Ethylene Glycol Nitric Acid atanga Oxalic Acid oxidation hman dan
He oxidation process hi starch oxidation method nen hian a inang hle. Aqueous ethylene glycol solution chu 60 °C-ah a lum a, mixed acid (30%–40% sulfuric acid by mass, 20%–25% nitric acid by mass) leh vanadium pentoxide chu nasa takin stirring hnuaiah dah a ni. Oxidation hi 50–70 °C leh 1.3–4.0 kPa ah an ti thin. A thil siam chu a lum a, a crystallized a, filter a ni a, oxalic acid thianghlimna 99.9% leh yield 90% aia tam a ni. Hetiang method hi process condition pathum hnuaiah tih theih a ni a, chungte chu atmospheric pressure, reduced pressure, leh increased pressure te an ni. Process awlsam tak a nei a, oxalic acid yield sang tak a nei a, product quality tha tak a nei a, nitric acid pawh a recovery vek tawh mai mai a, mahse raw material man a sang hle.

Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate – Industrial Grade 99.6% Thianghlim
Kum 2006 atang khan chemical siamtu leh exporter rintlak tak Shandong Pulisi Chemical Co., Ltd. hian quality control khauh tak nen high-purity oxalic acid dihydrate (H2C2O4·2H2O, CAS 6153-56-6, EINECS 205-634-3) siamchhuah kawngah a thiam hle a ni. Kan industrial-grade oxalic acid hian a thianghlimna tlem ber 99.6% a nei a, bawlhhlawh level hniam (sulfate ≤0.1%, heavy metals ≤0.002%, iron ≤0.003%) nei white crystalline powder angin a lang. Textile printing & dyeing, savun processing, metal surface tihfai, marble polishing, tui tihfai, rare earth extraction, leh pharmaceutical intermediate synthesis-ah te hman a ni nasa hle.
Kan Shandong warehouse-ah hian in-stock inventory lian tak tak kan nei a, bulk order-te chu thawn nghal theih a ni. Flexible packaging options (25kg, 50kg, 1000kg bags) leh Qingdao, Tianjin, emaw Shanghai port atanga khawvel pum huapa thawn chhuah te hian khawvel pumah a hun taka thawn chhuah theihna a siam a ni. Industrial mamawh hrang hrang phuhruk nan technical support kimchang, COA/MSDS documentation, leh competitive pricing kan pe a ni.
Vawiin hian min rawn biak la, customized quote leh i oxalic acid supply chain chu secure rawh.
