I-Phosphorous Acid,ikhompawundi ezingaphiliyo ezinefomula yeekhemikhali H3PO3.Ingumgubo omhlophe wekristale, unyibilika ngokulula emanzini kunye ne-ethanol, kwaye kancinci i-oxidized kwi-orthophosphate emoyeni.I-Phosphite yi-asidi ye-dibasic, i-acidity yayo yomelele kancinci kune-asidi ye-phosphoric, inepropati eqinile yokunciphisa, kulula ukunciphisa i-ion zesilivere (i-Ag +) kwisinyithi sesilivere (Ag), inokunciphisa i-asidi yesulfuric kwi-sulfur dioxide.Ine-hygroscopicity eyomeleleyo kunye nokukhohlisa, kwaye iyadleka.I-Phosphite isetyenziswa kakhulu njenge-arhente yokunciphisa, i-nayiloni ekhanyayo, kodwa iphinda isetyenziswe njengezinto eziluhlaza ze-phosphite, i-pesticide intermediates kunye ne-organic phosphorus yonyango lwamanzi izinto ezikrwada.
Iinkcazelo ngeempawu:umgubo omhlophe wekristale.Inyibilika emanzini nasetywaleni.Uxinzelelo: 1.651g/cm3, indawo yokunyibilika: 73℃, indawo ebilayo: 200℃.
ISICELO:
1.I-asidi ye-phosphorusisetyenziselwa ukuvelisa ityuwa yephosphate yesichumiso njenge potassium phosphite, ammonium phosphite kunye necalcium phosphite.Ibandakanyeka ngokusebenzayo ekulungiseleleni i-phosphites njenge-aminotris (methylenephosphonic acid) (ATMP), i-1-hydroxyethane 1,1-diphosphonic acid (HEDP) kunye ne-2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), efumana isicelo kunyango lwamanzi njengesikali okanye inhibitor eyingozi.Ikwasetyenziselwa ukuphendula kweekhemikhali njenge-arhente yokunciphisa.Ityuwa yayo, i-phosphite ehamba phambili isetyenziswa njenge-PVC stabilizer.Ikwasetyenziswa njenge-precursor ekulungiseleleni i-phosphine kwaye njengendawo ephakathi ekulungiseleleni ezinye iikhompawundi ze-phosphorus.
2.I-asidi ye-phosphorus(i-H3PO3, i-orthophosphorous acid) inokusetyenziswa njengenye yezinto zokusabela kwi-synthesis yezi zinto zilandelayo:
I-α-aminomethylphosphonic acids nge-Mannich-Type Multicomponent Reaction
I-1-aminoalkanephosphonic acids nge-amidoalkylation elandelwa yi-hydrolysis
I-N-ekhuselweyo i-α-aminophosphonic acids (i-phospho-isosteres yee-amino acids zendalo) ngokusabela kwe-amidoalkylation
3. Ukusetyenziswa kwemizi-mveliso: Lo mqokeleli uphuhliswe kutshanje kwaye wasetyenziswa ngokuyintloko njengomqokeleli othile we-cassiterite evela kwi-ores ene-ganggue eyinkimbinkimbi. Ngokwesiseko se-phosphonic acid, u-Albright noWilson baye baphuhlisa uluhlu lwabaqokeleli ngokukodwa ukujikeleza kweeminerali ze-oxidic. oko kukuthi i-cassiterite, i-ilmenite kunye ne-pyrochlore).Kuncinci kakhulu okwaziwayo malunga nokusebenza kwaba baqokeleli.Izifundo ezilinganiselweyo ezenziwe nge-cassiterite kunye ne-rutile ores zibonise ukuba abanye babaqokeleli bavelisa i-froth voluminous kodwa babekhetha kakhulu.
Indlela yokuvelisa:
Iindlela zokuvelisa i-industrial ziquka i-trichloroic phosphorus kunye netyuwa ye-phosphoric acid.Indlela ye-hydrolysis kancinane yongeza amanzi kwi-hydrolysis reaction phantsi kokuxuba i-trichloride ukuvelisa i-sub-phosphoric acid.Emva kokucocwa, i-ChemicalBook ebandayo, i-crystallization kunye ne-discoloration yenziwa, kwaye imveliso egqityiweyo yenziwe.I-PCI3 + 3H2O yayo → H3PO3 + 3HCL ivelisa i-hydrogen chloride yokuphinda isetyenziswe ngexesha lenkqubo yokuvelisa, enokuthi yenziwe kwi-hydrochloric acid.
Ukhuseleko:
Iimpawu zomngcipheko wokutsha: kwi-H hole arhente enokutsha;Ubushushu bubolisa imisi eyityhefu yephosphorus oxide.
Ukugcinwa kunye neempawu zokuthutha: indawo yokugcina umoya iqondo eliphantsi lobushushu;Gcina ngokwahlukileyo kwi-arhente ekhupha iipore kunye nealkali.
Ukupakisha: 25kg / Isikhwama
Ugcino: Londoloza kwindawo evalwe kakuhle, enganyangekiyo ekukhanyeni, kwaye ukhusele kubumanzi.
