KOPO:
1.Phosphorous acide sebelisoa ho hlahisa letsoai la phosphate ea manyolo joalo ka potasiamo phosphite, ammonium phosphite le calcium phosphite. E kenya letsoho 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 ts'ebeliso ea phekolo ea metsi e le tekanyo kapa e 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.Phosphorous acid(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

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 ho tloha 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).

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.
