Indlela Yekuhlanganisa I-Oxalic Acid Ikhabhoni Monoxide
Lendlela ekucaleni yasebentisa iPalladium kanye neluswayi lwelitfusi njengetintfo letikhutsatako, futsi yenta kuhlanganiswa kwesigaba-semanti se carbon monoxide, umoya-mpilo, tjwala, kanye ne nitric acid lencane ku 8–11 MPa kanye na 90–100 °C. Lokuphendvula kucala kukhicita i-oxalate ester, lese iyahlanganiswa ngemanti ngaphansi kwetimo tekushisa kwentela kwakha i-oxalic acid kanye netjwala lobuhambisanako.
Lendlela inendlela yinye ye catalyst, umsebenti lophakeme, kukhetsa lokuhle, kululama lokulula, kuhlanteka lokusetulu kwemkhicito, kanye nekungcola lokuphansi kwekukhicita. Nomakunjalo, inetidzingo letisetulu tekuhlanteka kwe carbon monoxide, kusetjentiswa lokusetulu, ema catalysts labita kakhulu, kanye nekutjala imali lesetulu.
Kusebentisa iPd/C njengentfo lekhutsatako, icarbon monoxide kanye ne nitrite ester kuhlanganiswa kwentela kuhlanganisa ioxalate ester ku 130 °C kanye nekucindzeteleka kwemoya, nge nitric oxide njengemkhicito longaphansi. i-oxalic acid kanye netjwala lobuhambisanako kutfolakala ngekutsi kuhlanganiswe i-oxalate ester. Lesixazululo se tjwala lesehlukanisiwe siyaphindze sibe ne oxidation kwenta i nitrite ester, lengaphindze isetjentiswe.
Sikhungo seFujian sesakhiwo setintfo, i-Academy of Sciences yaseShayina, yente lucwaningo ngesilinganiso setintfo letiluhlata kanye netimo letehlukene tekushesha kwesikhala ngekuhlanganiswa kwe-catalytic kwe-dimethyl oxalate elucwaningweni le-catalysts yekucindzeteleka kwemoya lokuhlanganiswa kwe-CO kuya ku-oxalic acid, kanye. Le Pd (2.0%)/α-Al2O3 lephucukile ifinyelele umkhicito wesikhatsi-semkhatsi we 999 g/L·h ngaphansi kwetimo tekucindzeteleka kwemkhatsi, 140 °C, CO/CH3ONO=1.5, kanye nekushesha kwemkhatsi we 3000/h. Lesikhungo sabambisana neSikhungo Sekuklama Emakhemikhali Ephethroli saseFujian kanye neSitjalo se-Ammonia saseFujian Nanqing kwenta luhlolo lwekulinga lwe-100 t/a lwekubuyisa i-CO kusuka ekukhuhleni kwelitfusi le-ammonia leyentiwe, kuhlanganiswa kwe-dimethyl oxalate ngekucindzetelwa kwemoya, kanye nekuhlanganiswa kwe-hydroxa acid kuya ku-hydroxa.
Nawucatsanisa nendlela ye liquid-phase, lendlela inekukhetsa lokusetulu, inchubo lelula, kuhlanteka lokusetulu kwemkhicito, kanye netindleko letiphansi tekukhicita. Ingasebentisa igesi yemvelo noma emalahle njengetintfo letiluhlata, futsi ingaphindze isebentise icarbon monoxide letfolakala ngekukhuhla i-ammonia copper noma sithando se phosphorus lephuti, sithando sekubhubhisa, kanye negesi yemsila wekugucula njengemtfombo wegesi ye carbon monoxide. Ngesikhatsi lesifanako, inganiketa tintfo letishibhile letiluhlata tekukhicita i-ethylene glycol kanye nekuhlanganiswa lokuhlangene ne-oxalate ester njengentfo lesemkhatsini.

Inkampani Yemakhemikhali YaseShandong Pulisi, Ltd. Umhlinzeki We-Oxalic Acid Lesetulu
Yasungulwa nga 2006, iPulisi Chemical ikhetsekile ku oxalic acid lesetulu lehlantekile (CAS 144-62-7) lehambisana nemazinga emhlaba wonkhe ekutfumela ngaphandle kwawo womabili emabanga etimboni kanye nalacolisiwe. Sikhungo setfu sekukhicita lesisekelwe ku Zibo sicinisekisa kulawula lizinga lelicinile, nge oxalic acid yesigaba setimboni letigabatisa ngekuhlanteka lokungenani kwa 96% kanye nelizinga lelicolisiwe lelifinyelela ku 99.6% wekuhlanteka-lehlangabetana netidzingo letehlukahlukene tetimboni.
I-oxalic acid yetfu igcamile ngekuncibilika kwayo lokuhle kakhulu kanye netimphahla temakhemikhali leticinile, isebenta njengentfo leluhlata legucugucukako kuyoyonkhe imikhakha. Ekucubunguleni tinsimbi, isusa kahle umgcobo kanye netinhlayiya te-oxide letisetulu kusuka ensimbini, i-aluminium, kanye nelitfusi, kwenta ncono kunamatsela kwekugcobisa kwetimoto, i-aerospace, kanye neticelo te-electroplating. Etindvwangu, isebenta njengendlela yekuhlanta lehambisana nemvelo kanye nekulungisa idayi, kwenta ncono kucina kwembala wendvwangu kanye nekukhanya.
Ngekwengeta, isetjentiswa kakhulu ekuhlanganiseni imitsi, kucubungula tigodvo, kukhipha tinsimbi letingakavami, kanye nekuhlanta sikali semanti. Sicinisekisiwe nge-ISO 9001 kanye ne-EU REACH, siniketa emaphakethe lasemgangatfweni langu-25kg ema-oda lamanyenti, sicinisekisa kuniketa lokutsembekile emhlabeni wonkhe. Noma ngabe kukhicita ngesilinganiso lesikhulu setimboni noma kusetjentiswa lokusezingeni lelisetulu, iPulisi Chemical iletsa lizinga lelifanako kanye nekwesekelwa kwebungcweti.
