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 zepigment. 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.
