Oxalic Acid 99.6% mphindi
Mwachilengedwe, asidi wa Oxalic amawoneka ngati mbale yopanda utoto ya monoclinic kapena makhiristo a prismatic, kapena ufa woyera. Asidi wa Oxalic wopangidwa ndi njira za okosijeni ndi wopanda fungo, pomwe wochokera mu njira zopangira akhoza kukhala ndi fungo losiyana. Amasungunuka pa 150–160°C ndipo amatuluka mumlengalenga wotentha komanso wouma. Kapangidwe kake ka kusungunuka ndi kodziwika bwino: 1 g imasungunuka mu madzi a 7 mL, 2 mL madzi otentha, 2.5 mL ethanol, 1.8 mL boiling ethanol, 100 mL ether, kapena 5.5 mL glycerol, koma sasungunuka mu benzene, chloroform, ndi petroleum ether. Yankho la 0.1 mol/L lili ndi pH ya 1.3. Kuchuluka kwake (pa 18.54°C) ndi 1.653, ndi malo osungunuka a 101–102°C (ya dihydrate) kapena 187°C (mtundu wa anhydrous). Imagawidwa ngati yopanda poizoni wambiri, yokhala ndi LD₅₀ (kalulu) wa khungu wa 2000 mg/kg.
Zibo Anhao Chemical Co., Ltd. – High Purity Oxalic Acid (Dihydrate)
Zibo Anhao Chemical Co., Ltd. ndi kampani yodalirika yaku China yogulitsa komanso kutumiza kunja oxalic acid (H₂C₂O₄·2H₂O, dihydrate) yomwe ili ndi likulu lake ku Zibo, Shandong Province, komwe ndi malo ofunikira kwambiri a mankhwala kumpoto kwa China. Oxalic acid yathu imapangidwa motsatira njira zowongolera khalidwe, yokhala ndi chiyero cha 99.6% min, chinyezi chochepa, komanso mawonekedwe okhazikika a kristalo, zomwe zimaonetsetsa kuti ogwiritsa ntchito mafakitale padziko lonse lapansi agwira ntchito nthawi zonse.
Oxalic acid yathu imagwira ntchito ngati organic acid yogwiritsidwa ntchito kwambiri poyeretsa nsalu, kupukuta khungu, kukonza pamwamba pa chitsulo, kupukuta miyala ya marble, kuchotsa nthaka yosowa, komanso kupanga mankhwala achilengedwe. Imagwira ntchito ngati chothandizira kuchotsa ma scaling, kuchotsa dzimbiri, komanso chothandizira kuchepetsa, kuthandizira kupanga bwino m'mafakitale osiyanasiyana.
Ndi zaka zoposa 10 zaukadaulo wotumiza mankhwala kunja, Anhao Chemical imapereka ma CD osinthika (matumba 25kg kapena osinthidwa), mphamvu yokhazikika yoperekera, komanso chithandizo chaukadaulo cholemba zikalata kuti zikwaniritse miyezo yapadziko lonse lapansi yotumizira kunja. Timaika patsogolo mgwirizano wa nthawi yayitali ndikupereka zabwino nthawi zonse pamitengo yopikisana.
