Ndlela ya Oxalic Acid Khabohaydreti ya Oxidation
Ndlela leyi yitirhisa starch na chukele tani hi switirhisiwa swoka swinga lulamisiwanga naswona yi oxidize hi nitric acid eka 73–80 °C kuva yi humesa oxalic acid. Loko hi teka starch tani hi xikombiso, maendlelo ya endliwa hindlela leyi landzelaka: 85% mass fraction starch yi hangalasiwa eka aqueous solution leyingana 10% oxalic acid kumbe mother liquor ya switirhisiwa swin’wana swale xikarhi, yi hisiwa hi acid, naswona yi tlheriseriwa endzhaku kuringana 6 wa tiawara kuva yisungula ku kuma glucose ya xiendliwa xale xikarhi. Kutani, nitric acid na iron-vanadium catalyst swi cheriwa eka 63 °C kuva swiya emahlweni swiva na hydrolysis, naswona oxalic acid yikumeka hiku basisiwa endzhaku ka reaction.
Ku cinca lokukulu i hydrolysis ya starch kuva yiva glucose, leyi endzhaku yi oxidized kuya eka oxalic acid na nitric acid eka vukona bya
Fe 3+ na V2O5V
swihlohloteri. Endlelo leri ri kombisa switirhisiwa swoka swinga lulamisiwanga leswi kumekaka hiku olova, maendlelo yo olova, swiyimo swo olova swa matirhelo, na vuvekisi byale hansi, naswona matiko yanga hlawula switirhisiwa swohambana hambana kuya hi swiyimo swa wona swa switirhisiwa. Hikuya hi mbuyelo xikan’we na mbuyelo wa ikhonomi, corn starch hi xitalo i xihlawuhlawu xa kahle swinene. Hambiswiritano, swiphiqo swa yona swikatsa mbuyelo wale hansi, ku dyiwa ka mavele yotala, ntsengo wale henhla wa vuhumelerisi, na nhlayo leyikulu ya ti nitrogen oxides eka gasi ya ncila, leswingana chefu swinene naswona swivanga ku thyakisa mbango swinene.

Shandong Pulisi Chemical i muendli wa xiphurofexinali wa le China na muphakeri wa oxalic acid ya xiyimo xa le henhla ya indasitiri (dihydrate, H2C2O4·2H2O) leyi nga na 99.6% wa vutengi bya le hansi.

Textile & dyeing: Xitirhisiwa xo basisa, xipfuneti xo lulamisa mihlovo
Ku lulamisiwa ka dzovo: Tanning & de-ashing agent
Ku tshunguriwa ka nsimbi & ehenhla: Ku susa rust, ku susa swirhumbana, ku pholisha marble
Metallurgy: Xitirhisiwa xo khuluka xa ku humesiwa ka nsimbi ya misava leyi nga tolovelekangiki
Organic synthesis: Xiphemu xa le xikarhi xa tikhemikhali letinene, ti resins, na ti catalysts
