Txoj Kev Oxalic Acid Carbohydrate Oxidation
Txoj kev no siv cov hmoov txhuv nplej siab thiab suab thaj ua cov khoom siv raw thiab oxidizes lawv nrog nitric acid ntawm 73–80 ° C los tsim cov oxalic acid. Piv txwv li, coj cov hmoov txhuv nplej siab ua piv txwv, cov txheej txheem yog raws li nram no: 85% pawg feem hmoov txhuv nplej siab tau tawg ua cov kua dej uas muaj 10% oxalic acid lossis cov dej cawv ntawm lwm cov khoom nruab nrab, cua sov nrog kua qaub, thiab refluxed rau 6 teev kom tau txais cov khoom nruab nrab glucose ua ntej. Tom qab ntawd, nitric acid thiab cov hlau-vanadium catalyst ntxiv rau ntawm 63 ° C rau kev hydrolysis ntxiv, thiab oxalic acid tau txais los ntawm kev ua kom zoo tom qab kev tshuaj tiv thaiv.
Qhov tshuaj tiv thaiv tseem ceeb yog hydrolysis ntawm cov hmoov txhuv nplej siab rau hauv qabzib, uas tom qab ntawd oxidized rau oxalic acid nrog nitric acid nyob rau hauv lub xub ntiag ntawm
Fe3+ thiab V2O5V
cov tshuaj catalysts. Txoj kev no muaj cov khoom siv raw yooj yim, cov txheej txheem yooj yim, cov xwm txheej ua haujlwm tsis hnyav, thiab kev nqis peev tsawg, thiab cov tebchaws tuaj yeem xaiv cov khoom siv raw sib txawv raws li lawv cov peev txheej. Hais txog cov txiaj ntsig thiab kev lag luam, hmoov txhuv nplej siab feem ntau yog qhov kev xaiv zoo tshaj plaws. Txawm li cas los xij, nws qhov tsis zoo suav nrog cov txiaj ntsig qis, kev noj cov nplej ntau, cov nqi tsim khoom siab, thiab ntau cov nitrogen oxides hauv cov pa roj, uas muaj tshuaj lom heev thiab ua rau muaj kuab paug rau ib puag ncig.

Shandong Pulisi Chemical yog cov kws tshaj lij Suav teb chaw tsim khoom thiab cov khoom siv ntawm cov tshuaj oxalic acid (dihydrate, H₂C₂O₄·2H₂O) nrog 99.6% qhov huv si tsawg kawg nkaus.
