Ethylene Glycol Ndlela ya Oxidation ya Nitric Acid ya Oxalic Acid
Endlelo leri ra oxidation rifana swinene na ndlela ya starch oxidation. Nkatsakanyo wa ethylene glycol wa mati wu hisiwa kuya eka 60 °C, naswona acid leyi pfanganisiweke (30%–40% sulfuric acid hi vukulu, 20%–25% nitric acid hi vukulu) na vanadium pentoxide swi cheriwa ehansi ka ku hlanganisiwa hi matimba. Oxidation yi endliwa eka 50–70 °C na 1.3–4.0 kPa. Xiendliwa lexi xi kufumetiwa, xi crystallized, naswona xi sefiwa kuva xikuma oxalic acid leyi tengeke ya 99.9% xikan’we na mbuyelo wo tlula 90%. Ndlela leyi yinga endliwa ehansi ka swiyimo swinharhu swa maendlelo: ntshikelelo wa xibakabaka, ntshikelelo lowu hungutiweke, na ntshikelelo lowu engetelekeke. Yina endlelo ro olova, mbuyelo wale henhla wa oxalic acid, khwalithi ya kahle ya swihumelerisiwa, naswona kwalomu ka ku vuyiseriwa loku heleleke ka nitric acid, kambe nxavo wa raw material wule henhla.

Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate – Giredi ya Tiindasitiri 99.6% Ku basa
Shandong Pulisi Chemical Co., Ltd., muendli wa tikhemikhali loyi a tshembekaka na muxavisi wa matiko mambe kusukela hi 2006, yi tiveka ngopfu eka ku humelerisa oxalic acid dihydrate ya vutengi byale henhla (H2C2O4·2H2O, CAS 6153-56-6, EINECS 205-634-3) na vulawuri byo tika bya khwalithi. Oxalic acid ya hina ya grade ya ti indasitiri yi tinyungubyisa hi ku basa ka le hansi ka 99.6%, yi vonaka tani hi powder yo basa ya crystalline leyingana ti levele tale hansi ta thyaka (sulfate ≤0.1%, tinsimbi to tika ≤0.002%, iron ≤0.003%). Yi tirhisiwa ngopfu eka ku kandziyisa ka swiambalo & ku daya, ku lulamisiwa ka dzovo, ku basisa ehenhla ka nsimbi, ku pholisha marble, ku basisiwa ka mati, ku humesiwa ka misava leyi nga tolovelekangiki, na ku endliwa ka swilo swa le xikarhi swa mirhi.
Hi hlayisa nhundzu leyikulu leyi nga exitokweni eka ndhawu ya hina yo hlayisela swilo ya le Shandong, leswi endlaka leswaku ku rhumeriwa hi xihatla eka tioda ta vunyingi. Tindlela to paka leti cinca-cincaka (25kg, 50kg, 1000kg bags) na ku rhumeriwa ka misava hinkwayo kusuka eka swikepe swa Qingdao, Tianjin, kumbe Shanghai switiyisisa ku rhumeriwa hi nkarhi emisaveni hinkwayo. Hi nyika nseketelo wa xithekiniki lowu heleleke, matsalwa ya COA/MSDS, na minxavo yo phikizana ku fikelela swilaveko swo hambana swa tiindasitiri.
Tihlanganisi na hina namuntlha ku kuma xikombelo lexi endleriweke wena naswona u sirhelela mphakelo wa wena wa oxalic acid.
