Njira Yokonzera Chakudya cha Oxalic Acid
Njira imeneyi imagwiritsa ntchito sitachi ndi shuga ngati zopangira ndipo imazisakaniza ndi nitric acid pa 73–80 °C kuti ipange oxalic acid. Mwachitsanzo, sitachi ndi motere: 85% ya sitachi imamwazidwa mu madzi okhala ndi 10% ya oxalic acid kapena mowa wa zinthu zina zapakati, kutenthedwa ndi asidi, ndikupukutidwa kwa maola 6 kuti shuga wapakati apezeke kaye. Kenako, nitric acid ndi chothandizira cha iron-vanadium zimawonjezedwa pa 63 °C kuti hydrolysis ipitirire, ndipo oxalic acid imapezeka kudzera mu kuyeretsa pambuyo pa reaction.
Yankho lalikulu ndi hydrolysis ya wowuma kukhala shuga, womwe umasinthidwa kukhala oxalic acid ndi nitric acid pamaso pa
Fe 3+ ndi V2O5V
zosakaniza. Njirayi ili ndi zinthu zopangira zomwe zikupezeka mosavuta, njira yosavuta, mikhalidwe yocheperako yogwirira ntchito, komanso ndalama zochepa, ndipo mayiko amatha kusankha zinthu zopangira zosiyanasiyana malinga ndi momwe zinthu zilili. Ponena za zokolola ndi phindu la zachuma, sitachi ya chimanga nthawi zambiri ndiyo chisankho chabwino kwambiri. Komabe, zovuta zake zimaphatikizapo zokolola zochepa, kugwiritsa ntchito tirigu wambiri, mtengo wokwera wopanga, komanso kuchuluka kwa nayitrogeni oxides mu mpweya wam'mbuyo, zomwe ndi poizoni kwambiri ndipo zimayambitsa kuipitsa chilengedwe.

Shandong Pulisi Chemical ndi kampani yaukadaulo yaku China yopanga komanso yogulitsa oxalic acid (dihydrate, H₂C₂O₄·2H₂O) yoyera kwambiri m'mafakitale yokhala ndi kuyera kocheperako kwa 99.6%.

Kupaka nsalu ndi utoto: Wothandizira kuyeretsa, wothandizira kukonza utoto
Kukonza chikopa: Chotsukira khungu ndi chotsukira phulusa
Kukonza zitsulo ndi pamwamba: Kuchotsa dzimbiri, kuchotsa mamba, kupukuta miyala ya marble
Metallurgy: Chothandizira kugwetsa zitsulo za rare earth
Kupanga kwachilengedwe: Pakati pa mankhwala abwino, ma resins, ndi ma catalysts
