Glyoxal Oxidation Method of Oxalic Acid

Glyoxal Oxidation Method of Oxalic Acid
Glyoxal utiye ku kero mi dwoko piny, ci ecopu doko oxalic acid pio pio i the tic pa nitric acid ma tek. Ni lembe moko calu piny ma jucwalo, bei, man diro, yore eni utiye ku rwom ma lapiny mi pyem man podi jutiyo kudu ungo.
Mi medo, yore mukende utiye mi yubu oxalic acid:
(1) Yore mi yiko carbon dioxide: Carbon dioxide judwoko piny ni rwom ma piny
CO2
man edoko piny mukende ma kwo. Oxalic acid ju nwango ku tiyo ku yore mi electrochemical man γ-rays, lero pa ceng, nyo mac ma tek pa mercury.
(2) Yore mi lwoko alkali ma jutiyo kudu ku piny ma dwong ku cellulose: Rubu pa piny ma dwong ku cellulose (macalu yen, lum, man mukende mapol) man alkali ma tek ma rwinyo ngo juyike karacelu i 513-558 K mi wodhu oxalate ma kadhu 50%. Oxalate crystals juyike ku crystallization, man sulfuric acid jutiyo kudu pi nwangu oxalic acid. Yore eni utiye ku yore mayot mi yiko oxalic acid, ento rwom mi loko acel kende utiye piny (piny pa 35%), tic ku alkali utiye malo, man nyayu peko i kabedu utiye marac.
(3) Yore mi yubu piny ma tiyo ku makaa: Juyike ku peats matung tung calu piny ma tiyo kudu. Ku lapor, oxalic acid juyubu kud i peat pa genera Sphagnum man Polytrichum nikadhu kud i nitric acid oxidation. Lembe ne utimere i 343 K pi sawa 8-9, ku adwogi ma romo 95%. Ka jutiyo ku piny ma jutiyo kudu pi yubu oxalic acid, adwogi ne tuc 51%.

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

Shandong Pulisi Chemical, dul madit mi yiku kemikol ma juyike i 2006 i Zibo, China, timo tic mi yubu oxalic acid ma leng man poko piny i ng'om zoo. Piny mwa madit mi oxalic acid utiye ku rwom ma malu (99.6% min purity) man cam (99.8% min purity) ma tung tung, ma nwangre i dihydrate (H₂C₂O₄·2H₂O, CAS 6153-56-6) man anhydrous (H₂C₂₄₂₄, CAS 6153-56-6) rombu ku yeny mi tic matung tung.

Juyike ku diro mi yubu piny ma malu man gwoko leng pa piny ma lubu cik pa ISO 9001:2015, oxalic acid mwa nyuthu rwom ma piny pa piny ma rac—sulfate ≤0.07%, heavy metals (Pb) ≤0.0005%, man iron (Fe) ≤0.0005% pi bedo maber pa tic. nicaku i yweyu cuma man yiko adila nitundu i yweyu pii man yiku cam. Watiye ku waraga ma pire tek ma uketho i iye REACH compliance man FAMI-QS registration, ma nyutho nia walubo cik mi gwoko kwo man ber pa piny.

Juyike i 25kg PP bags (ma jucopu loko ku logo printing) pi wil madwong, oxalic acid mwa utiye pi FOB delivery kud i Qingdao, Tianjin, nyo Shanghai ports. Ku kero mi yubu piny 3,000 tons kubang dwi man jurutic mi R&D, wabe miyo kony ma juyike: lwongo ma nok, poko piny ma juyike, man kony mi tic pi tic ma jutimo ni juwil. Calu jumalworo piny ma jugeno i ngom ma kadhu 30, waketho yub mi kelo piny i kare man wec ma yot, ma weko wabedo piny maber pi wil mi oxalic acid i ng'om zoo.
