I-Phosphorous Acid, inhlanganisela ye-inorganic ne-chemical formula H3PO3.I-crystalline powder emhlophe, inyibilika kalula emanzini ne-ethanol, futhi kancane kancane i-oxidized ibe i-orthophosphate emoyeni.I-Phosphite iyi-dibasic acid, i-acidity yayo inamandla kancane kune-phosphoric acid, inendawo yokunciphisa eqinile, kulula ukunciphisa ama-ion esiliva (Ag+) kuya kunsimbi yesiliva (Ag), inganciphisa i-sulfuric acid ibe yi-sulfur dioxide.Ine-hygroscopicity eqinile kanye ne-deviousness, futhi iyagqwala.I-Phosphite isetshenziswa kakhulu njenge-ejenti yokunciphisa, i-agent ekhanyisa inayiloni, kodwa futhi isetshenziswa njengezinto zokusetshenziswa ze-phosphite, izibulala-zinambuzane kanye nama-organic phosphorus okwelapha amanzi izinto zokusetshenziswa.
Izakhiwo:i-crystalline powder emhlophe.Incibilika emanzini nasetshwaleni.Ukuminyana: 1.651g/cm3, iphoyinti elincibilikayo: 73℃, iphoyinti elibilayo: 200℃.
ISICELO:
1.I-Phosphorous acidisetshenziselwa ukukhiqiza usawoti womanyolo we-phosphate njenge-potassium phosphite, i-ammonium phosphite ne-calcium phosphite.Ibandakanyeka kakhulu ekulungiseleleni ama-phosphites afana ne-aminotris(methylenephosphonic acid) (ATMP), i-1-hydroxyethane 1,1-diphosphonic acid (HEDP) kanye ne-2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), ethola ukusetshenziswa ekwelapheni amanzi njengesikali noma isivimbeli esonakalisayo.Ibuye isetshenziswe ekuphenduleni kwamakhemikhali njenge-ejenti yokunciphisa.Usawoti wayo, i-lead phosphite isetshenziswa njenge-PVC stabilizer.Ibuye isetshenziswe njengesandulela ekulungiseleleni i-phosphine futhi njengendawo ephakathi ekulungiseni ezinye izinhlanganisela ze-phosphorus.
2.I-Phosphorous acid(i-H3PO3, i-orthophosphorous acid) ingasetshenziswa njengenye yezingxenye zokusabela ekuhlanganiseni okulandelayo:
I-α-aminomethylphosphonic acid nge-Mannich-Type Multicomponent Reaction
I-1-aminoalkanephosphonic acids nge-amidoalkylation elandelwa yi-hydrolysis
I-α-aminophosphonic acid evikelwe nge-N (i-phospho-isosteres yama-amino acid emvelo) ngokusabela kwe-amidoalkylation
3. Ukusetshenziswa kwezimboni:Lo mqoqi wathuthukiswa muva nje futhi wasetshenziswa ngokuyinhloko njengomqoqi othize we-cassiterite ovela ezinsimbini ezinokwakheka kwe-ganggue eyinkimbinkimbi.Ngesisekelo se-phosphonic acid, u-Albright no-Wilson basungule uchungechunge lwabaqoqi ikakhulukazi ukuntanta kwamaminerali ane-oxidic ( okungukuthi i-cassiterite, i-ilmenite ne-pyrochlore).Kuncane kakhulu okwaziwayo mayelana nokusebenza kwalaba baqoqi.Ucwaningo olulinganiselwe olwenziwe nge-cassiterite kanye ne-rutile ores lubonise ukuthi abanye balaba baqoqi bakhiqiza amagwebu agqamile kodwa ayekhetha kakhulu.
Indlela yokukhiqiza:
Izindlela zokukhiqiza zezimboni zihlanganisa i-trichloroic phosphorus kanye nosawoti we-phosphoric acid.Indlela ye-hydrolysis yengeza kancane amanzi ekuphenduleni kwe-hydrolysis ngaphansi kokuxutshwa kwe-trichloride ukuze ikhiqize i-sub-phosphoric acid.Ngemuva kokucwengwa, i-ChemicalBook ebandayo, i-crystallization kanye nokushintsha umbala kwenziwa, futhi umkhiqizo oqediwe uyenziwa.I-PCI3+3H2O yayo → i-H3PO3+3HCL ikhiqiza ukugaywa kabusha kwe-hydrogen chloride phakathi nenqubo yokukhiqiza, engenziwa ibe yi-hydrochloric acid.
Ukuphepha:
Izici zengozi yokuvutha: ku-H hole ejenti evuthayo;Ukushisa kubola intuthu ye-phosphorus oxide enobuthi.
Isitoreji kanye nezici zokuthutha: umoya we-warehouse umoya wokushisa ophansi omile;Gcina ngokuhlukana ne-ejenti ekhipha izimbotshana engu-H kanye ne-alkali.
Ukupakisha: 25kg/Isikhwama
Isitoreji: Londoloza endaweni evalwe kahle, ayizweli ekukhanyeni, futhi uvikele emswakameni.
