Indlela yokuOxidation yeCarbohydrate ye-Oxalic Acid
Le ndlela isebenzisa isitashi kunye neeswekile njengezinto eziluhlaza kwaye iyazixuba nge-nitric acid kwi-73–80 °C ukuvelisa i-oxalic acid. Umzekelo, le nkqubo yile: I-85% ye-mass fraction starch isasazeka kwisisombululo samanzi esine-10% ye-oxalic acid okanye utywala obungumama kwezinye iimveliso eziphakathi, ifudunyezwe nge-asidi, kwaye ihlanjululwe iiyure ezi-6 ukuze ifumane i-glucose yemveliso ephakathi. Emva koko, i-nitric acid kunye ne-iron-vanadium catalyst zongezwa kwi-63 °C ukuze kubekho i-hydrolysis engaphezulu, kwaye i-oxalic acid ifunyanwa ngokucocwa emva kwempendulo.
Eyona mpendulo iphambili kukuphakelwa kwesitatshi kwi-glucose, ethi emva koko i-oxidized ibe yi-oxalic acid kunye ne-nitric acid xa kukho
I-Fe 3+ kunye ne-V2O5V
ii-catalysts. Le ndlela inezixhobo ezifumaneka lula, inkqubo elula, iimeko zokusebenza ezithambileyo, kunye notyalo-mali oluphantsi, kwaye amazwe anokukhetha izixhobo ezahlukeneyo ngokweemeko zawo zemithombo. Ngokuphathelele isivuno kunye neenzuzo zoqoqosho, istatshi sombona ngokubanzi lolona khetho lubalaseleyo. Nangona kunjalo, iingxaki zayo ziquka isivuno esiphantsi, ukusetyenziswa kakhulu kweenkozo, iindleko eziphezulu zemveliso, kunye nesixa esikhulu se-nitrogen oxides kwigesi yomsila, ezinobungozi kakhulu kwaye zibangela ungcoliseko olukhulu lokusingqongileyo.

I-Shandong Pulisi Chemical ngumvelisi wobuchwephesha waseTshayina kunye nomthengisi we-oxalic acid (i-dihydrate, i-H₂C₂O₄·2H₂O) enobumsulwa obuphantsi obuyi-99.6%.
