Indlela ye-Glyoxal Oxidation yaseShayina ye-Oxalic Acid efektri nabakhiqizi

Indlela Yokuxova I-Glyoxal ye-Oxalic Acid
I-Glyoxal inokwehliswa okukhulu, ngakho-ke ingafakwa ngokushesha ku-oxalic acid ngaphansi kwesenzo se-nitric acid enamandla efaka i-oxidizing. Ngenxa yezici ezifana nokutholakala kwezinto zokusetshenziswa, intengo, kanye nobuchwepheshe, le ndlela inokuncintisana okuncane emakethe futhi ayizange ithuthukiswe njengezimboni.
Ngaphezu kwalokho, kunezinye izindlela zokwenziwa ze-oxalic acid:
(1) Indlela yokulungiselela i-carbon dioxide: I-carbon dioxide iqale yehliswe ibe yi-medium
I-CO2
bese iguqulwa ibe ezinye izinto eziphilayo. I-oxalic acid itholakala ngokukhanyisa izinhlelo ezahlukene ze-carbon dioxide ngezindlela ze-electrochemical kanye nemisebe ye-γ, ukukhanya kwelanga, noma izibani ze-mercury ezinengcindezi ephezulu.
(2) Indlela yokuncibilikisa i-alkali kusetshenziswa izinto ezicebile nge-cellulose: Ingxube yezinto ezicebile nge-cellulose (njengezinkuni ezilahliwe, amakhoba, njll.) kanye ne-alkali eqinile engaphili iyancibilikiswa ku-513–558 K ukuze kukhiqizwe i-oxalate engaphezu kuka-50%. Amakristalu e-oxalate abangelwa yi-crystallization, bese kusetshenziswa i-sulfuric acid ukuthola i-oxalic acid eqediwe. Le ndlela inenqubo elula yokulungiselela i-oxalic acid, kodwa izinga lokuguqulwa kwe-single-pass liphansi (ngaphansi kuka-35%), ukusetshenziswa kwe-alkali kuphezulu, futhi ukungcola kwemvelo kubi kakhulu.
(3) Indlela yokukhiqiza izinto zokusetshenziswa kwamalahle: Kulungiselelwe kusuka kuma-peat ahlukahlukene njengezinto zokusetshenziswa. Isibonelo, i-oxalic acid ikhiqizwa kusuka kuma-peat esizukulwane i-Sphagnum ne-Polytrichum nge-nitric acid oxidation. Ukusabela kwenziwa ku-343 K amahora angu-8-9, ngesivuno esifinyelela ku-95%. Lapho izinto zokusetshenziswa ezifana ne-coal tar zisetshenziselwa ukukhiqiza i-oxalic acid, isivuno sifinyelela ku-51%.

I-Shandong Pulisi Chemical Co., Ltd. – Uchwepheshe we-Oxalic Acid (Ethanedioic Acid)

I-Shandong Pulisi Chemical, umkhiqizi wamakhemikhali ohamba phambili owasungulwa ngo-2006 eZibo, eShayina, igxile ekukhiqizweni kwe-oxalic acid ehlanzekile kakhulu kanye nokuhlinzekwa komhlaba wonke. Umugqa wethu womkhiqizo we-oxalic acid oyinhloko uqukethe izinhlobo zezinga lezimboni (ubumsulwa obungu-99.6% min) kanye nezinga lokudla (ubumsulwa obungu-99.8% min), ezitholakala kokubili ngezindlela ze-dihydrate (H₂C₂O₄·2H₂O, CAS 6153-56-6) kanye ne-anhydrous (H₂C₂O₄, CAS 144-62-7) ukuze kuhlangatshezwane nezidingo zezimboni ezahlukahlukene.

Yakhiwe ngobuchwepheshe bokukhiqiza obuthuthukisiwe kanye nokulawulwa kwekhwalithi okuqinile okuhambisana namazinga e-ISO 9001:2015, i-oxalic acid yethu ibonisa amazinga aphansi okungcola—i-sulfate ≤0.07%, izinsimbi ezisindayo (Pb) ≤0.0005%, kanye ne-iron (Fe) ≤0.0005%—okuqinisekisa ukuthembeka kwezicelo kusukela ekuhlanzeni insimbi kanye nokushiswa kwesikhumba kuya ekuhlanzweni kwamanzi kanye nokucubungula ukudla. Sinezitifiketi ezigunyaziwe ezifaka phakathi ukuhambisana ne-REACH kanye nokubhaliswa kwe-FAMI-QS, okuqinisekisa ukunamathela kwethu ezindinganisweni zokuphepha zomhlaba wonke kanye nekhwalithi.

Ipakishwe ngezikhwama ze-PP ezilukiwe ezingama-25kg (ezingenziwa ngezifiso ngokunyathelisa ilogo) zama-oda amakhulu ezimboni, i-oxalic acid yethu iyatholakala ukuze ilethwe yi-FOB kusuka emachwebeni aseQingdao, eTianjin, noma eShanghai. Njengoba sinamandla okukhiqiza anyanga zonke angamathani angu-3,000 kanye nethimba le-R&D elizinikele, sinikeza izixazululo ezenzelwe wena: ama-oda amancane, ukupakishwa okwenziwe ngokwezifiso, kanye nokusekelwa kobuchwepheshe kwamaphrojekthi athile kumakhasimende. Njengomhlinzeki othembekile emazweni angaphezu kuka-30, sibeka phambili izinto ezifika ngesikhathi kanye nokuxhumana okusobala, okwenza sibe yisinqumo esikhethwayo sokuthengwa kwe-oxalic acid emhlabeni jikelele.
