Oxalic acid ndi amphamvu dicarboxylic acid omwe amapezeka muzomera ndi ndiwo zamasamba zambiri, nthawi zambiri monga mchere wa calcium kapena potaziyamu.Oxalic acid ndi gawo lokhalo lomwe lingatheke pomwe magulu awiri a carboxyl amalumikizana mwachindunji;pachifukwa ichi asidi oxalic ndi mmodzi wa zidulo amphamvu organic.Mosiyana ndi ma carboxylic acids (kupatula formic acid), imapangidwa ndi okosijeni mosavuta;izi zimapangitsa kuti zikhale zothandiza ngati chochepetsera kujambula, kupukuta, ndi kuchotsa inki.Oxalic acid nthawi zambiri amakonzedwa ndi kutentha kwa sodium formate ndi sodium hydroxide kupanga sodium oxalate, yomwe imasandulika kukhala calcium oxalate ndikuthandizidwa ndi sulfuric acid kuti ipeze oxalic acid yaulere.
Kuchuluka kwa oxalic acid m'zomera ndi zakudya zochokera ku zomera zambiri kumakhala kochepa kwambiri, koma sipinachi, chard ndi masamba a beet ndi okwanira kuti asokoneze kuyamwa kwa calcium yomwe zomerazi zili nazo.
Amapangidwa m'thupi ndi metabolism ya glyoxylic acid kapena ascorbic acid.Si zimapukusidwa koma excreted mu mkodzo.Amagwiritsidwa ntchito ngati reagent yowunikira komanso kuchepetsa agent.Oxalic acid ndi acaricide yachilengedwe yomwe imagwiritsidwa ntchito pochiza nthata za varroa m'magulu opanda ana / otsika, mapaketi, kapena dzombe.Vaporized oxalic acid amagwiritsidwa ntchito ndi alimi ena ngati mankhwala ophera tizilombo toyambitsa matenda a Varroa mite.

Chemical Properties:Oxalic acid ndi ufa wopanda mtundu, wopanda fungo, kapena wokhazikika wagranular.Mawonekedwe a anhydrous (COOH)2 ndi osanunkhiza, oyera olimba;yankho lake ndi madzi opanda mtundu.

Kugwiritsa ntchito Oxalic Acid

1. Oxalic acid angagwiritsidwe ntchito makamaka ngati kuchepetsa wothandizila ndi blekning wothandizila, mordant kwa utoto ndi makampani kusindikiza, komanso ntchito kuyenga osowa zitsulo, kaphatikizidwe osiyanasiyana oxalate ester amide, oxalate ndi udzu, etc.

2. Ntchito ngati analytical reagent.

3. Ntchito ngati reagents labotale, chromatography kusanthula reagent, intermediates utoto ndi zinthu muyezo.

4. Oxalic acid zimagwiritsa ntchito popanga mankhwala monga mankhwala ndi borneol ndi zosungunulira kwa yopezera osowa zitsulo, kuchepetsa wothandizila ndi utoto, pofufuta wothandizila, etc. Komanso, asidi oxalic Angagwiritsidwenso ntchito kwa synthesis mitundu yosiyanasiyana ya oxalate. ester, oxalate, ndi oxamide okhala ndi diethyl oxalate, sodium oxalate ndi calcium oxalate okhala ndi zokolola zambiri.Oxalate itha kugwiritsidwanso ntchito popanga cobalt-molybdenum-alumina chothandizira, kuyeretsa zitsulo ndi nsangalabwi komanso kutsuka kwa nsalu.

Ntchito Zaulimi:Oxalic acid, (COOH)2, wotchedwanso ethanedioic acid, ndi woyera, crystalline olimba, sungunuka pang'ono m'madzi.Ndi chilengedwe chopangidwa mwachilengedwe chokhala ndi okosijeni kwambiri chomwe chimakhala ndi ntchito yayikulu ya chelating.Ndi kwambiri acidic ndi poyizoni, opangidwa ndi zomera zambiri monga sorelo (sourwood), masamba masamba a rhubarb, khungwa la bulugamu ndi ambiri zomera mizu.M'maselo a zomera ndi minyewa, oxalic acid amadziunjikira ngati sodium, potaziyamu kapena calcium oxalate, yomwe yomalizayo imakhala ngati makhiristo.Komanso, mchere wa oxalic zidulo kulowa matupi a nyama ndi anthu, kuchititsa matenda matenda, malinga ndi kuchuluka kwa kudya.Mitundu yambiri ya bowa monga Aspergillus, Penicillium, Mucor, komanso ndere ndi nkhungu za matope zimatulutsa timadzi ta calcium oxalate.Pa imfa ya tizilombo tating'onoting'ono, zomera ndi nyama, mchere amamasulidwa mu nthaka, kuchititsa kuchuluka kwa kawopsedwe.Komabe, tizilombo towononga oxalate, totchedwa Oxalobacter formigenes, timachepetsa kuyamwa kwa oxalate mu nyama ndi anthu.

Oxalic acid ndiye woyamba mwa mndandanda wa ma dicarboxylic acid.Amagwiritsidwa ntchito (a) ngati bleaching wothandizira madontho ngati dzimbiri kapena inki, (b) kupanga nsalu ndi zikopa, ndi (c) monga monoglyceryl oxalate popanga ally1 mowa ndi formic acid.
