Aside ya Oxalic ni aside ikomeye ya dicarboxylike iboneka mu bimera byinshi n'imboga, akenshi ikaba ari umunyu wayo wa kalisiyumu cyangwa potasiyumu. Aside ya Oxalic ni yo yonyine ishoboka aho amatsinda abiri ya karboxylike ahurizwa hamwe; kubera iyo mpamvu aside ya Oxalic ni imwe muri aside organic zikomeye cyane. Bitandukanye n'izindi aside za karboxylike (usibye aside formike), ihita ihinduka oxidized; ibi bituma iba ingirakamaro mu gufotora, gusiba, no gukuraho wino. Aside ya Oxalic ikunze gutegurwa hakoreshejwe gushyushya sodium formate na sodium hydroxide kugira ngo habeho sodium oxalate, ihinduka sodium oxalate hanyuma igaterwa na aside sulfuric kugira ngo haboneke aside oxalic free.
Ingano ya aside oxalic iri hasi cyane mu bimera byinshi n'ibiribwa bikomoka ku bimera, ariko hari ihagije mu mboga za epinari, chard na beetroot kugira ngo bivange calcium mu kwinjiza ibi bimera.
Ikorerwa mu mubiri binyuze mu ihinduka rya aside glyoxylic cyangwa aside ascorbic. Ntabwo ihinduka ahubwo isohoka mu nkari. Ikoreshwa nk'ikintu gisesengura kandi kigatuma igabanuka. Aside oxalic ni umuti w’uburozi karemano ukoreshwa mu kuvura udukoko twa varroa mu matsinda y’udukoko tudafite/tudafite abana, udupaki, cyangwa amatsinda y’udukoko. Aside oxalic ivamo umwuka ikoreshwa na bamwe mu bavumvu nk'umuti wica udukoko twa Varroa duterwa n’udukoko.

Imiterere y'ibinyabutabire:Aside ya Oxalic ni ifu idafite ibara, idafite impumuro, cyangwa ikintu gikomeye kitagira ingano. Ifishi ya aside (COOH)2 ni ikintu cy’umweru kidafite impumuro; umuti ni amazi adafite ibara.

Imikoreshereze ya aside oxalic

1. Aside ya oxalic ishobora gukoreshwa cyane cyane nk'ikintu kigabanya ubushyuhe n'ikintu gihumanya ikirere, ikoreshwa mu gusiga amarangi no gucapa, inakoreshwa mu gutunganya ibyuma bidasanzwe, gukora oxalate ester amide zitandukanye, oxalate n'ibyatsi, nibindi.

2. Ikoreshwa nk'igikoresho cy'isesengura.

3. Bikoreshwa nk'ibikoresho byo muri laboratwari, ibikoresho byo gusesengura chromatography, ibikoresho byo gusiga irangi n'ibikoresho bisanzwe.

4. Aside ya oxalike ikoreshwa cyane cyane mu gukora imiti nka antibiyotike na borneol na solvent mu gukuramo icyuma kidasanzwe, igikoresho cyo kugabanya irangi n'irangi, igikoresho cyo gukaranga, nibindi. Byongeye kandi, aside ya oxalike ishobora kandi gukoreshwa mu gukora ubwoko butandukanye bwa oxalate ester, oxalate, na oxamide hamwe na diethyl oxalate, sodium oxalate na calcium oxalate bifite umusaruro mwinshi. Oxalate ishobora kandi gukoreshwa mu gukora catalyst ya cobalt-molybdenum-alumina, gusukura icyuma na marble ndetse no gusiga bleach ku myenda.

Imikoreshereze y'ubuhinzi:Aside ya Oxalic, (COOH)2, yitwa kandi aside ethanedioic, ni ikintu cy'umweru, gifite kristalo, gishongesha gato mu mazi. Ni ikintu gisanzwe gifite oxidized nyinshi kandi gifite imikorere ikomeye yo gusya. Ni aside nyinshi kandi ni uburozi, ikorwa n'ibimera byinshi nka sorrel (sourwood), amababi y'amababi ya rhubarb, igishishwa cya eucalyptus n'imizi myinshi y'ibimera. Mu turemangingo tw'ibimera n'uturemangingo, aside ya Oxalic yirundanya nk'umunyu, potasiyumu cyangwa calcium oxalate, muri byo iyi ya nyuma iboneka nk'uturemangingo. Hanyuma, umunyu wa aside ya Oxalic winjira mu mibiri y'inyamaswa n'abantu, bigatera indwara, bitewe n'ingano y'ibinyobwa. Amoko menshi y'ibihumyo nka Aspergillus, Penicillium, Mucor, ndetse na lichens na slime moulds bimwe na bimwe bitanga crystals ya calcium oxalate. Iyo izi mikorobe, ibimera n'inyamaswa bipfuye, umunyu urekurwa mu butaka, bigatera uburozi runaka. Ariko, mikorobe zangiza oxalate, zitwa Oxalobacter formigenes, zigabanya kwinjiza oxalate mu nyamaswa no mu bantu.

Aside ya oxalike ni yo ya mbere mu ruhererekane rwa aside dicarboxylic. Ikoreshwa (a) nk'umuti wo gusibanganya ibara nk'ingese cyangwa wino, (b) mu gukora imyenda n'uruhu, na (c) nka monoglyceryl oxalate mu gukora alcool na aside formic.
