Indlela Yokuxuba Ama-carbohydrate e-Oxalic Acid
Le ndlela isebenzisa isitashi noshukela njengezinto zokusetshenziswa futhi iwaxube ne-nitric acid ku-73–80 °C ukukhiqiza i-oxalic acid. Uma sithatha isitashi njengesibonelo, inqubo imi kanje: Isitashi esingu-85% sobuningi sihlakazeka esixazululweni samanzi esiqukethe i-10% ye-oxalic acid noma uketshezi oluvela kumama lweminye imikhiqizo ephakathi, sishiswe nge-asidi, bese sibuyiselwa emuva amahora ayi-6 ukuze kutholakale kuqala i-glucose yomkhiqizo ophakathi. Ngemuva kwalokho, i-nitric acid kanye ne-iron-vanadium catalyst kungezwa ku-63 °C ukuze kuqhutshekwe ne-hydrolysis, bese i-oxalic acid itholakala ngokuhluzwa ngemva kokusabela.
Ukusabela okuyinhloko ukugeleza kwesitashi sibe yi-glucose, bese i-oxidized ibe yi-oxalic acid ene-nitric acid lapho kukhona khona
I-Fe 3+ kanye ne-V2O5V
ama-catalyst. Le ndlela ifaka izinto zokusetshenziswa ezitholakala kalula, inqubo elula, izimo zokusebenza ezithambile, kanye nokutshalwa kwezimali okuphansi, futhi amazwe angakhetha izinto zokusetshenziswa ezahlukene ngokwezimo zawo zemithombo. Ngokuphathelene nokukhiqiza kanye nezinzuzo zezomnotho, isitashi sommbila ngokuvamile siyisinqumo esingcono kakhulu. Kodwa-ke, ukungalungi kwayo kufaka phakathi isivuno esiphansi, ukusetshenziswa okukhulu kokusanhlamvu, izindleko zokukhiqiza eziphezulu, kanye nenani elikhulu lama-nitrogen oxides egesini yomsila, anobuthi obukhulu futhi abangela ukungcola okukhulu kwemvelo.

I-Shandong Pulisi Chemical ingumkhiqizi ochwepheshe waseShayina kanye nomhlinzeki we-oxalic acid (i-dihydrate, i-H₂C₂O₄·2H₂O) enokuhlanzeka okungenani okungu-99.6%.
