Cov txheej txheem oxidation no zoo ib yam li txoj kev oxidation hmoov txhuv nplej siab. Cov kua dej ethylene glycol raug cua sov rau 60 ° C, thiab cov kua qaub sib xyaw (30% -40% sulfuric acid los ntawm qhov hnyav, 20% -25% nitric acid los ntawm qhov hnyav) thiab vanadium pentoxide raug ntxiv rau hauv qab kev sib xyaw ua ke. Kev oxidation yog nqa tawm ntawm 50-70 ° C thiab 1.3-4.0 kPa. Cov khoom raug txias, crystallized, thiab lim kom tau txais oxalic acid nrog qhov huv ntawm 99.9% thiab cov txiaj ntsig ntawm ntau dua 90%. Txoj kev no tuaj yeem ua tiav hauv peb qhov xwm txheej txheej txheem: qhov siab ntawm huab cua, txo qhov siab, thiab nce qhov siab. Nws muaj cov txheej txheem yooj yim, cov txiaj ntsig oxalic acid siab, cov khoom zoo, thiab yuav luag tag nrho rov qab los ntawm nitric acid, tab sis tus nqi khoom siv raw siab.
