Ethylene Glycol Nitric Acid Oxidation Method me Oxalic Acid
Kit me loko jami ni rom ki kit me loko jami ma ki lwongo ni starch. Gin ma ki lwongo ni aqueous ethylene glycol solution ki lyeto nio wa i 60 °C, ki ki medo acid ma ki rubu (30%–40% sulfuric acid ki pek ne, 20%–25% nitric acid ki pek ne) ki vanadium pentoxide ki medo i te buru matek. Oxidation ni ki tiimo i 50-70 °C ki 1.3-4.0 kPa. Gin ma ki yubu ni ki juku, ki loko, ki ki yubu me nongo oxalic acid ma leng ne tye 99.9% ki rwom ma kato 90%. Yoo me tic ni ki twero tiimo ne i te jami adek: rwom me yamo, rwom ma piny, ki rwom ma malo. Tye ki yoo ma yot, kelo oxalic acid madwong, jami ma ki yubu maber, ki dwoko nitric acid cen, ento wel jami ma ki tiyo kwede ni tye malo.

Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate – rwom ma lamal 99.6%
Shandong Pulisi Chemical Co., Ltd., ma ki genne i yubu ki cwalo jami i lobo mukene cake i mwaka 2006, tye ki ngec me yubu oxalic acid dihydrate (H2C2O4·2H2O, CAS 6153-56-6, EINECS 2053-63) ki rwom ma lamal. Gin ma ki lwongo ni industrial-grade oxalic acid ni tye ki ler ma romo 99.6%, ma nen calo buru ma nen calo buru ma nen calo ler ma nen maber (sulfate ≤0.1%, heavy metals ≤0.002%, iron ≤0.003%). Ki tiiyo kwede i yubu bongo ki keto rangi, yubu del ler, lwoko kom jami ma ki yubu ki nyonyo, yubu got ma ki lwongo ni marble, yubu pii, kwanyo jami ma pe nen, ki yubu jami ma ki tiyo kwede me cango two.
Wa gwoko jami mapol ma tye i ot gwoko jami wa i Shandong, ma miyo wa twero cwalo jami mapol oyotoyot. Kit me keto jami ma twero loko (25kg, 50kg, 1000kg bags) ki cwalo jami i wilobo weny ki i Qingdao, Tianjin, onyo Shanghai ports miyo cwalo ne i kare ma opore i wilobo weny. Wan wa miiyo kony me tic ma oromo, coc me COA/MSDS, ki wel ma opore me cobo miti pa dano ma pat pat.
Lok kwedwa tin pi wel ma ki yubu piri keni ki gwoko yoo me cato oxalic acid ni.
