Oxalic acid ke ntho ea tlhaho e nang le foromo ea lik'hemik'hale H₂C₂O₄.Ke metabolite ea lintho tse phelang.Ke acid e fokolang ea dibasic.E ajoa haholo limeleng, liphoofolong le li-fungus, 'me e bapala mesebetsi e fapaneng linthong tse fapaneng.Asiti ea eona ea anhydride ke carbon trioxide.Ponahalo ea oxalic acid ke flake e se nang mebala ea monoclinic kapa kristale ea prismatic kapa phofo e tšoeu, tatso e bolila, e qhibilihang habonolo metsing empa e sa qhibilihe ka har'a lihlapolli tse kang ether.Boima ba molek'hule ea oxalic acid ke 90.0349.
Tšebeliso ea oxalic acid: motsoako o kopanyang, masking agent, precipitating agent, ho fokotsa.
1, joalo ka moemeli oa bleaching
Oxalic acid e sebelisoa haholo-holo e le moemeli oa ho fokotsa le ho soeufatsa, e sebelisoang tlhahiso ea lithethefatsi tse kang lithibela-mafu le borneol, e le solvent bakeng sa ho ntšoa ha litšepe tse sa tloaelehang, e le moemeli oa ho fokotsa dae, hape e le moemeli oa ho qhibiliha.
Oxalic acid e boetse e sebelisoa ho hlahisa cobalt-molybdenum-aluminium catalysts, ho hloekisa litšepe le 'mabole, le ho soeufala ha masela.
2. Joaloka moemeli ea fokotsang
Ka indasteri ea organic synthesis, e sebelisoa haholo ho hlahisa lihlahisoa tsa lik'hemik'hale tse kang hydroquinone, pentaerythritol, cobalt oxalate, nickel oxalate, le gallic acid.
Indasteri ea polasetiki e sebelisoa ho hlahisa polyvinyl chloride, aminoplastics, urea-formaldehyde plastics, lacquer sheets, joalo-joalo.
Indasteri ea dae e sebelisoa ho etsa botala ba magenta bo entsoeng ka letsoai, joalo-joalo.
Indastering ea khatiso le ho daea, e ka nkela asiti ea acetic sebaka ’me ea sebelisoa e le ntho e thusang ho hlahisa mebala le ho soeufatsa lidae tsa mebala.
Indasteri ea meriana e sebelisoa ha ho etsoa chlortetracycline, oxytetracycline, tetracycline, streptomycin, le ephedrine.
Ho feta moo, oxalic acid e ka boela ea sebelisoa ho kopanya lihlahisoa tse fapaneng tse kang oxalate, oxalate le oxalamide, tseo har'a tsona diethyl oxalate, sodium oxalate le calcium oxalate li hlahisang haholo.
3. Joaloka mordant
Antimony oxalate e ka sebelisoa e le mordant, 'me ferric ammonium oxalate ke moemeli oa ho hatisa lipolane.
4 Ts'ebetso ea ho tlosa mafome
Oxalic acid e ka sebelisoa ho tlosa mafome: reka botlolo ea oxalic acid ho tloha lebenkeleng le rekisang lik'hemik'hale tsa lik'hemik'hale, nka tse ling, etsa tharollo ka metsi a futhumetseng, e sebelise ho letheba la mafome 'me ue hlakole.(Tlhokomeliso: Ela hloko ha u sebelisa, oxalic acid e senya haholo ho tšepe e sa hloekang. Oxalic acid e nang le mahloriso a mangata e boetse e bonolo ho senya matsoho. 'Me oxalate ea acid e hlahisoang e qhibiliha haholo, empa e na le chefo e itseng. U se ke ua e ja. ha o sebelisa . Kamora hore letlalo le kopane le oxalic acid, le lokela ho hlatsuoa ka metsi ka nako.)
Ho boloka oxalic acid
1. Boloka sebakeng se omileng le se phodileng.Ha e le hantle e thibela mongobo, e thibela metsi, e sireletsa letsatsi.Mocheso oa mocheso ha oa lokela ho feta 40 ℃.
2. Boloka hole le li-oxide le lintho tsa alkaline.E phuthetsoe ka mokotleng o entsoeng ka polypropylene o kentsoeng ka mokotla oa polasetiki.
