Acide ya oxalic

Ibisobanuro bigufi:

Ni ubwoko bwa aside kama, nigicuruzwa cyibinyabuzima, aside iringaniye, ikwirakwizwa cyane mubihingwa, inyamaswa na fungi, kandi mubinyabuzima bitandukanye bigira imirimo itandukanye. Byagaragaye ko aside oxalic ikungahaye ku bwoko burenze 100 bwibimera, cyane cyane epinari, Amaranth, Beet, Taro, ibirayi byiza na Rhubarb. Kuberako aside oxalike irashobora kugabanya ibinyabuzima bigize amabuye y'agaciro, bifatwa nkumurwanya kugirango akure kandi akoreshe amabuye y'agaciro. Anhydride yayo ni karuboni esquioxide.

Acide ya oxalic ni aside ikomeye. Itegeko-rya mbere Ionisation Guhora Ka1 = 5.9 × 10-2 hamwe na kabiri iongation isanzwe ka2 = 6.4 × 10-5. Ifite aside. Irashobora gutesha agaciro ishingiro, ibuza icyerekezo, kandi urekure ubwana bwa karubone ukurikije imikoranire hamwe na karubone. Ifite imirongo ikomeye kandi biroroshye kugirirwa muri dioxyde ya karuboni n'amazi ukoresheje umukozi wa okiside. Potasiyumu ya Acide Permanganate (kmno4) irashobora kuboneka kandi ikagabanuka kuri 2-Valence Manganese ion.

Imikoreshereze y'ibicuruzwa

Irangi

Mugucapa no gusiga isoko, irashobora gusimbuza acide ya acetike kugirango ikore amabara yibanze. Ikoreshwa nkibibara no guhumeka kuri dyes. Irashobora guhuzwa nimiti imwe n'imwe kugirango ikore kuri dyes, kandi irashobora kandi gukoreshwa nkintangarugero kuri dyes, bityo tugatanga ubuzima bwa dyes.

Cleansser

Gusaba Zeolite nkuko byuzuzanya munganda birashobora kunoza imikorere nimpapuro, kugirango uburozi bwayo bwiyongera, ni bwo buryo bwo kwiyongera, biroroshye guca, kandi bifite imbaraga zo guhangana.

Inganda za plastics

Inganda za plastics kugirango umusaruro wa chloride ya polyviny, Amino plastiki, Urea formaldehyde plastiki, chip nziza nibindi.

Inganda za PhotoVoltaic

Acide ya Oxalic nayo ikoreshwa mu nganda za Photovoltaic. Acide ya oxalic irashobora gukoreshwa mugukora ibiranda bya silicon kubikorwa byizuba, bifasha kugabanya inenge hejuru ya wafer ya Silicon.

Gukaraba

Acide ya Oxalic yahujwe na aside hydrochloric na aside hydrofluoric irashobora gukora kuri aside ya quartz.

Synthesis catalyst

Nkumusemburo kuri synthesis ya perinolicasi, retalytic reaction yoroheje, inzira irahagaze neza, kandi igihe kirageze. Igisubizo cya acetone Irakoreshwa kandi nka ph redulator ya synthesis ya Urea-formaldehyde resin na melamine formaldehyde resin. Irashobora kandi kongerwaho amazi menshi polyvinyl inzoga zifatika zo kunoza umuvuduko wumisha hamwe nihungabana. Irashobora kandi gukoreshwa nka agent ya Urea-formaldehyde resin na byuma gion chelating agent. Irashobora gukoreshwa nkumuvuduko wo gutegura ibinyamisogwe hamwe numukozi wa KMNO4 yo kwihuta kwihutisha igipimo cya okiside hamwe nigihe gito.
