inkcazo emfutshane:

I-oxalic acid yi-dicarboxylic acid enamandla efumaneka kwizityalo ezininzi kunye nemifuno, idla ngokuba yi-calcium okanye i-potassium salts yayo. I-oxalic acid yeyona nto inokwenzeka apho amaqela amabini e-carboxyl adityaniswe ngokuthe ngqo; ngenxa yesi sizathu i-oxalic acid yenye yezona asidi ze-organic zinamandla. Ngokungafaniyo nezinye ii-carboxylic acids (ngaphandle kwe-formic acid), i-oxidized ngokulula; oku kuyenza ibe luncedo njenge-arhente yokunciphisa imifanekiso, ukufiphaza, kunye nokususa i-inki. I-oxalic acid idla ngokulungiswa ngokufudumeza i-sodium formate nge-sodium hydroxide ukwenza i-sodium oxalate, eguqulwa ibe yi-calcium oxalate kwaye iphathwe nge-sulfuric acid ukuze ifumane i-oxalic acid yasimahla.
Amanqanaba e-oxalic acid aphantsi kakhulu kwizityalo ezininzi kunye nokutya okusekwe kwizityalo, kodwa kukho okwaneleyo kwispinatshi, i-chard kunye ne-beet greens ukuphazamisa ukufunxwa kwe-calcium equlethwe zezi zityalo.
Iveliswa emzimbeni ngokusetyenziswa kwe-glyoxylic acid okanye i-ascorbic acid. Ayisetyenziswa njenge-analytical reagent kunye ne-general reducing agent. I-Oxalic acid yi-acaricide yendalo esetyenziselwa unyango lwe-varroa mites kwiikholoni ezingenazo ii-brood, iipakethe, okanye ii-swarms. I-oxalic acid ephefumulayo isetyenziswa ngabanye abafuyi beenyosi njengesibulali-zinambuzane nxamnye ne-Varroa mite edlakadlaka.

Iipropati zeKhemikhali:I-oxalic acid yipowder engenambala, engenavumba, okanye i-granular solid. I-anhydrous form (COOH)2 yi-white solid engenavumba; isisombululo lulwelo olungenambala.

Ukusetyenziswa kwe-Oxalic Acid

1. I-oxalic acid ingasetyenziswa ikakhulu njengearhente yokunciphisa kunye nearhente yokumhlopheza, i-mordant yokutshintsha umbala kunye noshishino lokushicilela, ikwasetyenziswa ekucoceni isinyithi esinqabileyo, ukwenziwa kwe-oxalate ester amide eyahlukeneyo, i-oxalate kunye nengca, njl.

2. Isetyenziswa njenge-reagent yohlalutyo.

3. Isetyenziswa njengee-reagents zelebhu, i-reagent yohlalutyo lwe-chromatography, ii-intermediates zedayi kunye nezinto ezisemgangathweni.

4. I-oxalic acid isetyenziswa kakhulu ekuveliseni amayeza anjengee-antibiotics kunye ne-borneol kunye ne-solvent yokukhupha isinyithi esinqabileyo, i-reducing agent kunye nedayi, i-tanning agent, njl. Ukongeza, i-oxalic acid ingasetyenziselwa ukwenziwa kweentlobo ezahlukeneyo ze-oxalate ester, i-oxalate, kunye ne-oxamide kunye ne-diethyl oxalate, i-sodium oxalate kunye ne-calcium oxalate enesivuno esikhulu. I-oxalate ingasetyenziselwa ukuvelisa i-cobalt-molybdenum-alumina catalyst, ukucoca isinyithi kunye ne-marble kunye nokumhlophelisa impahla.

Ukusetyenziswa kwezolimo:I-Oxalic acid, (COOH)2, ekwabizwa ngokuba yi-ethanedioic acid, yinto emhlophe, eqinileyo, enyibilikayo kancinci emanzini. Yikhompawundi yendalo ene-oxidized eninzi enomsebenzi omkhulu we-chelating. Ine-asidi enamandla kwaye inetyhefu, iveliswa zizityalo ezininzi ezifana ne-sorrel (umuthi omuncu), amagqabi e-rhubarb, igxolo le-eucalyptus kunye neengcambu ezininzi zezityalo. Kwiiseli zezityalo kunye nezicubu, i-oxalic acid iqokelelwa njenge-sodium, i-potassium okanye i-calcium oxalate, apho le yokugqibela ivela njengeekristale. Kwelinye icala, iityuwa ze-oxalic acids zingena emizimbeni yezilwanyana kunye nabantu, zibangela iingxaki zesifo, kuxhomekeke kubungakanani obusetyenzisiweyo. Iintlobo ezininzi zefungi ezifana ne-Aspergillus, i-Penicillium, i-Mucor, kunye nezinye ii-lichens kunye ne-slime molds zivelisa iikristale ze-calcium oxalate. Xa ezi microorganisms zifa, izityalo kunye nezilwanyana, iityuwa ziyakhutshwa emhlabeni, zibangele ubuthi obuthile. Nangona kunjalo, ii-microbes ezitshabalalisa i-oxalate, ezibizwa ngokuba yi-Oxalobacter formigenes, zinciphisa ukufunxwa kwe-oxalate kwizilwanyana nakubantu.

I-oxalic acid yeyokuqala kuluhlu lwee-dicarboxylic acids. Isetyenziswa (a) njenge-bleaching agent kwii-stain ezifana ne-rust okanye i-inki, (b) kwimveliso yelaphu kunye nesikhumba, kunye (c) njenge-monoglyceryl oxalate kwimveliso ye-ally1 alcohol kunye ne-formic acid.
