhiri.
