Umkhiqizi Intengo Enhle I-Oxalic Acid CAS: 144-62-7

incazelo emfushane:

I-Oxalic acid iyi-dicarboxylic acid enamandla etholakala ezitshalweni eziningi nemifino, ngokuvamile njenge-calcium noma usawoti we-potassium.I-Oxalic acid iyona kuphela inhlanganisela engenzeka lapho amaqembu amabili e-carboxyl ehlanganiswa ngokuqondile;ngenxa yalesi sizathu i-oxalic acid ingenye ye-organic acid enamandla kakhulu.Ngokungafani namanye ama-carboxylic acid (ngaphandle kwe-formic acid), i-oxidized kalula;lokhu kwenza kube usizo njenge-ejenti yokunciphisa ukuthwebula izithombe, ukuhlanza, nokususwa kwe-inki.I-oxalic acid ivamise ukulungiselelwa ngokushisisa i-sodium formate ne-sodium hydroxide ukuze yakhe i-sodium oxalate, eguqulwa ibe yi-calcium oxalate futhi iphathwe nge-sulfuric acid ukuze kutholakale i-oxalic acid yamahhala.
Izinga le-oxalic acid liphansi kakhulu ezitshalweni eziningi nasekudleni okusekelwe ezitshalweni, kodwa kunesipinashi, i-chard kanye nemifino yebhitrudi ukuze iphazamise ukumuncwa kwe-calcium lezi zitshalo nazo.
Ikhiqizwa emzimbeni nge-metabolism ye-glyoxylic acid noma i-ascorbic acid.Ayifakwanga i-metabolized kodwa ikhishwa emchamweni.Isetshenziswa njenge-reagent yokuhlaziya kanye ne-ejenti yokunciphisa jikelele.I-Oxalic acid iyi-acaricide yemvelo esetshenziselwa ukwelapha izibungu ze-varroa emakoloni angenayo ama-brood, amaphakheji, noma izixuku.I-vaporized oxalic acid isetshenziswa abanye abafuyi bezinyosi njengesibulala-zinambuzane ngokumelene ne-Varroa mite eyisinambuzane.

Izakhiwo Zekhemikhali:I-Oxalic acid iyimpushana engenambala, engenaphunga, noma eqinile eyimbudumbudu.Ifomu elingenamanzi (COOH)2 liqinile elingenaphunga, elimhlophe;ikhambi liwuketshezi olungenambala.

Ukusetshenziswa kwe-Oxalic Acid

1. I-Oxalic acid ingasetshenziswa ngokuyinhloko njenge-ejenti yokunciphisa kanye ne-ejenti yokuhlanza, i-mordant yemboni yokudaya nokunyathelisa, futhi isetshenziselwa ukucwenga insimbi engavamile, ukuhlanganiswa kwe-oxalate ester amide ehlukahlukene, i-oxalate notshani, njll.

2. Isetshenziswa njenge-reagent yokuhlaziya.

3. Isetshenziswa njengama-reagents aselabhorethri, i-reagent yokuhlaziya i-chromatography, ama-intermediates odayi kanye nezinto ezijwayelekile.

4. I-Oxalic acid isetshenziselwa ikakhulukazi ukukhiqiza izidakamizwa ezinjengama-antibiotics kanye ne-borneol kanye ne-solvent yokukhipha insimbi engavamile, i-ejenti yokunciphisa nodayi, i-ejenti yokushuka, njll. Ngaphezu kwalokho, i-oxalic acid ingasetshenziselwa ukuhlanganiswa kwezinhlobo ezahlukene ze-oxalate. i-ester, i-oxalate, ne-oxamide ene-diethyl oxalate, i-sodium oxalate ne-calcium oxalate enesivuno esikhulu kakhulu.I-oxalate ingase isetshenziselwe ukukhiqizwa kwe-cobalt-molybdenum-alumina catalyst, ukuhlanza insimbi ne-marble kanye nokukhishwa kwezindwangu.

Ukusetshenziswa Kwezolimo:I-Oxalic acid, (COOH)2, ebizwa nangokuthi i-ethanedioic acid, iqinile emhlophe, eyicrystalline, inyibilika kancane emanzini.Kuyinhlanganisela yemvelo eyenziwe nge-oxidized kakhulu enomsebenzi obalulekile we-chelating.Ine-asidi eqinile futhi inobuthi, ekhiqizwa izitshalo eziningi ezifana ne-sorrel (i-sourwood), amaqabunga amaqabunga e-rhubarb, amagxolo e-eucalyptus nezimpande zezitshalo eziningi.Emangqamuzaneni ezitshalo nasezicutshini, i-oxalic acid inqwabelana njenge-sodium, potassium noma i-calcium oxalate, leyo yokugcina ivela njengamakristalu.Ngokulandelayo, usawoti we-oxalic acid ungena emizimbeni yezilwane nabantu, okubangela ukuphazamiseka kwe-pathological, kuye ngenani elisetshenzisiwe.Izinhlobo eziningi zesikhunta ezifana ne-Aspergillus, i-Penicillium, i-Mucor, kanye namanye ama-lichens kanye nesikhunta se-slime zikhiqiza amakristalu e-calcium oxalate.Ngemva kokufa kwalezi zinambuzane, izitshalo nezilwane, usawoti udedelwa emhlabathini, okubangela ubuthi obuthile.Kodwa-ke, amagciwane ehlisa i-oxalate, abizwa nge-Oxalobacter formigenes, anciphisa ukumuncwa kwe-oxalate ezilwaneni nakubantu.

I-Oxalic acid ingeyokuqala ochungechungeni lwama-dicarboxylic acid.Isetshenziswa (a) njenge-ejenti yokuhlanza amabala njengokugqwala noma uyinki, (b) ekukhiqizweni kwendwangu nesikhumba, futhi (c) njenge-monoglyceryl oxalate ekukhiqizweni kwe-ally1 utshwala ne-formic acid.
