KOPO:
1.Asiti ea phosphoruse 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 mokena-pakeng ho lokiseng metsoako e meng ya phosphorus.
2.Asiti ea phosphorus(H3PO3, orthophosphorus 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

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.

Mokhoa oa tlhahiso:
Mekhoa ea tlhahiso ea indasteri e kenyelletsa phosphorus ea trichloroic le letsoai la phosphoric acid. Mokhoa oa hydrolysis o eketsa metsi butle-butle karabelong ea hydrolysis tlas'a motsoako oa trichloride ho hlahisa sub-phosphorus acid. Kamora ho hloekisoa, ChemicalBook e batang, kristale le ho fetoha ha 'mala lia etsoa, 'me sehlahisoa se felileng sea etsoa. PCI3+3H2O → H3PO3+3HCL ea eona e hlahisa hydrogen chloride e sebelisoang hape nakong ea ts'ebetso ea tlhahiso, e ka etsoang hydrochloric acid.
