Indlela ye-Oxidation ye-Glyoxal ye-Oxalic Acid
iGlyoxal inekunciphisa lokucinile, ngako ingasheshe ibe yi oxalic acid ngaphansi kwesento se nitric acid lecinile lekhicita i-oksijini. Ngenca yetintfo letifana nekuniketwa kwetintfo letiluhlata, intsengo, kanye nebuchwepheshe, lendlela inekuncintisana lokubi emakethe futsi ayikakhicitwa.
Ngetulu kwaloko, kunetinye tindlela tekwentiwa kwe-oxalic acid:
(1) Indlela yekulungisa i- carbon dioxide: I- carbon dioxide icale incishiswe ibe ngulesemkhatsini .
I-CO2
bese tiyaguculwa tibe nguletinye tintfo letiphilako. I-Oxalic acid itfolakala ngekutsi kukhishwe imisebe etinhlelo letehlukene te carbon dioxide ngetindlela temakhemikhali agezi kanye ne γ-rays, kukhanya kwelilanga, noma tibane te mercury letinemfutfo lomkhulu.
(2) Indlela yekuncibilikisa iAlkali kusetjentiswa tintfo leticebile nge cellulose: Kuhlanganiswa kwetintfo leticebile nge cellulose (njengetigodvo letilahliwe, ichaff, njll) kanye ne alkali lecinile lengakaphili iyancibilikiswa ngekuhlanganyela ku 513–558 K kwentela kukhicita ngetulu kwa 50% we oxalate. Emakristalu e-oxalate acindzetelwa ngekutsi abe ngemakristalu, bese kusetjentiswa i-sulfuric acid kutfola le-oxalic acid lephelile. Lendlela inendlela lelula yekulungisa i-oxalic acid, kepha lizinga lekugucuka kwe-single-pass liphansi (ngaphansi kwa 35%), kusetjentiswa kwe alkali kusetulu, futsi kungcola kwemvelo kukhulu kakhulu.
(3) Indlela yekukhicita tintfo letiluhlata temalahle: Ilungiselelwe kusuka kuma peats lahlukahlukene njengetintfo letiluhlata. Sibonelo, esidi ye oxalic ikhicitwa kusuka ku peat ye genera ye Sphagnum kanye ne Polytrichum ngekusebentisa i-oksidi ye nitric esidi. Lokuphendvula kwentiwa ku 343 K emahora langu 8-9, ngekukhicita lokufika ku 95%. Uma tintfo letiluhlata letifana netiti temalahle tisetjentiswa kukhicita i-oxalic acid, umkhicito nawo ufika ku 51%.
