tlhaloso e khutšoanyane:

Asiti ea phosphorus ke karolo ea bohlokoa ho lokiseng metsoako e meng ea phosphorus. Asiti ea phosphorus ke thepa e tala ea ho lokisa li-phosphonate bakeng sa kalafo ea metsi joalo ka taolo ea tšepe le manganese, thibelo le ho tlosoa ha sekala, taolo ea mafome le ho tsitsisa chlorine. Matsoai a tšepe a alkali (li-phosphite) a phosphorus acid a rekisoa haholo e le sebolaya-mafu sa temo (mohlala, Downy Mildew) kapa e le mohloli o motle oa phepo ea phosphorus ea limela. Asiti ea phosphorus e sebelisoa ho tsitsisa metsoako bakeng sa thepa ea polasetiki. Asiti ea phosphorus e sebelisetsoa ho thibela mocheso o phahameng oa libaka tsa tšepe tse sekametseng ho mafome le ho hlahisa litlolo le lintho tse eketsang mafura.

Tlhaloso

Asiti ea phosphorus, H3PO3, ke diprotic (e ionize proton tse peli habonolo), eseng triprotic joalo ka ha ho ka boleloa ke foromo ena. Asiti ea phosphorus ke karolo ea bohlokoa ho lokiseng metsoako e meng ea phosphorus. Hobane ho lokisoa le tšebeliso ea "asiti ea phosphorus" ha e le hantle ho amana haholo le tautomer e kholo, asiti ea phosphonic, hangata e bitsoa "asiti ea phosphorous". Asiti ea phosphorus e na le foromo ea lik'hemik'hale ea H3PO3, e hlalosoang hantle e le HPO(OH)2 ho bontša semelo sa eona sa diprotic.

Litšebeliso tsa Phosphorous Acid

1. Asiti e nang le phosphorus e sebediswa ho hlahisa letswai la phosphate la manyolo jwalo ka potassium phosphite, ammonium phosphite le calcium phosphite. E ameha ka mafolofolo ho lokiseng diphosphite tse kang aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) le 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), tse sebediswang kalafong ya metsi jwalo ka sekala kapa sethibela-tshenyo. E boetse e sebediswa dikarabelong tsa dikhemikhale jwalo ka moemedi ya fokotsang. Letswai la yona, lead phosphite e sebediswa jwalo ka PVC stabilizer. E boetse e sebediswa jwalo ka selelekela ho lokiseng phosphine le jwalo ka moemedi ho lokiseng metsoako e meng ya phosphorus.
2. Asiti ea phosphorus (H3PO3, orthophosphorous acid) e ka sebelisoa e le e 'ngoe ea likarolo tsa karabelo bakeng sa tlhahiso ea tse latelang:
Li-acid tsa α-aminomethylphosphonic ka Karabelo ea Mannich-Type Multicomponent
Li-aminoalkanephosphonic acid tse 1 ka amidoalkylation li lateloa ke hydrolysis
Li-aminophosphonic acid tse sirelelitsoeng ke N (li-phospho-isoster tsa li-amino acid tsa tlhaho) ka karabelo ea amidoalkylation
3. Tšebeliso ea indasteri: Moqokeleli enoa o sa tsoa ntlafatsoa 'me o ne a sebelisoa haholo-holo e le moqokeleli ea khethehileng bakeng sa cassiterite ho tsoa lirafshoeng tse nang le motsoako o rarahaneng oa gangue. Motheong oa asiti ea phosphonic, Albright le Wilson ba ne ba thehile mefuta e fapaneng ea baqokeleli haholo-holo bakeng sa ho phaphamala ha liminerale tsa oxidic (ke hore cassiterite, ilmenite le pyrochlore). Ho tsejoa hanyane haholo ka ts'ebetso ea baqokeleli bana. Lithuto tse fokolang tse entsoeng ka lirafshoa tsa cassiterite le rutile li bontšitse hore tse ling tsa baqokeleli bana li hlahisa lerōle le leholo empa li ne li khetha haholo.
