Mafunso Ofunsidwa Kawirikawiri

Mukufuna thandizo? Onetsetsani kuti mwapita ku malo athu othandizira kuti mupeze mayankho a mafunso anu!

Kodi tingasindikize chizindikiro chathu pa chinthucho?

Inde, tikhoza kuchita. Ingotitumizirani kapangidwe ka logo yanu.

Kodi mumalandira maoda ang'onoang'ono?

Inde. Ngati ndinu wogulitsa pang'ono kapena bizinesi yoyambira, ndife okonzeka kukula nanu. Ndipo tikuyembekezera kugwira nanu ntchito limodzi kwa nthawi yayitali.

Nanga mtengo wake ndi wotani? Kodi mungaupange kukhala wotsika mtengo?

Nthawi zonse timaona ubwino wa kasitomala kukhala chinthu chofunika kwambiri. Mtengo ungathe kukambidwa pazifukwa zosiyanasiyana, tikukutsimikizirani kuti mupeza mtengo wopikisana kwambiri.

Kodi mumapereka zitsanzo zaulere?

Ndife okondwa kuti mutha kutilembera ndemanga zabwino ngati mumakonda zinthu ndi ntchito zathu, tidzakupatsani zitsanzo zaulere pa oda yanu yotsatira.

Kodi mumatha kupereka zinthu pa nthawi yake?

Zachidziwikire! Takhala akatswiri pa mzerewu kwa zaka zambiri, makasitomala ambiri amapanga mgwirizano ndi ine chifukwa timatha kutumiza katunduyo pa nthawi yake ndikusunga katunduyo ali wabwino kwambiri!

Kodi ndingapite ku kampani yanu ndi fakitale yanu ku China?

Inde. Mwalandiridwa kwambiri kuti mudzacheze kampani yathu ku Zibo, China. (1.5hr kuchokera ku Jinan)

Kodi ndingayitanitse bwanji oda?

Mungotumiza mafunso kwa aliyense wa ogulitsa athu kuti mudziwe zambiri zokhudza oda, ndipo tidzafotokoza njira yotsatirira. (2) Njira Yolumikizira Gas-phase ya Oxalic Acid
Anafufuza ndikupanga njira yolumikizira mpweya wa carbon monoxide pogwiritsa ntchito njira ya madzi. Pogwiritsa ntchito Pd/C ngati chothandizira, pa 130 °C ndi kupanikizika kwa mpweya, carbon monoxide imalumikizidwa ndi alkyl nitrite kuti ipange oxalate, ndi nitric oxide ngati chinthu china. Oxalic acid ndi mowa zimapezeka mwa hydrolysis ya oxalate:2CO+2RONO=(COOR) 2+2NO
(COOR) 2+2H 2O=2ROH+C 2H 2O 4
Pambuyo polekanitsa oxalic acid, yankho la mowa limasanduka alkyl nitrite kudzera mu njira yotsatirayi yobwezeretsanso:
4NO+4ROH+O 2=4RONO+2H 2O
Njirayi ili ndi kusankha kwakukulu kwambiri, yokhala ndi zokolola za 97%–98%, zinthu zopangira zomwe zimapezeka mosavuta, njira yosavuta, kupanga kosalekeza, komanso kuyera kwambiri kwa zinthu. Sikuti imangokhala ndi ndalama zochepa zopangira komanso ingapereke zinthu zopangira zotsika mtengo kwa makampani opanga omwe amagwiritsa ntchito ethylene glycol ndi oxalate ngati zinthu zapakati. Zanenedwa kuti mu Meyi 2010, Inner Mongolia Tongliao Jinmei Chemical Co., Ltd. yaku China idayambitsa bwino chomera choyamba padziko lonse cha 100,000 t/a coal-to-oxalic acid, chomwe choyamba chimagwiritsa ntchito gasification ya malasha kuti apange CO kenako ndikukonza oxalic acid.
