Indlela ye-Oxalic Acid yeGlyoxal Oxidation
I-Glyoxal inamandla okunciphisa ulwelo, ngoko ke inokunyibilikiswa ngokukhawuleza ibe yi-oxalic acid phantsi kwesenzo se-nitric acid enamandla oxidizing. Ngenxa yezinto ezifana nokubonelela ngezinto eziluhlaza, ixabiso, kunye netekhnoloji, le ndlela ayinakho ukukhuphisana okuhle kwimarike kwaye ayizange iphuhliswe kwimizi-mveliso.
Ukongeza, kukho ezinye iindlela zokwenziwa ze-oxalic acid:
(1) Indlela yokulungiselela i-carbon dioxide: I-carbon dioxide iqale yehliswe ibe yi-medium
I-CO2
ize emva koko iguqulwe ibe zezinye izinto eziphilayo. I-oxalic acid ifunyanwa ngokukhanyisela iinkqubo ezahlukeneyo zekhabhoni diokside ngeendlela ze-electrochemical kunye ne-γ-rays, ukukhanya kwelanga, okanye izibane zemercury ezinoxinzelelo oluphezulu.
(2) Indlela yokunyibilikisa i-alkali kusetyenziswa izinto ezityebileyo kwi-cellulose: Umxube wezinto ezityebileyo kwi-cellulose (ezifana neenkuni ezilahliweyo, umququ, njl.njl.) kunye ne-alkali enamandla e-inorganic iyanyibilikiswa kwi-513–558 K ukuvelisa i-oxalate engaphezulu kwe-50%. Iikristale ze-oxalate zibangelwa yi-crystallization, emva koko i-sulfuric acid isetyenziselwa ukufumana i-oxalic acid egqityiweyo. Le ndlela inenkqubo elula yokulungiselela i-oxalic acid, kodwa izinga lokuguqulwa kwe-single-pass liphantsi (ngaphantsi kwe-35%), ukusetyenziswa kwe-alkali kuphezulu, kwaye ungcoliseko lokusingqongileyo lubi kakhulu.
(3) Indlela yokuvelisa izinto eziluhlaza zamalahle: Zilungiselelwe kwiipeat ezahlukeneyo njengezinto eziluhlaza. Umzekelo, i-oxalic acid iveliswa kwipeat ye-genera Sphagnum kunye nePolytrichum nge-nitric acid oxidation. I-reaction yenziwa kwi-343 K kangangeeyure ezi-8-9, kunye nesivuno esifikelela kwi-95%. Xa izinto eziluhlaza ezifana ne-coal tar zisetyenziselwa ukuvelisa i-oxalic acid, isivuno sifikelela kwi-51%.

I-Shandong Pulisi Chemical Co., Ltd. – Ingcali ye-Oxalic Acid (Ethanedioic Acid)

I-Shandong Pulisi Chemical, umenzi weekhemikhali ophambili owasekwa ngo-2006 eZibo, eTshayina, igxile kwimveliso ye-oxalic acid ecocekileyo kakhulu kunye nokunikezelwa kwehlabathi. Umgca wethu wemveliso ye-oxalic acid ephambili uneendidi zezinga lemizi-mveliso (99.6% min purity) kunye nezinga lokutya (99.8% min purity), ezifumaneka kwiifom ze-dihydrate (H₂C₂O₄·2H₂O, CAS 6153-56-6) kunye ne-anhydrous (H₂C₂O₄, CAS 144-62-7) ukuhlangabezana neemfuno ezahlukeneyo zoshishino.

Yenziwe ngetekhnoloji yemveliso ephucukileyo kunye nolawulo oluqinileyo lomgangatho oluhambelana nemigangatho ye-ISO 9001:2015, i-oxalic acid yethu ibonisa amanqanaba aphantsi okungcola—i-sulfate ≤0.07%, iintsimbi ezinzima (Pb) ≤0.0005%, kunye ne-iron (Fe) ≤0.0005%—ukuqinisekisa ukuthembeka kwezicelo eziqala ekucoceni isinyithi kunye nokutshiswa kwesikhumba ukuya kunyango lwamanzi kunye nokulungiswa kokutya. Sineziqinisekiso ezigunyazisiweyo kubandakanya ukuthotyelwa kwe-REACH kunye nobhaliso lwe-FAMI-QS, ukuqinisekisa ukuthotyelwa kwethu kwimigangatho yokhuseleko lwamazwe ngamazwe kunye nomgangatho.

Ipakishwe kwiingxowa ze-PP ezilukiweyo ezingama-25kg (ezinokwenziwa ngokwezifiso kunye nokuprintwa kwelogo) kwiiodolo ezinkulu zemizi-mveliso, i-oxalic acid yethu iyafumaneka ukuze ihanjiswe kwi-FOB evela kwizibuko zaseQingdao, eTianjin, okanye eShanghai. Ngomthamo wemveliso wenyanga weetoni ezingama-3,000 kunye neqela elizinikeleyo le-R&D, sinikezela ngezisombululo ezenzelwe wena: ii-odolo ezincinci, ukupakishwa okwenziwe ngokwezifiso, kunye nenkxaso yobugcisa kwiiprojekthi ezithile zabathengi. Njengomthengisi othembekileyo kumazwe angaphezu kwama-30, sibeka phambili izinto ezilungiselelwe ngexesha elifanelekileyo kunye nonxibelelwano olucacileyo, nto leyo esenza sibe lolona khetho lukhethwayo lokuthengwa kwe-oxalic acid kwihlabathi liphela.
