Ethylene Glycol Nitric Acid Oxidation Method na Oxalic Acid
Sayan proseso na oksidasyon et mipara ed paraan na oksidasyon na starch. Say aqueous ethylene glycol solution et painitan ed 60 °C, tan say nanlaok ya asido (30%-40% sulfuric acid ed masa, 20%-25% nitric acid ed belat) tan vanadium pentoxide et iyarum ed mabiskeg ya panag-stir. Say oxidation et nagagawa ed 50-70 °C tan 1.3-4.0 kPa. Say produkto et palemewen, nakristal, tan nasalatan pian naala so oxalic acid ya walay puro ton 99.9% tan say ani et masulok ya 90%. Sayan paraan et nayarin gawaen ed taloran kondisyon na proseso: presyon na atmospera, abawasan a presyon, tan inmatagey a presyon. Simpli so proseso to, atagey so oxalic acid yield, maong so kalidad na produkto, tan ngalngalin sigpot ya nabawi so nitric acid, balet atagey so presyo na raw material.

Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate – Industrial Grade 99.6% Purity
Say Shandong Pulisi Chemical Co., Ltd., sakey a napanmatalkan a manggagawa tan managlako na kemikal manlapu nen 2006, et man-espesyalisar ed panaggawa na high-purity oxalic acid dihydrate (H2C2O₄·2H2O, CAS 6153-56-6, EINECS 2053-43) ya walaan na estrikton kontrol. Say industrial-grade ya oxalic acid mi et walaan na sankaabebaan ya 99.6% ya kalinisan, ya singa amputin kristal ya pulbos ya abeba so karutakan to (sulfate ≤0.1%, heavy metals ≤0.002%, iron ≤0.003%). Saya so malaknab ya uusaren ed panag-imprinta tan panagtina na tela, panagproseso na katat, panaglinis na tapew na metal, panagpakintab na marmol, panagtambal na danum, panag-ala na rare earth, tan panaggawa na tambal.
Mansiasiansia kami na baleg ya in-stock ya imbentaryo ed bodega mi ed Shandong, ya mamapawala na tampol ya pangipapawit na dakel ya order. Saray nababalang ya opsyon ed panagbalot (25kg, 50kg, 1000kg ya bag) tan say global shipping manlapud Qingdao, Tianjin, odino Shanghai ports so mamaseguro na suston pangiter ed interon mundo. Mangiiter kami na kompleton teknikal a suporta, dokumentasyon na COA/MSDS, tan kompetitibon presyo pian nasumpal so nanduruman pankaukolan na industriya.
Kontakin kami natan parad sakey a presyo tan naseguro so suplay na oxalic acid yo.
