Oxalic acid ndi dicarboxylic acid yamphamvu yomwe imapezeka mu zomera ndi ndiwo zamasamba zambiri, nthawi zambiri imakhala mchere wake wa calcium kapena potaziyamu. Oxalic acid ndiye chinthu chokhacho chomwe magulu awiri a carboxyl amalumikizidwa mwachindunji; pachifukwa ichi oxalic acid ndi imodzi mwa ma organic acid amphamvu kwambiri. Mosiyana ndi ma carboxylic acid ena (kupatula formic acid), imasungunuka mosavuta; izi zimapangitsa kuti ikhale yothandiza ngati chochepetsera kujambula zithunzi, kuyera, komanso kuchotsa inki. Oxalic acid nthawi zambiri imakonzedwa potenthetsa sodium formate ndi sodium hydroxide kuti ipange sodium oxalate, yomwe imasinthidwa kukhala calcium oxalate ndikuchiritsidwa ndi sulfuric acid kuti ipeze oxalic acid yaulere.
Kuchuluka kwa oxalic acid m'zakudya zambiri ndi zomera n'kochepa, koma mu sipinachi, chard ndi beet greens muli zokwanira kuti calcium isalowe m'thupi zomwe zomerazi zili nazo.
Imapangidwa m'thupi kudzera mu kagayidwe ka glyoxylic acid kapena ascorbic acid. Siigayidwa koma imatulutsidwa mu mkodzo. Imagwiritsidwa ntchito ngati chothandizira kusanthula komanso chochepetsera. Oxalic acid ndi acaricide yachilengedwe yomwe imagwiritsidwa ntchito pochiza nthata za varroa m'magulu omwe alibe ana, mapaketi, kapena magulu. Oxalic acid yotenthedwa ndi nthunzi imagwiritsidwa ntchito ndi alimi ena a njuchi ngati mankhwala ophera tizilombo toyambitsa matenda a Varroa mite.

Katundu wa Mankhwala:Oxalic acid ndi ufa wopanda mtundu, wopanda fungo, kapena granular solid. Anhydrous form (COOH)2 ndi cholimba choyera chopanda fungo; yankho ndi madzi opanda mtundu.

Kugwiritsa Ntchito Oxalic Acid

1. Oxalic acid ingagwiritsidwe ntchito makamaka ngati chochepetsera komanso choyeretsera, chopaka utoto ndi makampani osindikizira, komanso imagwiritsidwa ntchito poyeretsa zitsulo zosowa, kupanga mitundu yosiyanasiyana ya oxalate ester amide, oxalate ndi udzu, ndi zina zotero.

2. Amagwiritsidwa ntchito ngati chothandizira kusanthula.

3. Amagwiritsidwa ntchito ngati ma reagents a labotale, reagent yowunikira chromatography, ma intermediates a utoto ndi zinthu zokhazikika.

4. Oxalic acid imagwiritsidwa ntchito makamaka popanga mankhwala monga maantibayotiki ndi borneol ndi solvent potulutsa zitsulo zosowa, chochepetsera ndi utoto, chotenthetsera khungu, ndi zina zotero. Kuphatikiza apo, oxalic acid ingagwiritsidwenso ntchito popanga mitundu yosiyanasiyana ya oxalate ester, oxalate, ndi oxamide yokhala ndi diethyl oxalate, sodium oxalate ndi calcium oxalate zomwe zimakhala ndi phindu lalikulu. Oxalate ingagwiritsidwenso ntchito popanga cobalt-molybdenum-alumina catalyst, kuyeretsa chitsulo ndi marble komanso kuyeretsa nsalu.

Ntchito Zaulimi:Oxalic acid, (COOH)2, yomwe imatchedwanso ethanedioic acid, ndi yoyera, yolimba, yosungunuka pang'ono m'madzi. Ndi chinthu chachilengedwe chomwe chimasungunuka kwambiri chomwe chimagwira ntchito kwambiri pochotsa poizoni. Ndi acidic kwambiri komanso chakupha, chomwe chimapangidwa ndi zomera zambiri monga sorelo (sourwood), masamba a rhubarb, makungwa a eucalyptus ndi mizu yambiri ya zomera. M'maselo ndi minofu ya zomera, oxalic acid imasonkhanitsidwa ngati sodium, potaziyamu kapena calcium oxalate, yomwe yachiwiri imapezeka ngati makhiristo. Kenako, mchere wa oxalic acid umalowa m'matupi a nyama ndi anthu, zomwe zimayambitsa matenda, kutengera kuchuluka kwa chakudya. Mitundu yambiri ya bowa monga Aspergillus, Penicillium, Mucor, komanso lichens ndi slime molds zimapanga makhiristo a calcium oxalate. Tizilombo toyambitsa matenda, zomera ndi nyama zikafa, mcherewo umatulutsidwa m'nthaka, zomwe zimayambitsa poizoni pang'ono. Komabe, tizilombo toyambitsa matenda tomwe timawononga oxalate, totchedwa Oxalobacter formigenes, timachepetsa kuyamwa kwa oxalate mwa nyama ndi anthu.

Oxalic acid ndi yoyamba mwa mndandanda wa ma dicarboxylic acid. Imagwiritsidwa ntchito (a) ngati choyeretsera mabala monga dzimbiri kapena inki, (b) popanga nsalu ndi chikopa, ndipo (c) ngati monoglyceryl oxalate popanga ally1 alcohol ndi formic acid.
