Oxalic acid ndi chinthu chachilengedwe chokhala ndi formula yamankhwala H₂C₂O₄.Ndi metabolite ya zamoyo.Ndi dibasic ofooka asidi.Imagawidwa kwambiri muzomera, nyama ndi mafangasi, ndipo imagwira ntchito zosiyanasiyana m'zamoyo zosiyanasiyana.Asidi ake anhydride ndi carbon trioxide.Maonekedwe a oxalic acid ndi flake wopanda colorless monoclinic kapena prismatic crystal kapena ufa woyera, wopanda fungo, kukoma kowawasa, kusungunuka mosavuta m'madzi koma osasungunuka mu zosungunulira organic monga ether.Kulemera kwa molekyulu ya oxalic acid ndi 90.0349.
Kugwiritsa ntchito oxalic acid: complexing agent, masking agent, precipitating agent, reduction agent.
1, ngati wothandizira bleaching
Oxalic asidi makamaka ntchito ngati kuchepetsa wothandizila ndi Bleaching wothandizila, ntchito kupanga mankhwala monga maantibayotiki ndi borneol, monga zosungunulira kwa m'zigawo za zitsulo osowa, monga kuchepetsa wothandizila utoto, ndi monga wothandizila pofufuta.
Oxalic acid amagwiritsidwanso ntchito popanga cobalt-molybdenum-aluminium catalysts, kuyeretsa zitsulo ndi nsangalabwi, komanso kuyeretsa nsalu.
2. Monga chochepetsera
M'makampani opanga ma organic synthesis, amagwiritsidwa ntchito makamaka popanga mankhwala monga hydroquinone, pentaerythritol, cobalt oxalate, nickel oxalate, ndi gallic acid.
Makampani apulasitiki amagwiritsidwa ntchito popanga polyvinyl chloride, aminoplastics, mapulasitiki a urea-formaldehyde, mapepala a lacquer, ndi zina zotero.
Makampani opanga utoto amagwiritsidwa ntchito popanga mchere wa magenta wobiriwira, etc.
M'makampani osindikizira ndi opaka utoto, amatha kulowa m'malo mwa acetic acid ndikugwiritsidwa ntchito ngati chothandizira kupanga utoto komanso kupanga utoto wopaka utoto wa pigment.
Makampani opanga mankhwala amagwiritsidwa ntchito popanga chlortetracycline, oxytetracycline, tetracycline, streptomycin, ndi ephedrine.
Kuphatikiza apo, oxalic acid amathanso kugwiritsidwa ntchito popanga zinthu zosiyanasiyana monga oxalate, oxalate ndi oxalamide, zomwe zimapindulitsa kwambiri diethyl oxalate, sodium oxalate ndi calcium oxalate.
3. Monga mordant
Antimony oxalate ingagwiritsidwe ntchito ngati mordant, ndipo ferric ammonium oxalate ndi wothandizira kusindikiza mapulani.
4 Ntchito yochotsa dzimbiri
Oxalic acid angagwiritsidwe ntchito kuchotsa dzimbiri: gulani botolo la oxalic acid ku sitolo yomwe imagulitsa mankhwala opangira mankhwala, tengani, pangani yankho ndi madzi ofunda, ikani pa dzimbiri ndikupukuta.(Dziwani: Samalani mukamagwiritsa ntchito, oxalic acid amawononga kwambiri chitsulo chosapanga dzimbiri. Oxalic acid yokhala ndi ndende yayikulu ndiyosavuta kuwononga manja. Ndipo acid oxalate yomwe imapangidwa imakhala yosungunuka kwambiri, koma imakhala ndi kawopsedwe kena kake. Musadye izo. mukamagwiritsa ntchito . Khungu likakumana ndi oxalic acid, liyenera kutsukidwa ndi madzi pakapita nthawi.)
Oxalic acid yosungirako
1. Sungani pamalo ouma ndi ozizira.Zosakwanira chinyezi, zosalowa madzi, zoteteza ku dzuwa.Kutentha kosungirako sikuyenera kupitirira 40 ℃.
2. Khalani kutali ndi ma oxides ndi zinthu zamchere.Ananyamula mu polypropylene thumba thumba ali ndi thumba pulasitiki.
