Ethylene Glycol Nitric Acid Oxidation Ɔkwan a wɔfa so yɛ Oxalic Acid
Saa oxidation kwan yi te sɛ starch oxidation kwan no ara pɛ. Wɔde ethylene glycol aduru a nsu wom yɛ hyew kodu 60 °C, na wɔde acid a wɔadi afra (30%–40% sulphuric acid wɔ ne kɛse mu, 20%–25% nitric acid wɔ ne kɛse mu) ne vanadium pentoxide ka ho wɔ ahoɔden a wɔde kankan no mu. Wɔyɛ oxidation no wɔ 50–70 °C ne 1.3–4.0 kPa. Wɔma aduru no yɛ nwini, ɛyɛ ahwehwɛ, na wɔyiyi mu ma wonya oxalic acid a ɛho tew 99.9% na aba boro 90%.
