Oxalic Acid Carbon Monoxide Pehtlaihnak Lam
Hi lam nih hin a hramthawk ahcun palladium le dar chiti kha thlennak ah a hman, cun 8-11 MPa le 90-100 °C ah carbon monoxide, oxygen, zu, le a tlawmmi nitric acid hna i ti-phase pehtlaihnak a tuah. Cu thil cangmi nih cun oxalate ester a chuahter hmasa, cu cu lumternak dirhmun tangah oxalic acid le aa pehtlaimi zu a chuahtertu ah a cawh.
Hi lam nih hin catalyst system pakhat lawng a ngei, cawlcanghnak sang, thim khawhnak ttha, fawi tein hmuh tthannak, thilri thianhlimnak sang, le chuahmi thurhnawmhnak tlawm. Sihmanhsehlaw, carbon monoxide thianhlimnak, hmannak a tam, a man a fakmi catalysts, le tangka hmannak a sangmi caah a herhmi a sang.
Pd/C kha catalyst ah hman in, carbon monoxide le nitrite ester cu 130 °C le thli hneknak ah oxalate ester ser awkah an i fonh, nitric oxide cu a chuakmi thil pakhat a si. Oxalic acid le aa pehtlaimi zu cu oxalate ester kha hydrolyze tuahnak in hmuh khawh a si. A tthenmi zu cawhmi cu nitrite ester ser awkah a tthawnter tthan, cucu hman tthan khawh a si.
Fujian Institute of Structure of Matter, Chinese Academy of Sciences nih CO le oxalic acid thli hneknak catalytic coupling caah catalysts hlathlainak ah dimethyl oxalate catalytic synthesis cung ah raw materials le vancung rangnak thil sining phunphun kongah hlathlainak an tuah. A tthanchomi Pd (2.0%)/α-Al2O3 catalyst nih thli hneknak, 140 °C, CO/CH3ONO=1.5, le 3000/h vancung rangnak dirhmun tangah 999 g/L·h caan-caan chuah khawhnak a hmuh. Institute nih Fujian Petrochemical Design Institute le Fujian Nanqing Ammonia Plant he 100 t/a hneksaknak hneksaknak an tuah i synthetic ammonia copper scrubbing in CO hmuh tthannak, thli hneknak in dimethyl oxalate sernak, le oxalic acid ah thlennak an tuah.
Liquid-phase phunglam he tahchunh ahcun, hi phunglam nih hin thim khawhnak a sang, a sawhsawh mi thil tuah ning, thilri thianhlimnak sang, le chuah man a tlawm. Thilri ah sermi gas asiloah lungmeihol kha a hman khawh, cun ammonia dar hnawhnak in hmuhmi carbon monoxide asiloah yellow phosphorus meiphu, puahkehnak, le converter tail gas zong kha carbon monoxide gas hrampi ah a hman khawh. Cu lio caan te ah cun, ethylene glycol chuahnak caah a man fawimi thilri a pek khawh i oxalate ester he aa fonhmi sernak caah a si.

Shandong Pulisi Chemical Co., Ltd. | A ttha bikmi Oxalic Acid Petu
2006 ah dirhmi, Pulisi Chemical cu a thiangmi oxalic acid (CAS 144-62-7) ah a thiammi a si i, cu cu ramkip kuatnak phunglam he aa tlakmi a si i, cu cu riantuannak le a thianghlimmi phun pahnih caah a si. Kan Zibo-based thilchuaknak hmun nih fek tein tthatnak uknak a tuah, riantuannak-tluk oxalic acid cu a tlawmbik 96% thiannak a ngei i a thianghlimmi-tluk in 99.6% thianhlimnak a phan—riantuannak lei herhmi phunphun a tlinh.
Kan oxalic acid cu a ttha tukmi a cawh khawhnak le a fekmi chemical sining hna ruangah a lang, sector kip ah hman khawhmi thilri ah a hman. Thir sernak ah, thir, aluminium le dar chungin vutcam le a cunglei oxide tthen pawl kha ttha tein a hloh hna, mawtaw, vanlawng le electroplating hmannak caah hnahnawhnak a tthanchoter. Thilpuan ah, pawngkam he aa remmi rangternak thilri le rong thlennak ah rian a ttuan, puan rong a fekmi le a ceunak a tthanter.
Cun, sii sernak, thing sernak, rare earth thir chuahnak le ti tlawmpal thlopnak ah tampi hman a si. ISO 9001 le EU REACH he fehtermi, a tammi order caah 25kg ttha tein chiahmi thilri kan pek hna, cu nih cun vawleicung pumpi ah zumhawktlak tein pek khawhnak a kan pek. A nganmi riantuannak caah siseh, a sangmi hmannak caah siseh, Pulisi Chemical nih aa khatmi tthatnak le thiamsang bawmhnak a pek.
