Ethylene Glycol Nitric Acid Oxidation Method ning Oxalic Acid
Ing prosesu ning oxidation kalupa ne ning paralan ning starch oxidation. Ing aqueous ethylene glycol solution papainit ya anggang 60 °C, at ing mixed acid (30%–40% sulfuric acid by mass, 20%–25% nitric acid by mass) ampo ing vanadium pentoxide iyabe la keng masikan a pamag-stir. Ing oxidation gagawan de keng 50-70 °C ampo 1.3-4.0 kPa. Ing produktu mipalamig ya, mi-crystallize ya, at mi-filter ya para mika oxalic acid a maki purity a 99.9% ampo ing yield a maigit 90%. Ing paralan ayni malyari yang gawan keng atlung kundisyun ning prosesu: atmospheric pressure, mabawas a pressure, ampo matas a pressure. Atin yang simpleng prosesu, matas a oxalic acid yield, masanting a kalidad ning produktu, ampo halus ganap a pamagbawi ning nitric acid, pero matas ya ing presyu ning raw material.

Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate – Industrial Grade 99.6% Purity
Shandong Pulisi Chemical Co., Ltd., metung yang kapanaligan a gagawang kemikal ampo exporter manibat 2006, magspecialize ya keng pamaglalang high-purity oxalic acid dihydrate (H2C2O4·2H2O, CAS 6153-56-6, EINECS 2053-43) a maki mahigpit a kalidad. Ing kekaming industrial-grade oxalic acid atin yang minimum a purity a 99.6%, lulual ya bilang maputing crystalline powder a maki mababang impurity levels (sulfate ≤0.1%, heavy metals ≤0.002%, iron ≤0.003%). Maralas yang magagamit keng pamag-imprinta ampo pamagtina ning tela, pamagprosesu keng balat, pamaglinis keng metal, pamag-polish keng marmol, pamag-treat keng danum, pamag-extract keng rare earth, ampo ing pharmaceutical intermediate synthesis.
