Indlela Yekufaka I-Oxidation Ye-Oxalic Acid
Lendlela isebentisa sitashi kanye nashukela njengetintfo letiluhlata bese iyatifaka i-oxidize nge nitric acid ku 73–80 °C kwentela kukhicita i-oxalic acid. Kutsatsa sitashi njengesibonelo, lenchubo inje: 85% we mass fraction starch usakatwa ngesisombululo lesinemanti lesine 10% we oxalic acid noma tjwala lobuke baletinye tintfo letisemkhatsini, bushiswa nge esidi, bese buphindze buphindze bufakwe emahora lasitfupha kwentela kucala kutfola umkhicito losemkhatsini we glucose. Ngemuva kwaloko, i-nitric acid kanye ne-iron-vanadium lekhutsatako kungetwa ku 63 °C kwentela kuchubeka nekuhlanganiswa kwemanti, bese i-oxalic acid itfolakala ngekucolisa ngemuva kwekuphendvula.
Lokuphendvula lokuyinhloko kuhlanganiswa kwemanti kwesitashi sibe nguglucose, lese iyakhicitwa ibe yi-oxalic acid nge-nitric acid lapho kune
I-Fe 3+ kanye ne-V2O5V
tintfo letikhutsatako. Lendlela ifaka tintfo letiluhlata letitfolakala kalula, inchubo lelula, timo tekusebenta letincane, kanye nekutjala imali lokuphansi, futsi emave angakhetsa tintfo letiluhlata letehlukene ngekuya kwetimo tawo tetinsita. Ngekuya kwekukhicita kanye netinzuzo temnotfo, sitashi sembila sivame kuba ngulokukhetsa lokuhle kakhulu. Nomakunjalo, lokubi kwayo kufaka umkhicito lophansi, kudla lokuningi kwetinhlavu, tindleko letisetulu tekukhicita, kanye nelinani lelikhulu le nitrogen oxides kugesi wemsila, lokunebuthi kakhulu futsi kubangela kungcola lokukhulu kwemvelo.

I-Shandong Pulisi Chemical ngumkhiciti waseShayina loyingcweti futsi umphakeli we-oxalic esidi lesesigabeni setimboni lehlantekile kakhulu (i-dihydrate, i-H2C2O4·2H2O) lene-99.6% yekuhlanteka lokuncane.

Tindvwangu nekudaya: I-ejenti yekuhlanta umbala, lusito lwekulungisa umbala
Kucubungula sikhumba: Kushisa kanye nekususa umlotsa
Insimbi nekwelashwa kwemhlabatsi: Kususa umhlwa, kususa libala, kucwebetela emabhali
Metallurgy: I-ejenti yekukhicita insimbi lengakavami emhlabeni
Kuhlanganiswa kwetilwane: Lokusemkhatsini kwemakhemikhali lamahle, emaresini, kanye netintfo letikhutsatako
