Mugadziri Mutengo Wakanaka wePhosphorous Acid CAS:13598-36-2

tsananguro pfupi:

Phosphorous acid chinhu chinoshandiswa pakugadzira mamwe ma phosphorous compounds. Phosphorous acid chinhu chinoshandiswa pakugadzira phosphonates dzekuchenesa mvura dzakadai sekutonga iron ne manganese, kudzivirira uye kubvisa scale, kudzora ngura uye kudzikamisa chlorine. Alkali metal salts (phosphites) ye phosphorous acid iri kutengeswa zvakanyanya semushonga wekurima (semuenzaniso Downy Mildew) kana senzvimbo yepamusoro yekudyara phosphorus yezvirimwa. Phosphorous acid inoshandiswa mukusimbisa musanganiswa wezvinhu zvepurasitiki. Phosphorous acid inoshandiswa kudzivirira kupisa kwakanyanya kwesimbi inokurumidza ngura uye kugadzira mafuta ekuwedzera uye mafuta ekuwedzera.

Tsananguro

Asidhi yePhosphorous, H3PO3, idiprotic (inongoisa mapurotoni maviri nyore nyore), kwete triprotic sezvinogona kutaurwa nefomura iyi. Asidhi yePhosphorous ndiyo imwe yenzvimbo dziri pakati pekugadzirwa kwemamwe macompound ephosphorous. Nekuti kugadzirira nekushandiswa kwe "phosphorous acid" zvine chekuita netautomer huru, phosphonic acid, inowanzonzi "phosphorous acid". Asidhi yePhosphorous ine fomura yemakemikari H3PO3, iyo inonyanya kutsanangurwa seHPO(OH)2 kuratidza hunhu hwayo hwe diprotic.

Mashandisirwo ePhosphorous Acid

1. Phosphorous acid inoshandiswa kugadzira phosphate salt yemupfudze yakaita se potassium phosphite, ammonium phosphite uye calcium phosphite. Inobatanidzwa zvakanyanya mukugadzira maphosphites akadai se aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) uye 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), ayo anoshandiswa mukurapa mvura se scale kana corrosive inhibitor. Inoshandiswawo mu chemical reactions se reducing agent. Munyu wayo, lead phosphite inoshandiswa se PVC stabilizer. Inoshandiswawo se precursor mukugadzirira phosphine uye se intermediate mukugadzirira mamwe ma phosphorus compounds.
2. Phosphorous acid (H3PO3, orthophosphorous acid) inogona kushandiswa seimwe yezvikamu zve reaction pakugadzira zvinotevera:
α-aminomethylphosphonic acids kuburikidza neMannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acids kuburikidza ne amidoalkylation ichiteverwa ne hydrolysis
Ma-α-aminophosphonic acids akachengetedzwa neN (phospho-isosteres yemaamino acids echisikigo) kuburikidza neamidoalkylation reaction
3. Mashandisirwo emaindasitiri: Muunganidzi uyu wakagadzirwa nguva pfupi yadarika uye wainyanya kushandiswa semuunganidzi chaiwo we cassiterite kubva mumatombo ane gangue complex. Zvichibva pa phosphonic acid, Albright naWilson vakagadzira mhando dzakasiyana dzemuunganidzi kunyanya dzemuunganidzi we oxidic minerals (kureva cassiterite, ilmenite uye pyrochlore). Zvishoma zvinozivikanwa nezvekushanda kwemuunganidzi uyu. Zvidzidzo zvishoma zvakaitwa ne cassiterite ne rutile ores zvakaratidza kuti vamwe vevaunganidzi ava vanogadzira furo rakawanda asi vaisarudza zvakanyanya.
