Indlela yokuOxidation ye-Oxalic Acid ye-Ethylene Glycol Nitric Acid
Le nkqubo yokunyibilikisa ifana kakhulu nendlela yokunyibilikisa istatshi. Isisombululo se-ethylene glycol esimanzi sitshiswa ukuya kuma-60 °C, kwaye i-asidi exutyiweyo (30%–40% ye-sulfuric acid ngobunzima, 20%–25% ye-nitric acid ngobunzima) kunye ne-vanadium pentoxide zongezwa phantsi kokuxutywa ngamandla. Ukunyibilikisa kwenziwa kwi-50–70 °C kunye ne-1.3–4.0 kPa. Imveliso iyapholiswa, yenziwe ikristale, kwaye ihluzwe ukuze kufunyanwe i-oxalic acid enobumsulwa be-99.9% kunye nesivuno esingaphezulu kwe-90%. Le ndlela inokwenziwa phantsi kweemeko ezintathu zenkqubo: uxinzelelo lomoya, uxinzelelo oluncitshisiweyo, kunye noxinzelelo olunyukileyo. Inenkqubo elula, isivuno esiphezulu se-oxalic acid, umgangatho wemveliso olungileyo, kunye nokubuyiselwa phantse ngokupheleleyo kwe-nitric acid, kodwa ixabiso lezinto eziluhlaza liphezulu.

I-Shandong Pulisi Chemical Co., Ltd. I-Oxalic Acid Dihydrate – Umgangatho woShishino 99.6% Ubumsulwa
I-Shandong Pulisi Chemical Co., Ltd., umenzi weekhemikhali othembekileyo nothumela kwamanye amazwe ukususela ngo-2006, igxile ekuveliseni i-oxalic acid dihydrate ecocekileyo kakhulu (H₂C₂O₄·2H₂O, CAS 6153-56-6, EINECS 205-634-3) ngolawulo olungqongqo lomgangatho. I-oxalic acid yethu yodidi lweshishini iqhayisa ngobumsulwa obuncinci be-99.6%, ibonakala njengomgubo omhlophe wekristale onamanqanaba aphantsi okungcola (i-sulfate ≤0.1%, iintsimbi ezinzima ≤0.002%, isinyithi ≤0.003%). Isetyenziswa kakhulu ekuprinteni nasekudayeni impahla yelaphu, ekucutshungulweni kwesikhumba, ekucoceni umphezulu wesinyithi, ekupolisheni imabula, ekunyangweni kwamanzi, ekukhutshweni komhlaba ongaqhelekanga, nakwi-pharmaceutical intermediate synthesis.
Sigcina uluhlu olukhulu lwezinto ezikhoyo kwivenkile yethu yaseShandong, nto leyo evumela ukuthunyelwa ngokukhawuleza kwee-odolo ezinkulu. Iindlela zokupakisha eziguquguqukayo (iingxowa ezingama-25kg, ezingama-50kg, ezili-1000kg) kunye nokuthunyelwa kwehlabathi jikelele ukusuka kwizibuko zaseQingdao, eTianjin, okanye eShanghai ziqinisekisa ukuhanjiswa ngexesha elifanelekileyo kwihlabathi liphela. Sinikezela ngenkxaso epheleleyo yobugcisa, amaxwebhu e-COA/MSDS, kunye namaxabiso akhuphisanayo ukuhlangabezana neemfuno ezahlukeneyo zoshishino.
Qhagamshelana nathi namhlanje ukuze ufumane ikowuteshini eyenzelwe wena kwaye ukhusele uthotho lwakho lwe-oxalic acid.
