Ethylene Glycol Nitric Acid Oxidation Method of Oxalic Acid
Lembe maeni mi oxidation urombo ku yore mi oxidation mi starch. Ethylene glycol ma pii pii juyike i 60 °C, man acid ma judubo (30%–40% sulfuric acid ku pek, 20%–25% nitric acid ku pek) man vanadium pentoxide jumedo ku tego ma tek. Oxidation utimere i 50-70 °C man 1.3-4.0 kPa. Jam piny ne juyike, juyike, man juyike pi nwangu oxalic acid ku leng pa 99.9% man ku rwom ma kadhu 90%. Yore maeni copu bedu i thenge adek: tegu pa yamu, tego ma nok, man tego ma malu. Etiye ku yore mayot, oxalic acid madwong, piny maber, man dwoko nitric acid, ento bei piny ma jutiyo kudu utiye malo.

Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate – Industrial Grade 99.6% Purity
Shandong Pulisi Chemical Co., Ltd., juyiku man jucwalo kemikol ma jugeno nicaku i 2006, timo tic mi yubu oxalic acid dihydrate (H2C2O₄·2H2O, CAS 6153-56-6, EINECS 2053-63) ku rwom ma malu. Oxalic acid mwa ma rwom pare lapiny utiye ku leng pa piny ma romo 99.6%, nen calu buru ma tar ma nen ungo (sulfate ≤0.1%, heavy metals ≤0.002%, iron ≤0.003%). Jutiyo kudu lee i goyo bongo man rangi, yubu adila, lwoko wi cuma, lwoko marble, lwoko pii, kwanyo piny ma nyai ungo, man yubu yath.
Wagwoko piny madwong ma watiye kudu i Shandong warehouse, ma weko wacwalo piny madwong pio pio. Kit mi kethu piny ma yot (25kg, 50kg, 1000kg bags) man cwalo piny iwi ngom zoo kud i Qingdao, Tianjin, nyo Shanghai ports ketho jucwalo piny iwi ngom zoo i kare ma mitire. Wamiyo kony mi tic, waraga mi COA/MSDS, man bei maber pi rombu ku yeny mi tic matung tung.
Lwong wa tin pi wel ma juyike man gwoko yore peri mi oxalic acid.
