Oxalic Acid Carbon Monoxide Coupling Method
Yoo me tic man oyabo tic ki palladium ki copper ma calo gin ma kelo alokaloka, ki otimo tic me rwate ki carbon monoxide, oxygen, alcohol, ki dilute nitric acid i 8-11 MPa ki 90-100 °C. Lok ni mukwongo kelo oxalate ester, ma dong ki loko i te lyeto me yubu oxalic acid ki kongo ma rwate.
Yoo me tic ni tye ki gin acel ma kelo alokaloka, tic ma malo, yero maber, dwoko ne yot, leng pa jami ma ki yubu, ki balo jami ma ki yubu manok. Ento, tye ki jami mapol ma mite pi bedo maleng pa yamo ma ki lwongo ni carbon monoxide, tic kwede madwong, jami ma wel ne tek, ki cente madwong.
Nono Pd/C ma calo gin ma kelo alokaloka, carbon monoxide ki nitrite ester gi ribbe me yubu oxalate ester i 130 °C ki rwom me yamo, ki nitric oxide ma calo gin ma aa ki iye. Oxalic acid ki kongo ma rwate kwede ki nongo ki i hydrolyzing oxalate ester. Gin ma ki poko ni ki loko me yubu nitrite ester, ma ki twero tic kwede odoco.
Gang kwan me Fujian Institute of Structure of Matter, Chinese Academy of Sciences, otimo kwed i kom rwom me jami ma ki tiyo kwede ki rwom me ngwec pa yamo ma pat pat i kom kit ma dimethyl oxalate tiyo kwede i kwed i kom jami ma weko CO bedo ki oxalic acid, ki jami ma ki yero ma twero tic. Pd (2.0%)/α-Al₂O₃ ma ki medo ni okelo rwom me 999 g/L·h i te rwom me yamo, 140 °C, CO/CH₃ONO=1.5, ki rwom me 3000/h. Dul ni otiiyo kacel ki Fujian Petrochemical Design Institute ki Fujian Nanqing Ammonia Plant me timo temo 100 t/a me nongo CO ki i ammonia ma ki yubu ki copper scrubbing, atmospheric pressure catalytic synthesis me dimethyl oxalate, ki hydrolysis me doko oxalic acid.
Ka kiporo ki yoo me pii, yoo man tye ki rwom me yero ma malo, yoo ma yot, leng pa jami ma ki yubu, ki wel ma lapiny me yubu ne. Twero tic ki yamo ma ki lwongo ni natural gas onyo coal ma calo gin ma ki tiyo kwede, ki bene twero tic ki carbon monoxide ma ki nongo ki i ammonia copper scrubbing onyo yellow phosphorus furnace, blast furnace, ki converter tail gas ma calo yamo ma ki lwongo ni carbon monoxide. I kare acel, twero miiyo jami ma wel ne yot me yubu ethylene glycol ki yubu ne kacel ki oxalate ester ma calo gin ma tye i kin gii.

Shandong Pulisi Chemical Co., Ltd. | Lami Oxalic Acid maber loyo
Ki cako i mwaka 2006, Pulisi Chemical tye ki ngec i kom jami ma ki lwongo ni high-purity oxalic acid (CAS 144-62-7) ma lubu cik me cwalo jami i lobo mukene pi jami ma ki yubu ki jami ma ki yubu maber. Kabedo wa me yubu jami ma ki lwongo ni Zibo ni neno ni ki gwoko rwom me tic maber, ki oxalic acid ma ki yubu maber ma tye ki 96% maleng ki ma ki yubu ma romo 99.6% maleng-ma rwate ki jami ma mite i tic mapol.
Oxalic acid wa cung pi bedo ne maber ki jami ma twero bedo maber, ma tiyo calo gin ma ki tiyo kwede i dul ma pat pat. I yubu jami ma ki yubu ki nyonyo, en kwanyo buru ki jami ma ki lwongo ni surface oxide ki i kom nyonyo, aluminum, ki copper, ma weko coating bedo maber pi tic ki motoka, dege, ki tic ki mac. I kom bongo, en tiyo calo gin ma balo kwo pa dano ki gin ma weko rangi bedo maleng, ma weko rangi pa bongo bedo maber ki ryeny.
Medo ikom meno, ki tiyo kwede i yubu yadi, yubu bawo, kwanyo jami ma pe nen, ki yubu pii. Ki moko ki ISO 9001 ki EU REACH, wa miiyo jami ma ki keto i 25kg pi jami mapol, me neno ni wa miyo jami maber i wilobo weny. Kadi bed ni tye pi yubu jami mapol onyo tic ma rwom ne lamal, Pulisi Chemical miiyo kony maber ki ma rwom ne lamal.
