KOPO:
1.Phosphorous acide sebelisoa ho hlahisa letsoai la phosphate ea manyolo joalo ka potasiamo phosphite, ammonium phosphite le calcium phosphite.E ameha ka mafolofolo ho lokiseng li-phosphite tse kang aminotris(methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) le 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), e fumanang tshebediso ya pheko ya metsi joalo ka sekala kapa sethiba se senyang.E boetse e sebelisoa liketsong tsa lik'hemik'hale e le ntho e fokotsang.Letsoai la eona, lead phosphite e sebelisoa e le PVC stabilizer.E boetse e sebelisoa e le selelekela sa ho lokisoa ha phosphine hape e le setsi sa ho lokisa metsoako e meng ea phosphorus.
2.Asiti ea phosphorus(H3PO3, orthophosphorous acid) e ka sebelisoa e le e 'ngoe ea likarolo tsa karabelo bakeng sa motsoako oa tse latelang:
α-aminomethylphosphonic acid ka Mannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acid ka amidoalkylation e lateloang ke hydrolysis
N-e sirelelitsoeng α-aminophosphonic acid (phospho-isosteres ea li-amino acid tsa tlhaho) ka karabelo ea amidoalkylation
3. Litšebeliso tsa indasteri: Mokelli enoa o ile a ntlafatsoa haufinyane 'me a sebelisoa haholo-holo e le 'mokelli ea khethehileng oa cassiterite e tsoang ho ores e nang le motsoako o rarahaneng oa gangue.Motheong oa asiti ea phosphonic, Albright le Wilson ba ne ba thehile mefuta e mengata ea ba bokellang haholo-holo bakeng sa ho phalla ha liminerale tsa oxidic. ke hore cassiterite, ilmenite le pyrochlore).Ha ho tsejoe hakaalo ka tšebetso ea babokelli bana.Lithuto tse fokolang tse entsoeng ka li-cassiterite le li-rutile ores li bonts'itse hore ba bang ba babokelli bana ba hlahisa froth e matla empa ba ne ba khetha haholo.
Mokhoa oa tlhahiso:
Mekhoa ea tlhahiso ea indasteri e kenyelletsa trichloroic phosphorus le letsoai la phosphoric acid.Mokhoa oa hydrolysis butle-butle o eketsa metsi ho karabelo ea hydrolysis tlas'a motsoako oa trichloride ho hlahisa sub-phosphoric acid.Kamora ho hloekisoa, ChemicalBook e batang, kristale le ho fifala li entsoe, 'me sehlahisoa se felileng se etsoa.PCI3 + 3H2O ea eona → H3PO3 + 3HCL e hlahisa hydrogen chloride recycling nakong ea tlhahiso, e ka etsoang ka hydrochloric acid.
Tshireletso:
Litšobotsi tsa kotsi ea ho chesa: ho H hole moemeli ea tukang;Mocheso o bolisa mosi o chefo oa phosphorus oxide.
Litšobotsi tsa polokelo le lipalangoang: polokelo ea moea ea ntlo ea polokelo e tlase mocheso o omileng;Boloka ka karohano ho tloha ho H pore-release agent le alkali.
Ho paka: 25kg / Mokotla
Polokelo: Boloka sebakeng se koetsoeng hantle, se thibelang khanya, 'me se sireletse mongobo.
