Oxalic Acid Carbohydrate Oxidation Method
Yoo me tic ni tiyo ki jami ma ki lwongo ni starch ki cukal ma calo jami ma ki tiyo kwede ki loko gi ki nitric acid i 73-80 °C me yubu oxalic acid. Ka ki kwanyo gin ma ki lwongo ni starch ma calo labol, kit ma ki tiimo kwede tye kit man: 85% me pek pa gin ma ki lwongo ni starch ki poko i pii ma tye ki 10% oxalic acid onyo gin ma ki lwongo ni mother liquor pa jami mukene ma ki yubu, ki lyeto ki acid, ki ki dwoko cen pi cawa 6 me nongo glucose. I ngeye, nitric acid ki iron-vanadium catalyst ki medo i 63 °C pi medo hydrolysis, ki oxalic acid ki nongo ne ki i yubu ne inge tic ne.
Gin ma pire tek ma time en tye loko pa nyig cam ma ki lwongo ni starch me doko glucose, ma lacen loko doko oxalic acid ki nitric acid i kare ma tye
Fe 3+ ki V2O5V
catalysts. Yoo me tic man tye ki jami ma ki tiyo kwede ma nonge oyot, yoo ma yot, kit me tic ma yot, ki cente manok, ki lobe twero yero jami ma ki tiyo kwede ma pat pat malube ki kit ma jami gi tye kwede. I kom rwom me dongo ki adwogi me cente, nyig bel ma ki lwongo ni corn starch pol kare obedo gin maber loyo. Ento, peko ne tye iye kodi ma nok, camo nyig cam madwong, wel me yubu ne ma malo, ki wel nitrogen oxides madwong i yamo ma tye i ngeye, ma tye ki kwiri madwong ki balo kwo pa dano.

Shandong Pulisi Chemical tye dano ma ki ngeyo i lobo China ma gi yubu ki gi cato jami ma ki lwongo ni oxalic acid (dihydrate, H2C2O₄·2H2O) ma tye ki 99.6% ma rwom ne lapiny.

Bodo ki rangi: Gin ma weko rangi doko tar, gin ma konyo me loko rangi
Yub me del ler: Gin ma miyo del kom bedo macol ki kwanyo buru
Kit me yubu nyonyo ki kom ne: kwanyo nyal, kwanyo buru, yubu got ma ki lwongo ni marble
Metallurgy: Gin ma weko jami ma ki lwongo ni rare earth metal ma ki kwanyo ki i ngom
Kit ma ki yubu kwede jami ma kwo: Gin ma tye i kin jami ma ki yubu ki jami ma kwo, jami ma ki lwongo ni resins, ki catalysts
