I-Oxalic Acid

incazelo emfushane:

Iwuhlobo lwe-asidi ephilayo, ingumkhiqizo we-metabolic wezinto eziphilayo, i-asidi kanambambili, esatshalaliswa kabanzi ezitshalweni, ezilwaneni nasezikhunjini, futhi ezintweni eziphilayo ezihlukene zidlala imisebenzi eyahlukene.Kutholwe ukuthi i-oxalic acid inothile ngezinhlobo zezitshalo ezingaphezu kwekhulu, ikakhulukazi isipinashi, i-amaranth, ibhitrudi, i-purslane, i-taro, ubhatata kanye ne-rhubarb.Ngenxa yokuthi i-oxalic acid inganciphisa i-bioavailability yezakhi zamaminerali, ithathwa njengephikisana nokumuncwa kanye nokusetshenziswa kwezakhi zamaminerali.I-anhydride yayo i-carbon sesquioxide.

I-Oxalic acid iyi-asidi ebuthakathaka.I-ionization ye-oda lokuqala engaguquki Ka1=5.9×10-2 kanye ne-ionization ye-oda lesibili njalo Ka2=6.4×10-5.Ine-asidi evamile.Inganciphisa isisekelo, ishintshe umbala inkomba, futhi ikhulule i-carbon dioxide ngokusebenzisana nama-carbonates.Ine-reducibility eqinile futhi kulula ukuthi ifakwe kwi-carbon dioxide nasemanzini nge-oxidizing agent.Isixazululo se-Acid potassium permanganate (KMnO4) singashintsha umbala futhi sehliselwe ku-2-valence manganese ion.

Ukusetshenziswa komkhiqizo

Isengezo sokudaya

Embonini yokunyathelisa nokudaya, ingathatha indawo ye-acetic ukuze yenze imibala eyinhloko.Isetshenziswa njenge-colorant kanye ne-bleach kumadayi we-pigment.Ingahlanganiswa namakhemikhali athile ukwenza odayi, futhi ingasetshenziswa njengesiqinisi samadayi, ngaleyo ndlela yandise ukuphila kwamadayi.

Isihlanzi

Ukusetshenziswa kwe-zeolite njengokugcwalisa embonini yamaphepha kungathuthukisa ukusebenza kanye nekhwalithi yephepha, ukuze i-porosity yayo ikhule, ukumuncwa kwamanzi kuthuthukisiwe, kulula ukusika, ukusebenza kokubhala kuthuthukiswa, futhi kunokumelana okuthile nomlilo.

Imboni yepulasitiki

Imboni yepulasitiki yokukhiqiza i-polyvinyl chloride, amapulasitiki amino, amapulasitiki e-urea formaldehyde, ama-chips opende nokunye.

Imboni ye-Photovoltaic

I-Oxalic acid nayo isetshenziswa embonini ye-photovoltaic.I-Oxalic acid ingasetshenziswa ukwenza ama-wafer e-silicon amaphaneli elanga, okusiza ukunciphisa amaphutha ebusweni bama-silicon wafers.

Ukugeza isihlabathi

I-Oxalic acid ehlanganiswe ne-hydrochloric acid kanye ne-hydrofluoric acid ingasebenza ekugezeni kwe-asidi yesihlabathi se-quartz.

I-synthesis catalyst

Njenge-catalyst ye-phenolic resin synthesis, ukusabela kwe-catalytic kuthambile, inqubo izinzile uma kuqhathaniswa, futhi ubude besikhathi bude kakhulu.Isixazululo se-acetone oxalate singadala ukusabela okwelaphayo kwe-epoxy resin futhi sinciphise isikhathi sokuphulukisa.Ibuye isetshenziswe njengesilawuli se-pH sokuhlanganiswa kwe-urea-formaldehyde resin ne-melamine formaldehyde resin.Ingase futhi yengezwe ku-adhesive ye-polyvinyl alcohol encibilika emanzini ukuze kuthuthukiswe isivinini sokumisa namandla okubopha.Ingasetshenziswa futhi njenge-ejenti yokwelapha ye-urea-formaldehyde resin kanye ne-metal ion chelating ejenti.Ingasetshenziswa njengesisheshisi ukulungisa i-starch binder ene-oxidizing ye-KMnO4 ukusheshisa izinga le-oxidation kanye nokunciphisa isikhathi sokusabela.
