Nzira yekubatanidza Oxalic Acid Carbon Monoxide
Pakutanga nzira iyi yaishandisa palladium ne copper salts se catalysts, uye yakaita liquid-phase coupling reaction ye carbon monoxide, oxygen, alcohol, uye dilute nitric acid pa 8–11 MPa uye 90–100 °C. Mhinduro iyi inotanga yagadzira oxalate ester, iyo inozonyudzwa mumvura inopisa kuti igadzire oxalic acid ne alcohol inoenderana nayo.
Nzira iyi ine sisitimu imwe chete ye catalyst, inoshanda zvakanyanya, inosarudza zvakanaka, iri nyore kudzoreredza, kuchena kwezvigadzirwa zvakawanda, uye kusvibiswa kushoma kwekugadzirwa. Zvisinei, ine zvinodiwa zvakanyanya zvekuchena kwecarbon monoxide, kushandiswa kwakanyanya, catalysts dzinodhura, uye mari yakawanda yekudyara.
Uchishandisa Pd/C sechinhu chinobatsira pakugadzira, carbon monoxide ne nitrite ester zvinosanganiswa kuti zvigadzire oxalate ester pa 130 °C uye mhepo inomanikidza, pamwe ne nitric oxide sechinhu chinobva pairi. Oxalic acid ne alcohol inoenderana nayo zvinowanikwa nekushandisa hydrolyzing ye oxalate ester. Mushonga we alcohol wakaparadzaniswa unoiswazve mu oxidization kuti ugadzire nitrite ester, iyo inogona kudzokororwa.
Fujian Institute of Structure of Matter, Chinese Academy of Sciences, yakaita tsvakiridzo pamusoro pehuwandu hwezvinhu zvakagadziriswa uye mamiriro akasiyana-siyana ekumhanya kwemuchadenga pakugadzira dimethyl oxalate catalytic mukutsvaga macatalysts ekubatanidza CO2 ne oxalic acid mumhepo, uye yakasarudza mamiriro akakodzera ekuita. Pd (2.0%)/α-Al₂O₃ catalyst yakagadziridzwa yakawana goho repanzvimbo-nguva re999 g/L·h pasi pemamiriro ekumanikidzwa kwemuchadenga, 140 °C, CO/CH₃ONO=1.5, uye kumhanya kwemuchadenga kwe3000/h. Sangano iri rakabatana neFujian Petrochemical Design Institute neFujian Nanqing Ammonia Plant kuti vaite bvunzo ye100 t/a pilot yekudzosa CO2 kubva mukukwesha mhangura yakagadzirwa neammonia, kugadzira dimethyl oxalate mumhepo catalytic, uye hydrolysis kune oxalic acid.
Kana tichienzanisa nenzira ye liquid-phase, nzira iyi ine sarudzo yepamusoro, nzira iri nyore, kuchena kwezvigadzirwa, uye mutengo wakaderera wekugadzira. Inogona kushandisa gasi rechisikigo kana marasha sezvinhu zvekugadzira, uye inogona zvakare kushandisa carbon monoxide yakawanikwa kubva kuammonia copper scrubbing kana yellow phosphorus furnace, blast furnace, uye converter tail gas senzvimbo yegasi re carbon monoxide. Panguva imwe chete, inogona kupa zvinhu zvakachipa zvekugadzira ethylene glycol uye synthesis yakabatana ne oxalate ester senzira yepakati.

Shandong Pulisi Chemical Co., Ltd. | Mupi wePremium Oxalic Acid
Yakavambwa muna 2006, Pulisi Chemical inonyanya kugadzira oxalic acid (CAS 144-62-7) inotevedzera mitemo yepasi rose yekutengeserana kunze kwenyika yemhando dzemaindasitiri neyemhando dzakagadziriswa. Nzvimbo yedu yekugadzira iri muZibo inovimbisa kudzora mhando zvakanyanya, ine oxalic acid yemhando yeindasitiri ine hutsanana hwe96% uye 99.6% - ichizadzisa zvinodiwa zvakasiyana-siyana zvemaindasitiri.
Oxalic acid yedu inoonekwa nekunyungudika kwayo kwakanaka uye hunhu hwayo hwemakemikari hwakagadzikana, inoshanda sechinhu chinoshandiswa zvakasiyana-siyana muzvikamu zvakasiyana. Mukugadzirisa simbi, inobvisa ngura uye zvidimbu zve oxide pamusoro pesimbi, aruminiyamu, nemhangura zvinobudirira, ichivandudza kunamira kwe coating kune mota, aerospace, uye electroplating applications. Mumachira, inoshanda se bleaching agent inochengetedza nharaunda uye inogadzirisa dhayi, ichivandudza kukurumidza kwemavara emucheka uye kupenya kwawo.
Pamusoro pezvo, inoshandiswa zvakanyanya mukugadzira mishonga, kugadzira matanda, kuburitsa simbi yerare earth, uye kugadzirisa mvura. Yakasimbiswa neISO 9001 neEU REACH, tinopa mapurasitiki akajairwa e25kg ekuodha akawanda, tichivimbisa kuwanikwa kwakavimbika pasi rose. Ingave yekugadzira maindasitiri makuru kana mashandisirwo emhando yepamusoro, Pulisi Chemical inopa rutsigiro rwemhando yepamusoro uye rwehunyanzvi nguva dzose.
