Waikawa Phosphorous，he pūhui parakore me te tātai matū H3PO3. He paura tioata ma, he ngawari ki te wairewa ki te wai me te waiwaro, a ka ngawari te waikura ki te orthophosphate i te hau. Ko te Phosphite he waikawa dibasic, he iti ake te kaha o te waikawa i te waikawa phosphoric, he kaha te whakaheke i nga taonga, he ngawari ki te whakaheke i nga katote hiriwa (Ag+) ki te whakarewa hiriwa (Ag), ka taea te whakaheke i te waikawa sulfuric ki te whanariki hauhā. He kaha hygroscopicity me te deliviousness, a he waikura. Phosphite te nuinga whakamahia rite māngai whakaiti, nairona kaihoko kanapa, engari whakamahia ano rite phosphite raw rauemi, takawaenga pesticide me ūkuikui organic āpiha maimoatanga wai rauemi mata.
Āhuatanga:paura tioata ma. Wairewa ki te wai me te waipiro.Density: 1.651g/cm3, ira whakarewa: 73℃, ira kohua: 200℃.
TONO:
1.Waikawa Phosphorouska whakamahia ki te whakaputa i te tongi phosphate tote penei i te konupora phosphite, te ammonium phosphite me te calcium phosphite. Kei te kaha te whakauru ki te whakarite i nga phosphites rite 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.Waikawa PhosphorousKa taea te whakamahi (H3PO3, waikawa orthophosphorous) 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 ore 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 (ara te cassiterite, ilmenite me te pyrochlore). He iti noa nga korero mo nga mahi a enei kaikohi. Ko nga rangahau iti i mahia me te cassiterite me te rutile ores i whakaatu ko etahi o enei kaikohi ka whakaputa i te hukahuka nui engari he tino whiriwhiri.
Tikanga whakaputa:
Ko nga tikanga whakaputa ahumahi ko te ūkuikui trichloroic me te tote waikawa phosphoric. Ko te tikanga whakamaaramatanga ka ata taapirihia te wai ki te tauhohenga hauwai i raro i te ranu o te trichloride ki te whakaputa waikawa iti-phosphoric. I muri i te whakamahine, te Pukapuka Chemical matao, ka mahia te whakatioatanga me te whakakoi, ka mahia te hua kua oti. Ko tana PCI3+3H2O → H3PO3+3HCL e whakaputa ana i te hangarua hauwai pūhaumāota i roto i te tukanga whakaputa, ka taea te hanga hei waikawa pūhaumāota.
Haumarutanga:
Nga ahuatanga morearea morearea: i roto i te H kohao kaihoko mura; Ka pirau te wera i nga kohu paitini waikura ūkuikui.
Rokiroki me te kawe i nga ahuatanga: te whakamahana o te whare putunga iti te pāmahana maroke; Rokiroki motuhake mai i te kaihoko tuku pore H me te kawakore.
Taapiri: 25kg/Peeke
Rokiroki: Whakaorangia i roto i te kati pai, te rama-atete, me te tiaki i te makuku.
