Nzila ya Glyoxal Oxidation ya Oxalic Acid

Nzila ya Glyoxal Oxidation ya Oxalic Acid
Glyoxal ilakonzya kuchincha loko, aboobo ilakonzya kufwambaana kusanduka kuba oxalic acid mumulimo wa nitric acid. Akaambo katwaambo tulimbuli zintu zitabelesyegwi, muulo, anzila zyakupanga zintu, eeyi nzila tiikonzyi kuzundana kabotu mumusika alimwi tiiyakabelesyegwa mumafakitali.
Mukuyungizya, kuli nzila zimbi zyakupanga oxalic acid:
(1) Nzila yakubamba kaboni dioksayidi: Kaboni dioksayidi isaanguna kucheya kusika aakati-kati
CO2
mpawo akusandulwa kuba zintu zimwi zipona. Asidi ya oxalic ilajanwa kwiinda mukupa mumuni uuzwa mumulengalenga kwiinda mukubelesya nzila zya electrochemical alimwi a γ-rays, mumuni wazuba, naa malampi aa mercury aajisi nguzu kapati.
(2) Nzila yakunyengulula alkali kubelesya zintu zijisi ma cellulose: Musanganisyo wazintu zijisi ma cellulose (mbuli nkuni zisofweede, nkuni, azimwi) antoomwe a alkali muyumu uutakwe buumi zilanyengululwa antoomwe a 513-558 K kuti zipange oxalate yiinda ku 50%. Makristalu aa oxalate alanyonyooka kwiinda mukupanga mabwe, mpawo sulfuric acid ilabelesyegwa kujana oxalic acid. Eeyi nzila ilijisi nzila nguba yakubamba oxalic acid, pesi mweelwe wakusanduka kwawo uli munsi (munsi aa 35%), kubelesyegwa kwa alkali nkupati, mpawo kusofwaala kwabusena nkupati.
(3) Nzila yakupanga malasha aatabelesyegwi: Akapangwa kuzwa kuzisamu ziindene-indene mbuli zintu zitabelesyegwi. Mbuli chitondeezyo, oxalic acid ilapangwa kuzwa ku peat yamusyobo wa Sphagnum a Polytrichum kwiinda mukubelesya nitric acid oxidation. Kuchincha ooku kuchitwa a 343 K kwamahola aali 8-9, akuzwidilila kusika ku 95%. Eelyo zintu zitabelesyegwi mbuli bbwe lyamalasha nozibelesyegwa kupanga asidi ya oxalic, mweelwe ulasika ku 51%.

Shandong Pulisi Chemical Co., Ltd. – Oxalic Acid (Ethanedioic Acid) Syaazibwene

Shandong Pulisi Chemical, inkamu iisololela mukupanga misamu yakatalisyigwa mu 2006 ku Zibo, China, ilijisi luzibo lwakupanga oxalic acid iisalala loko akusambala nyika yoonse. Mulongo wesu wa oxalic acid ulaa zintu zyakupanga (99.6% min purity) antoomwe azyakulya (99.8% min purity), zilajanika mu dihydrate (H₂C₂O₄·2H₂O, CAS 6153-56-6) antoomwe a anhydrous (H₂C₂₂₄₂, CAS 174-64-6) kuzuzikizya ziyandikana zyamakwebo.

Yakabambilwa anzila zyakupanga zintu zisumpukide antoomwe akulanganya kabotu kweendelanya azyeelelo zya ISO 9001:2015, oxalic acid yesu itondezya busofwaazi busyoonto—sulfate ≤0.07%, heavy metals (Pb) ≤0.0005%, antoomwe a iron (Fe) ≤0.0005%—kusyomeka kwakubelesya. kuzwa kukusalazya nsimbi akusanzya chikumba kusikila kukusalazya maanzi akubamba chakulya. Tulijisi zipepa zyakuzumizya zibikkilizya kutobela milawu ya REACH akulembesya ku FAMI-QS, kutondezya kuti tulatobela milawu yanyika yoonse yakukwabilila alubono.

Kazibikkidwe mumasaka aa 25kg aa PP (akonzya kuchinchululwa a logo) kuti zibelesyegwe mumakwebo, oxalic acid yesu ilajanika kuti ituminwe kuzwa ku Qingdao, Tianjin, naa Shanghai. Katujisi nguzu zyakupanga matani aali 3,000 amwezi antoomwe akabunga ka R&D, tulapa nzila zipangidwe kabotu: maoda masyoonto, kupaka zintu kweelana ambomuyanda, alimwi akugwasyilizya kwabusongo mumapulojekiti aajatikizya basikuula. Mbuli sikusambala uusyomeka kumasi aatandila ku 30, tulabikkila maanu kukutola zintu muchiindi cheelede akwaambuuzyania kutakwe kampenda, eezi zipa kuti tube bantu bayandisi mukuula oxalic acid munyika yoonse.
