Oxalic acid ke acid e fokolang.Taelo ea pele ea ionization kamehla Ka1 = 5.9 × 10-2 le ea bobeli ea ionization kamehla Ka2 = 6.4 × 10-5.E na le sebopeho sa acid.E ka fokotsa motheo, ea senya letšoao, 'me ea lokolla carbon dioxide ka ho sebelisana le carbonates.E na le reducibility e matla 'me e bonolo ho e kenya ka har'a carbon dioxide le metsi ka oxidizing agent.Tharollo ea asiti ea potassium permanganate (KMnO4) e ka ntšoa 'me ea fokotsoa ho 2-valence manganese ion.

Tšebeliso ea Sehlahisoa
Keketso ya ho daea
Indastering ea ho hatisa le ho daea, e ka nkela asiti ea acetic sebaka ho etsa mebala e ka sehloohong.E sebelisoa e le 'mala le bleach bakeng sa lidae tsa pigment.E ka kopanngoa le lik'hemik'hale tse itseng ho etsa li-dae, 'me e ka boela ea sebelisoa e le mokhoa oa ho tsitsisa lidae, kahoo e lelefatsa bophelo ba lidae.
Mohloeki
Tšebeliso ea zeolite e le ho tlatsa indasteri ea pampiri e ka ntlafatsa ts'ebetso le boleng ba pampiri, e le hore porosity ea eona e eketsehe, ho kenngoa ha metsi ho matlafatsoe, ho bonolo ho khaola, ho ngola tshebetso ho ntlafatsoa, 'me ho na le ho hanyetsa ho itseng ha mollo.
Indasteri ea polasetiki
Indasteri ea polasetiki bakeng sa tlhahiso ea polyvinyl chloride, polasetiki ea amino, polasetiki ea urea formaldehyde, likopi tsa pente joalo-joalo.
Indasteri ea Photovoltaic
Oxalic acid e boetse e sebelisoa indastering ea photovoltaic.Oxalic acid e ka sebelisoa ho etsa li-wafers tsa silicon bakeng sa liphanele tsa letsatsi, ho thusa ho fokotsa likoli holim'a liphaphatha tsa silicon.
Ho hlatsoa lehlabathe
Oxalic acid e kopantsoe le hydrochloric acid le hydrofluoric acid e ka sebetsa ho hlatsuoa ha acid ea lehlabathe la quartz.
Synthesis catalyst
E le sesosa sa phenolic resin synthesis, ts'ebetso ea catalytic ha e bonolo, ts'ebetso e batla e tsitsitse, 'me nako e telele ka ho fetisisa.Tharollo ea acetone oxalate e ka tsosa karabelo e folisang ea epoxy resin mme ea khutsufatsa nako ea ho folisa.E boetse e sebelisoa e le molaoli oa pH bakeng sa motsoako oa resin ea urea-formaldehyde le melamine formaldehyde resin.E ka boela ea eketsoa ho sekhomaretsi sa joala sa polyvinyl se qhibilihang ka metsi ho ntlafatsa lebelo la ho omisa le matla a tlamahano.E ka boela ea sebelisoa e le moemeli oa phekolo ea urea-formaldehyde resin le tšepe ea ion chelating agent.E ka sebelisoa e le accelerator ho lokisa starch binder ka KMnO4 oxidizing agent ho potlakisa sekhahla sa oxidation le ho khutsufatsa nako ea karabelo.
