I-Oxalic Acid

Incazelo emfushane:

Uhlobo lwe-organic acid, ngumkhiqizo we-metabolic wezinto eziphilayo, kanambambili acid, osatshalaliswa kabanzi ezitshalweni, ezilwaneni nasezintweni ezihlukile, futhi ezintweni ezihlukile eziphilayo zidlala imisebenzi ehlukene. Kutholakale ukuthi i-oxalic acid inothile ngezinhlobo zezitshalo ezingaphezu kwe-100, ikakhulukazi isipinashi, i-amaranth, isithombo sebhitrudi, i-purtlane, i-taro, amazambane amnandi neRhubarb. Ngoba i-oxalic acid inganciphisa i-bioavailability yezinto ezimbiwa phansi, kubhekwa njenge-anagod for ukumuncwa kanye nokusetshenziswa kwezinto zamaminerali. I-anydride yayo yi-carbon sesquoxide.

I-oxalic acid iyi-acid ebuthakathaka. I-onizant yokuqala ionizant njalo i-Constant Ka1 = 5.9 × 10-2 kanye ne-Iginant-Order Oninization Constant Ka2 = 6.4 × 10-5. Kunokujwayelekile kwe-acid. Kungakuvimba isisekelo, uhlukanise inkomba, bese udedela ikhabhoni diokside ngokuxhumana nama-carbonates. Inokuncishiswa okuqinile futhi kulula ukufakwa kwi-carbon dioxide namanzi nge-ejenti oxdizing. Isixazululo se-acid potassium permanganate (KMNO4) singadilizwa futhi sincishiswe ku-2-lea mosese ion.

Ukusetshenziswa Komkhiqizo

Isengezo Sokudaya

Embonini yokuphrinta nokudaya, ingafaka esikhundleni se-acetic acid ukwenza imibala eyinhloko. Isetshenziswa njengombala nombala we-bleach amadayi we-pigment. Ingahlanganiswa namakhemikhali athile ukuze athole amadayi, futhi angasetshenziswa njenge-stabilizer for dyse, ngaleyo ndlela anwebe impilo kadayi.

Umshini wokuhlwilisa

Ukusetshenziswa kwe-zeolite njengoba umFiller embonini yephepha kungathuthukisa ukusebenza nekhwalithi yephepha, ukuze ukuqina kwalo kwanda, kufakwe amanzi, kulula ukusikwa, futhi kungcono ukumelana nomlilo.

Umkhakha wePlastics

Umkhakha wePlastics wokukhiqizwa kwePolyvinyl Chloride, i-Amino Plastics, i-Urea Forkdehyde Plastics, ama-Chip ama-Peant nokunye.

Umkhakha we-Photovoltaic

I-oxalic acid nayo isetshenziswa embonini ye-Photovoltaic. I-oxalic acid ingasetshenziselwa ukwenza ama-silicon wafers amaphaneli elanga, asiza ekunciphiseni iziphambeko ebusweni be-silicon wafers.

Ukugeza isihlabathi

I-oxalic acid ihlangene ne-hydrochloric acid kanye ne-hydrofluoric acid kungenza nge-acid ukugeza isihlabathi se-quartz.

Synthesis Catalyst

Njengomkhathaza we-phenolic resin synthentis, ukusabela kwe-catalytic kuyinto ethambile, inqubo iqinile, futhi isikhathi yinde kunazo zonke. Isixazululo se-acetoone oxalate singakwazi ukusatshalaliswa ukusabela kokwelapha kwe-epoxy resin futhi sinciphise isikhathi sokwelapha. Iphinde isetshenziswe njengoMlawuli we-PH yokuhlanganiswa kwe-Urea-formaldehydede Resin ne-Melamine Formatdehyde Resin. Kungangezwa futhi ku-polyvinyl soluble aclusive anamathela ukuthuthukisa ijubane lokumisa namandla okubopha. Ingasetshenziswa futhi njenge-ejenti yelapha ye-urea-formaldehyde resin nensimbi ion chelating ejenti. Ingasetshenziswa njenge-accelerator ukulungiselela isitashi se-starch nge-KMNO4 oxidizing ejenti ukusheshisa isilinganiso se-oxidation futhi sifinyeze isikhathi sokuphendula.
