I-phosphorous acid, I-Inorganic Compound ngefomula yamakhemikhali H3PO3. Kuyimpuphu emhlophe ye-crystalline, ukuncibilika kalula emanzini nase-ethanol, futhi kufakwe kancane kancane ungene ku-orthophophosphate emoyeni. I-Phosphite i-dibasic acid, i-acidity yayo inamandla kancane kune-phosphoric acid, kulula ukunciphisa impahla yesiliva (i-AG +) kuya ku-sulfuric metal (ag), inganciphisa i-sulfuric acid ku-sulfur dioxide. Inokuhlaziywa okuqinile nokukhohlisa, futhi kuyawohloka. I-Phosfute isetshenziswa ikakhulukazi njengokunciphisa i-ejenti, i-ejenti yokuqhakambisa i-nylon, kodwa futhi isetshenziswa njengezinto zokwenziwa kwezinto ezivuthayo ze-phosfite, ama-pesticide ahlukahlukene ama-ejenti we-organic phosphorus athents agents izinto ezisetshenziswayo.
Izakhiwo:I-White Crystalline Powder. Incibilika emanzini kanye notshwala.Ukubeka: 1.651g / cm3, Iphuzu elincibilikayo: 73 ℃, iphuzu elibilayo: 200 ℃.
Isicelo:
1.I-phosphorous acidIsetshenziselwa ukukhiqiza usawoti we-phosphate njenge-potassium phosphite, i-ammonium phosphite ne-calcium phosfute. Kubandakanyeka ngenkuthalo lapho kulungiswa ama-phosphis afana ne-aminotris (methylephosphonic acid), 1-hydroxyethane 1,1-phophosbonic acid (hedp) kanye ne-2-phosphobutane-acid (PBTC), okutholayo Isicelo ekuthini ukwelashwa kwamanzi njengesilinganiso noma i-inhibitor esolisayo. Iphinde isetshenziswe ekuphendukeni kwamakhemikhali njenge-ejenti eyengeziwe. Usawoti wayo, i-phosfite yokuhola isetshenziswa njenge-PVC Stabilizer. Iphinde isetshenziswe njenge-preversor lapho kulungiswa i-phosphine futhi njengomphakathi lapho kulungiswa ezinye izinhlanganisela ze-phosphorus.
2.I-phosphorous acid(H3PO3, i-Orthophosphorous acid) ingahle isetshenziswe njengenye yezinto zokuphendula zokuhlanganiswa kokulandelayo:
I-α-aminomethylphosphos acid ngeMannich-Type MultiComponutent Reaction
I-1-amialalcnoneephosphonicid nge-amidoalkylation elandelwa yi-hydrolysis
Ama-Acid we-N-Ampinophonic avikelekile (ama-phospho-ama-ebsereses ama-amino acid wemvelo) nge-amidoalkylation reaction
3. Ukusetshenziswa Kwezimboni: Lo mqoqi wathuthukiswa muva nje futhi wasetshenziswa ngokuyinhloko njengomqokeleli othize we-cassiterite kusuka kububanzi be-cangphonic, i-albright noWilson basungule uhla lwabaqoqi ikakhulukazi ngokugcwala amamineralic ( ie cassiterite, ilmenite kanye ne-pyrocchlechlore). Kuncane kakhulu kwaziwa ngokusebenza kwalaba abaqoqi. Izifundo ezinqunyelwe ezenziwe ngeCassiteiterite ne-rutile ores zibonisa ukuthi abanye balaba baqoqi bakhiqiza i-tuloulinous froth kodwa bakhethe kakhulu.
Indlela yokukhiqiza:
Izindlela zokukhiqiza zezimboni zifaka i-Trichloroic phosphorus nosawoti we-phosphoric acid. Indlela ye-Hydrolysis kancane yengeza amanzi ekuphenduleni kwe-hydrolysis ngaphansi kokuxutshwa kwe-trichloride ukukhiqiza i-sub -phosphoric acid. Ngemuva kokucwengisisa, i-Cold ChemicalBook, i-crystallization kanye ne-discoloration kwenziwa, futhi umkhiqizo oqediwe wenziwa. I-PCI3 + 3H2O → H3PO3 + 3HCL ikhiqiza ukuphindaphindeka kwe-hydrogen chloride ngesikhathi sokukhiqiza, okungenziwa nge-hydrochloric acid.
Ezokuphepha:
Izici zobungozi ezivuthayo: Ku-H Hole Agent efinyelelekayo; Ukushisa kusula ubuthi obunobuthi be-phosphorus oxide fumes.
Izici zokugcina kanye nezinto zokuhamba: umoya omncane wokushisa umoya wokushisa owomile; Gcina ngokwahlukana no-ejenti we-H pore-ukukhulula kanye ne-Alkali.
Ukupakisha: 25kg / isikhwama
Isitoreji: Qhubeka nokuvimbela kahle, ukumelana nokukhanya futhi kuvikeleke kumswakama.
