Njira Yopangira Oxalic Acid ya Ethylene Glycol Nitric Acid
Njira yothira okosijeni iyi ndi yofanana kwambiri ndi njira yothira okosijeni ya starch. Madzi a ethylene glycol amatenthedwa kufika pa 60 °C, ndipo asidi wosakaniza (30%–40% sulfuric acid ndi kulemera, 20%–25% nitric acid ndi kulemera) ndi vanadium pentoxide amawonjezedwa pansi pa kusakaniza kwamphamvu. Kuthira okosijeni kumachitika pa 50–70 °C ndi 1.3–4.0 kPa. Chogulitsacho chimaziziritsidwa, kukonzedwa, ndikusefedwa kuti chipeze oxalic acid yokhala ndi chiyero cha 99.9% ndi zokolola zoposa 90%. Njirayi ikhoza kuchitika pansi pa mikhalidwe itatu ya ndondomeko: kuthamanga kwa mpweya, kupanikizika kochepa, ndi kupanikizika kowonjezereka. Ili ndi njira yosavuta, kuchuluka kwa oxalic acid, khalidwe labwino la chinthu, komanso kuchira kwathunthu kwa nitric acid, koma mtengo wazinthu zopangira ndi wokwera.

Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate – Industrial Giredi 99.6% Purity
Shandong Pulisi Chemical Co., Ltd., kampani yodalirika yopanga mankhwala komanso kutumiza kunja kuyambira mu 2006, imadziwika kwambiri popanga oxalic acid dihydrate yoyera kwambiri (H₂C₂O₄·2H₂O, CAS 6153-56-6, EINECS 205-634-3) ndi kuwongolera bwino kwambiri khalidwe. Oxalic acid yathu yapamwamba kwambiri imakhala ndi chiyero chocheperako cha 99.6%, imawoneka ngati ufa woyera wa kristalo wokhala ndi zodetsa zochepa (sulfate ≤0.1%, zitsulo zolemera ≤0.002%, chitsulo ≤0.003%). Imagwiritsidwa ntchito kwambiri posindikiza ndi kupaka utoto nsalu, kukonza chikopa, kuyeretsa pamwamba pa chitsulo, kupukuta miyala ya marble, kukonza madzi, kuchotsa nthaka yachilendo, komanso kupanga mankhwala apakatikati.
Timasunga zinthu zambiri zomwe zili m'sitolo yathu ya Shandong, zomwe zimathandiza kuti katundu wathu atumizidwe nthawi yomweyo kuti akagulidwe katundu wambiri. Zosankha zosinthika zolongedza (matumba 25kg, 50kg, 1000kg) komanso kutumiza katundu padziko lonse lapansi kuchokera ku madoko a Qingdao, Tianjin, kapena Shanghai zimathandiza kuti katundu wathu atumizidwe nthawi yake padziko lonse lapansi. Timapereka chithandizo chaukadaulo chokwanira, zikalata za COA/MSDS, komanso mitengo yopikisana kuti tikwaniritse zosowa zosiyanasiyana zamafakitale.
Lumikizanani nafe lero kuti mupeze mtengo wokonzedwa mwamakonda ndikuteteza unyolo wanu wa oxalic acid.
