Indlela Yokuhlanganisa I-Oxalic Acid Carbon Monoxide
Le ndlela ekuqaleni yayisebenzisa usawoti we-palladium nowethusi njengezinto ezibangela uketshezi, futhi yenza ukusabela kokuhlangana kwe-carbon monoxide, i-oxygen, i-alcohol, kanye ne-nitric acid encibilikisiwe ku-8-11 MPa kanye no-90-100 °C. Ukusabela kuqala kukhiqiza i-oxalate ester, bese i-hydrolyzed ngaphansi kwezimo zokushisa ukuze yakhe i-oxalic acid kanye ne-alcohol ehambisanayo.
Le ndlela inesistimu eyodwa yokuvuselela, umsebenzi ophezulu, ukukhetha okuhle, ukululama okulula, ukuhlanzeka okuphezulu komkhiqizo, kanye nokungcola okuphansi kokukhiqiza. Kodwa-ke, inezidingo eziphezulu zokuhlanzeka kwe-carbon monoxide, ukusetshenziswa okuphezulu, ama-catalyst abizayo, kanye nokutshalwa kwezimali okuphezulu.
Kusetshenziswa i-Pd/C njenge-catalyst, i-carbon monoxide kanye ne-nitrite ester kuhlanganiswa ukuze kuhlanganiswe i-oxalate ester ku-130 °C kanye nomfutho womoya, kanye ne-nitric oxide njengomkhiqizo ophumayo. I-oxalic acid kanye notshwala obuhambisanayo kutholakala ngokufaka i-hydrolyzing i-oxalate ester. Isixazululo sotshwala esihlukanisiwe siyafakwa kabusha ukuze sakhe i-nitrite ester, engaphinde isetshenziswe.
I-Fujian Institute of Structure of Matter, i-Chinese Academy of Sciences, yenze ucwaningo ngesilinganiso sezinto zokusetshenziswa kanye nezimo ezahlukahlukene zesivinini sesikhala ekuhlanganisweni kwe-catalytic kwe-dimethyl oxalate ocwaningweni lwama-catalyst okuhlanganiswa kwe-CO2 ne-oxalic acid, futhi yakhetha izimo zokusabela ezifanele. I-catalyst ye-Pd (2.0%)/α-Al₂O₃ ethuthukisiwe ithole isivuno sesikhathi sesikhala esingu-999 g/L·h ngaphansi kwezimo zengcindezi yomoya, 140 °C, CO2/CH₃ONO=1.5, kanye nesivinini sesikhala esingu-3000/h. Lesi sikhungo sibambisene ne-Fujian Petrochemical Design Institute kanye ne-Fujian Nanqing Ammonia Plant ukwenza ukuhlolwa kwe-100 t/a kokuthola i-CO2 ekuhlafuneni ithusi le-ammonia elenziwe ngokwenziwa, ukuhlanganiswa kwe-catalytic kwengcindezi yomoya kwe-dimethyl oxalate, kanye ne-hydrolysis ku-oxalic acid.
Uma kuqhathaniswa nendlela yesigaba soketshezi, le ndlela inokukhetha okuphezulu, inqubo elula, ubumsulwa bomkhiqizo obuphezulu, kanye nezindleko eziphansi zokukhiqiza. Ingasebenzisa igesi yemvelo noma amalahle njengezinto zokusetshenziswa, futhi ingasebenzisa ne-carbon monoxide etholwe ku-ammonia copper scrubbing noma ku-yellow phosphorus furnace, ku-blast furnace, kanye ne-converter tail gas njengomthombo wegesi ye-carbon monoxide. Ngesikhathi esifanayo, ingahlinzeka ngezinto zokusetshenziswa ezishibhile zokukhiqizwa kwe-ethylene glycol kanye nokuhlanganiswa okuhlanganisiwe ne-oxalate ester njengesixhumi esiphakathi.

I-Shandong Pulisi Chemical Co., Ltd. | Umhlinzeki we-Premium Oxalic Acid
Yasungulwa ngo-2006, i-Pulisi Chemical igxile ku-oxalic acid ehlanzekile kakhulu (i-CAS 144-62-7) ehambisana nezindinganiso zamazwe ngamazwe zokuthumela kwamanye amazwe kokubili amazinga ezimboni kanye namazinga acwengisisiwe. Isikhungo sethu sokukhiqiza esisekelwe e-Zibo siqinisekisa ukulawulwa kwekhwalithi okuqinile, nge-oxalic acid esezingeni lezimboni enokuhlanzeka okungenani okungu-96% kanye nezinga elicwengisisiwe elifinyelela ku-99.6% ukuhlanzeka—ihlangabezana nezidingo zezimboni ezahlukahlukene.
I-oxalic acid yethu ivelele ngokuncibilika kwayo okuhle kakhulu kanye nezakhiwo zamakhemikhali ezizinzile, isebenza njengezinto zokusetshenziswa eziguquguqukayo kuzo zonke izigaba. Ekucubungulweni kwensimbi, isusa ngempumelelo ukugqwala kanye nezingqimba ze-oxide ebusweni bensimbi, i-aluminium, kanye nethusi, ithuthukise ukunamathela kokumboza kwezicelo zezimoto, zezindiza, kanye ne-electroplating. Ezindwangu, isebenza njenge-ejenti yokumhlophela enobungani nemvelo kanye nokulungisa udayi, ithuthukisa ukushesha kombala wendwangu nokukhanya.
Ngaphezu kwalokho, isetshenziswa kabanzi ekuhlanganisweni kwemithi, ekucubungulweni kwezinkuni, ekukhishweni kwensimbi engavamile, kanye nasekuphathweni kwezikali zamanzi. Iqinisekiswe yi-ISO 9001 kanye ne-EU REACH, sihlinzeka ngamaphakheji ajwayelekile angama-25kg ama-oda amaningi, siqinisekisa ukutholakala okuthembekile emhlabeni wonke. Kungakhathaliseki ukuthi kukhiqizwa ezimbonini ezinkulu noma kuzinhlelo zokusebenza eziphezulu, i-Pulisi Chemical inikeza ukwesekwa kwekhwalithi okuqhubekayo kanye nobungcweti.
