I-Oxalic Acid

inkcazelo emfutshane:

Ngaba luhlobo lwe-asidi ephilayo, yimveliso ye-metabolic yezinto eziphilayo, i-asidi ye-binary, isasazwa ngokubanzi kwizityalo, izilwanyana kunye nefungi, kwaye kwizinto eziphilayo ezihlukeneyo zidlala imisebenzi eyahlukeneyo.Kufunyaniswe ukuba i-oxalic acid ityebile kwiindidi ezingaphezulu kwe-100 zezityalo, ngakumbi isipinatshi, i-amaranth, ibhiti, i-purslane, i-taro, ibhatata kunye ne-rhubarb.Ngenxa yokuba i-oxalic acid inokunciphisa i-bioavailability yezinto ezimbiwa phantsi, ithathwa njengomchasi wokufunxa kunye nokusetyenziswa kwezinto zamaminerali.I-anhydride yayo yi-carbon sesquioxide.

I-Oxalic acid yi-asidi ebuthathaka.Umyalelo wokuqala we-ionization rhoqo Ka1 = 5.9 × 10-2 kunye ne-ionization yomyalelo wesibini rhoqo Ka2 = 6.4 × 10-5.Ineasidi eqhelekileyo.Iyakwazi ukunciphisa isiseko, i-discolor isalathisi, kwaye ikhulule i-carbon dioxide ngokusebenzisana ne-carbonates.Inokunciphisa okunamandla kwaye kulula ukuba i-oxidized ibe yi-carbon dioxide kunye namanzi nge-agent e-oxidizing.Isisombululo se-Acid potassium permanganate (KMnO4) sinokuguqulwa sibe yi-2-valence manganese ion.

Ukusetyenziswa kweMveliso

Isongezo sokudaya

Kwishishini lokushicilela nelokudaya, inokuthatha indawo yeacetic acid ukwenza imibala ephambili.Isetyenziswa njengombala kunye neblitshi kwiidayi ze-pigment.Inokudibaniswa kunye neekhemikhali ezithile ukwenza idayi, kwaye ingasetyenziselwa ukuzinzisa idayi, ngaloo ndlela yandisa ubomi bedayi.

Isicoci

Ukusetyenziswa kwe-zeolite njenge-filler kwishishini lephepha kunokuphucula ukusebenza kunye nomgangatho wephepha, ukwenzela ukuba i-porosity yayo inyuke, ukuxutywa kwamanzi kuphuculwe, kulula ukusika, ukusebenza kokubhala kuphuculwe, kwaye kunokumelana nomlilo othile.

Ishishini leplastiki

Imboni yeplastiki yokuvelisa i-polyvinyl chloride, iiplastiki ze-amino, iiplastiki ze-urea ze-formaldehyde, iitshiphu zepeyinti njalo njalo.

Ushishino lwefotovoltaic

I-Oxalic acid iphinda isetyenziswe kwishishini le-photovoltaic.Iasidi ye-oxalic ingasetyenziselwa ukwenza ii-silicone wafers kwiipaneli zelanga, inceda ukunciphisa iziphene kumphezulu we-silicon wafers.

Ukuhlamba isanti

I-asidi ye-oxalic edityaniswe ne-hydrochloric acid kunye ne-hydrofluoric acid inokusebenza kwi-asidi yokuhlamba isanti ye-quartz.

I-Synthesis catalyst

Njenge-catalyst ye-phenolic resin synthesis, i-catalytic reaction ithambile, inkqubo izinzile, kwaye ubude bexesha elide kakhulu.Isisombululo se-acetone oxalate sinokubangela ukusabela kokunyanga kwe-epoxy resin kunye nokunciphisa ixesha lokunyanga.Ikwasetyenziswa njengolawulo lwe-pH yokwenziwa kweresin ye-urea-formaldehyde kunye ne-melamine formaldehyde resin.Isenokongezwa kwi-adhesive ye-polyvinyl alcohol enyibilikayo emanzini ukuphucula isantya sokumisa kunye namandla okudibanisa.Isenokusetyenziswa njenge-ejenti yokunyanga ye-urea-formaldehyde resin kunye ne-metal ion chelating agent.Ingasetyenziswa njenge accelerator ukulungiselela isitatshi binder nge KMnO4 arhente oxidizing ukukhawulezisa izinga oxidation kunye nokunciphisa ixesha reaction.
