Umenzi Ixabiso Elilungileyo I-Oxalic Acid CAS: 144-62-7

inkcazelo emfutshane:

I-Oxalic acid yi-dicarboxylic acid eyomeleleyo eyenzeka kwizityalo ezininzi kunye nemifuno, njenge-calcium okanye iityuwa ze-potassium.I-Oxalic acid kuphela kwekhompawundi enokwenzeka apho amaqela amabini e-carboxyl adityaniswa ngokuthe ngqo;ngenxa yesi sizathu i-asidi ye-oxalic yenye yezona acids ezinamandla eziphilayo.Ngokungafaniyo nezinye i-carboxylic acids (ngaphandle kwe-formic acid), i-oxidized ngokulula;oku kwenza ukuba kube luncedo njenge-arhente yokunciphisa ukufota, ukuxutywa kwe-bleaching, kunye nokususwa kwe-inki.I-asidi ye-Oxalic idla ngokulungiswa ngokufudumeza ifomathi yesodium kunye ne-sodium hydroxide ukwenza i-sodium oxalate, eguqulwa ibe yi-calcium oxalate kwaye iphathwe nge-asidi ye-sulfuric ukufumana i-oxalic acid yamahhala.
Uxinzelelo lwe-oxalic acid lusezantsi kakhulu kwizityalo ezininzi kunye nokutya okusekelwe kwizityalo, kodwa kukho okwaneleyo kwisipinatshi, i-chard kunye ne-beet eluhlaza ukuphazamisa ukufunxwa kwe-calcium ezi zityalo ziqulethe.
Iveliswa emzimbeni nge-metabolism ye-glyoxylic acid okanye i-ascorbic acid.Ayinametabolized kodwa ikhutshwa kumchamo.Isetyenziswa njenge-reagent yokuhlalutya kunye ne-agent yokunciphisa ngokubanzi.I-asidi ye-Oxalic yi-acaricide yendalo esetyenziselwa unyango oluchasene ne-varroa mites kwiikoloni kunye ne-no / low brood, iipakethi, okanye i-swarms.Umphunga oxalic acid usetyenziswa ngabanye abafuyi beenyosi njengesibulali zinambuzane kwi Varroa mite.

Iinkcazelo ngeMichiza:Iasidi ye-Oxalic ngumgubo ongenambala, ongenavumba, okanye oqinileyo wegranular.I-anhydrous form (COOH)2 yinto engenavumba, emhlophe eqinileyo;isisombululo lulwelo olungenambala.

Ukusetyenziswa kwe-Oxalic Acid

1. I-asidi ye-oxalic ingasetyenziselwa ubukhulu becala njenge-arhente yokunciphisa kunye ne-ejenti ye-bleaching, i-mordant yokudaya kunye noshishino lokushicilela, isetyenziselwa ukucokisa isinyithi esinqabileyo, ukuhlanganiswa kwe-oxalate ester amide eyahlukeneyo, i-oxalate kunye nengca, njl.

2. Isetyenziswe njenge-reagent yohlalutyo.

3. Isetyenziswe njengeejenti zebhubhoratri, i-reagent yohlalutyo lwe-chromatography, i-dayi ephakathi kunye nezinto eziqhelekileyo.

4. Oxalic acid ikakhulu isetyenziselwa ukuvelisa amachiza ezifana antibiotics kunye borneol kunye nenyibilikisi yokuhluza metal ezinqabileyo, arhente ukunciphisa kunye nedayi, arhente ukushuka, njl. Ukongeza, acid oxalic ingasetyenziselwa ukudibanisa iintlobo ezahlukeneyo oxalate. I-ester, i-oxalate, kunye ne-oxamide ene-diethyl oxalate, i-sodium oxalate kunye ne-calcium oxalate enesivuno esikhulu.I-oxalate ingasetyenziselwa ukuveliswa kwe-cobalt-molybdenum-alumina catalyst, ukucocwa kwesinyithi kunye ne-marble kunye nokuxutywa kwe-bleaching of textiles.

Usetyenziso lwezoLimo:I-Oxalic acid, (COOH)2, ikwabizwa ngokuba yi-ethanedioic acid, imhlophe, icrystalline eqinileyo, enyibilikayo kancinane emanzini.Yinto eyenzeka ngokwemvelo ene-oxidized organic ikhompawundi kunye nomsebenzi obalulekileyo we-chelating.I-acidic kakhulu kwaye inetyhefu, iveliswa zizityalo ezininzi ezifana ne-sorrel (sourwood), amagqabi amagqabi e-rhubarb, ixolo le-eucalyptus kunye neengcambu ezininzi zezityalo.Kwiiseli zesityalo kunye nezicubu, i-oxalic acid iqokelelwa njenge-sodium, i-potassium okanye i-calcium oxalate, apho i-oxalic iyenzeka njengeekristale.Emva koko, iityuwa ze-oxalic acids zingena emizimbeni yezilwanyana kunye nabantu, ezibangela ukuphazamiseka kwe-pathological, kuxhomekeke kwisixa esisetyenzisiweyo.Iindidi ezininzi zomngundo ezifana neAspergillus, Penicillium, Mucor, kunye nezinye iilichens kunye nokungunda kweslime zivelisa iikristale zecalcium oxalate.Emva kokufa kwezi microorganisms, izityalo kunye nezilwanyana, ityuwa iphuma emhlabeni, ibangela umlinganiselo othile wetyhefu.Nangona kunjalo, iintsholongwane ze-oxalate-degrading microbes, ezibizwa ngokuba yi-Oxalobacter formigenes, zinciphisa ukufunxwa kwe-oxalate kwizilwanyana nakubantu.

I-Oxalic acid yeyokuqala kuthotho lwee-dicarboxylic acids.Isetyenziswa (a) njenge-ejenti ye-bleaching yamabala afana ne-rust okanye i-inki, (b) kwimveliso ye-textile kunye ne-leather, kunye (c) njenge-monoglyceryl oxalate ekuveliseni i-alcohol ye-ally1 kunye ne-fomic acid.
