Makhalidwe a Kapangidwe ka Maselo a Oxalic Acid

Kapangidwe ka molekyulu ya oxalic acid ndiye maziko a mankhwala ake. Mwa kapangidwe kake, oxalic acid imakhala ndi magulu awiri a carboxyl (-COOH) ogwirizana mwachindunji, omwe amatha kuyimiridwa ndi fomula yofupikitsidwa ya HOOC-COOH. Gulu lililonse la carboxyl limapangidwa ndi gulu la carbonyl (C=O) ndi gulu la hydroxyl (-OH), kapangidwe kamene kamapatsa oxalic acid makhalidwe wamba a dicarboxylic acid.

Mu mkhalidwe wa kristalo, mamolekyu a oxalic acid amapanga dongosolo lapadera kudzera mu hydrogen bonding. Kafukufuku wa X-ray diffraction akuwonetsa kuti anhydrous oxalic acid ilipo m'mitundu iwiri ya kristalo: α-form (makristalo a rhombic) ndi β-form (monoclinic system). Dihydrated oxalic acid imapanga kapangidwe ka monoclinic, komwe mamolekyu amadzi ndi mamolekyu a oxalic acid amapanga netiweki yovuta yolumikizira hydrogen. Kapangidwe kameneka kakufotokoza chifukwa chake makristalo a oxalic acid amataya madzi awo oundana kaye akatenthedwa.

Kuchokera pa kapangidwe ka zamagetsi, maatomu a kaboni mu oxalic acid ali ndi mkhalidwe wa okosijeni wa +3, mkhalidwe wapakati wa valence. Izi zimapatsa oxalic acid zonse mphamvu zina zokosijeni komanso mphamvu zochepetsera, ndipo mphamvu zochepetsera zimalamulira machitidwe ambiri othandiza. Mu molekyulu, kutalika kwa mgwirizano wa kaboni-kaboni ndi 1.54 Å, mgwirizano wa kaboni-oksijeni ndi 1.20 Å, ndipo mgwirizano umodzi wa kaboni-oksijeni ndi 1.31 Å. Deta ya kutalika kwa mgwirizanowu ikuwonetsa kugawa kwa ma elekitironi mkati mwa molekyulu.

Zibo Anhao Chemical Co., Ltd. imapereka Oxalic Acid yapamwamba kwambiri (Ethanedioic Acid, CAS 144-62-7 anhydrous / 6153-56-6 dihydrate) — dicarboxylic acid yosavuta kwambiri yokhala ndi molecular formula (COOH)₂, yokhala ndi 99.6% kuyera kocheperako komanso kapangidwe ka kristalo kogwirizana. Yopangidwa kudzera mu njira zoyeretsera za sodium formate, oxalic acid yathu ndi yoyera, yopanda fungo, yosungunuka kwambiri m'madzi ndi ethanol, yokhala ndi mphamvu zochepetsera komanso mphamvu yabwino kwambiri yoyeretsera zitsulo. Timapereka mitundu yonse ya anhydrous ndi dihydrate, yopakidwa m'matumba opangidwa ndi nsalu a 25kg okhala ndi ma inner liners kapena ma IBC totes a 1000kg, opangidwa kuti azitsuka mafakitale, utoto wa nsalu, chithandizo cha pamwamba pa zitsulo, komanso zofunikira pakupanga zinthu zachilengedwe. QC yolimba mkati ndi zikalata zonse zotsatizana (COA, MSDS, REACH) zimatsimikizira mtundu wokhazikika kwa ogula padziko lonse lapansi. Monga kampani yodalirika yopanga oxalic acid ku China, timaphatikiza mitengo yopikisana, kuchuluka kwa maoda osinthika, komanso chithandizo chodalirika cha zinthu kuti tilimbikitse ntchito zanu zamafakitale padziko lonse lapansi.
