Nzira yeGlyoxal Oxidation yeOxalic Acid
Glyoxal inogona kuderedzwa zvakanyanya, saka inogona kukurumidza kuoxidized kuita oxalic acid pasi pesimba re nitric acid ine oxidizing. Nekuda kwezvinhu zvakaita sekuwanikwa kwezvinhu zvakagadziriswa, mutengo, uye tekinoroji, nzira iyi haina kukwikwidzana kwakanaka pamusika uye haina kugadzirwa nemaindasitiri.
Pamusoro pezvo, kune dzimwe nzira dzekugadzira dze oxalic acid:
(1) Nzira yekugadzirira carbon dioxide: Carbon dioxide inotanga yaderedzwa kusvika pakati
CO2
uye yozoshandurwa kuita zvimwe zvinhu zvipenyu. Oxalic acid inowanikwa nekuvhenekesa masisitimu akasiyana-siyana ecarbon dioxide uchishandisa nzira dzemagetsi uye γ-rays, chiedza chezuva, kana marambi emercury ane simba guru.
(2) Nzira yekunyungudutsa alkali uchishandisa zvinhu zvakapfuma mu cellulose: Musanganiswa wezvinhu zvakapfuma mu cellulose (zvakadai sehuni dzakaraswa, hupfu, nezvimwewo) uye inorganic strong alkali zvinonyungudutswa pamwe chete pa 513–558 K kuti zvigadzire oxalate inopfuura 50%. Makristalo e oxalate anokonzereswa ne crystallization, uye sulfuric acid inoshandiswa kuwana oxalic acid yakapedzwa. Nzira iyi ine nzira iri nyore yekugadzira oxalic acid, asi chiyero chekuchinja kwe single-pass chakaderera (pasi pe 35%), kushandiswa kwealkali kwakakwira, uye kusvibiswa kwezvakatipoteredza kwakanyanya.
(3) Nzira yekugadzira marasha: Yakagadzirwa kubva kumapeat akasiyana-siyana sezvinhu zvisina kugadzirwa. Semuenzaniso, oxalic acid inogadzirwa kubva kumapeat erudzi rweSphagnum nePolytrichum kuburikidza ne nitric acid oxidation. Kuita uku kunoitika pa343 K kwemaawa 8-9, negoho rinosvika 95%. Kana zvinhu zvisina kugadzirwa zvakaita se coal tar zvichishandiswa kugadzira oxalic acid, goho rinosvikawo 51%.

Shandong Pulisi Chemical Co., Ltd. – Nyanzvi yeOxalic Acid (Ethanedioic Acid)

Shandong Pulisi Chemical, kambani inotungamira mukugadzira makemikari yakavambwa muna 2006 muZibo, China, inonyanya kugadzira oxalic acid yakachena uye inowanikwa pasi rose. Kambani yedu huru yezvigadzirwa zve oxalic acid ine mhando dzemhando yeindasitiri (99.6% min purity) uye mhando dzemhando yefood (99.8% min purity), inowanikwa mumhando dzese dze dihydrate (H₂C₂O₄·2H₂O, CAS 6153-56-6) uye anhydrous (H₂C₂O₄, CAS 144-62-7) kuti igutse zvinodiwa nemaindasitiri zvakasiyana-siyana.

Yakagadzirwa nehunyanzvi hwekugadzira hwepamusoro uye kudzora kwakasimba kwemhando zvinoenderana neISO 9001:2015 standards, oxalic acid yedu inoratidza kusachena kwakaderera—sulfate ≤0.07%, heavy metals (Pb) ≤0.0005%, uye iron (Fe) ≤0.0005%—zvichivimbisa kuvimbika kwezvishandiso kubva pakuchenesa simbi nekuchenesa dehwe kusvika pakuchenesa mvura nekugadzira chikafu. Tine zvitupa zvine mvumo zvinosanganisira REACH compliance uye FAMI-QS registration, zvichisimbisa kutevedzera kwedu mitemo yekuchengetedzeka kwenyika dzese uye yemhando yepamusoro.

Yakaputirwa mumabhegi ePP akarukwa e25kg (anogona kugadziriswa nekudhinda logo) ekutenga zvinhu zvakawanda mumaindasitiri, oxalic acid yedu inowanikwa kuti itumirwe kubva kuQingdao, Tianjin, kana Shanghai ports. Tiine kugona kwekugadzira kwematani 3,000 pamwedzi uye timu yeR&D yakatsaurirwa, tinopa mhinduro dzakagadzirirwa isu: maodha madiki, kurongedza kwakagadzirirwa isu, uye rutsigiro rwehunyanzvi kumapurojekiti anoenderana nevatengi vedu. Semutengesi akavimbika kunyika dzinopfuura 30, tinokoshesa mafambiro ebasa nenguva uye kutaurirana pachena, zvichiita kuti tive sarudzo inosarudzwa yekutenga oxalic acid pasi rose.
