Ifite imyumvire myiza kandi ihamye ku byifuzo by'abakiriya, ikigo cyacu gihora giteza imbere ireme ry'ibicuruzwa byacu kugira ngo gihaze ibyifuzo by'abaguzi kandi kigakomeza kwibanda ku mutekano, kwizerwa, ibyifuzo by'ibidukikije, no guhanga udushya muri China Wholesale China Mudanjiang Fengda H2c2o4 99.6 Industrial Grade Dihydrate Price Ethanedioic Oxalic Acid, Ubucuruzi bwacu bukomeza ubucuruzi bufite umutekano kandi buvanze n'ukuri n'ubunyangamugayo kugira ngo bukomeze kugirana imikoranire n'abaguzi bacu igihe kirekire.
Ifite imyumvire myiza kandi ijyanye n'ibyo abakiriya bifuza, ikigo cyacu gihora kivugurura ubwiza bw'ibicuruzwa byacu kugira ngo gihaze ibyifuzo by'abaguzi kandi kikibanda ku mutekano, kwizerwa, ibyo ibidukikije bisaba, no guhanga udushya. Byongeye kandi, ibisubizo byacu byose bikorwa hakoreshejwe ibikoresho bigezweho n'amabwiriza akomeye ya QC kugira ngo bibe byiza. Niba ushishikajwe n'ibicuruzwa byacu, menya neza ko udatindiganya kutwandikira. Tuzakora uko dushoboye kose kugira ngo duhuze n'ibyo ukeneye.

Ibibazo Bikunze Kubazwa

Ukeneye ubufasha? Menya neza ko usura urubuga rwacu rw'ubufasha kugira ngo uhabwe ibisubizo by'ibibazo byawe!

Ese dushobora gucapa ikirango cyacu kuri icyo gicuruzwa?

Birumvikana ko dushobora kubikora. Twoherereze gusa igishushanyo mbonera cyawe.

Ese wemera kohereza ibintu bito?

Yego. Niba uri umucuruzi muto cyangwa utangiye ubucuruzi, twiteguye rwose gukurana nawe. Kandi twiteguye gukorana nawe mu gihe kirekire.

Bite se ku giciro? Ese ushobora kugihindura kidahenze?

Buri gihe dufata inyungu z'umukiriya nk'ikintu cy'ingenzi kurusha ibindi. Igiciro gishobora kuganirwaho mu bihe bitandukanye, turakwizeza ko uzabona igiciro gishimishije kurusha ibindi.

Mutanga ingero z'ubuntu?

Twishimiye ko watwandikira ibitekerezo byiza niba ukunda ibicuruzwa na serivisi byacu, tuzaguha ingero z'ubuntu ku giciro gikurikira.

Ese urashobora gutanga ku gihe?

Birumvikana ko twagize uruhare muri uru rutonde imyaka myinshi, abakiriya benshi bafitanye amasezerano nanjye kuko dushobora kugeza ibicuruzwa ku gihe kandi tukabigumana bifite ireme!

Ese nshobora gusura ikigo cyawe n'uruganda rwawe mu Bushinwa?

Yego rwose. Murakaza neza gusura ikigo cyacu kiri i Zibo, mu Bushinwa. (Iri ku muhanda wa saa 1.5 uvuye Jinan)

Nigute natanga commande?

Ushobora kutwoherereza ikibazo ku bahagarariye ubucuruzi bacu kugira ngo tubone amakuru arambuye ku byo twaguze, maze tuzagusobanurira uburyo bwo kubikoresha. Uburyo bwo guhuza aside karubone monoxyde na aside oxalike
Uburyo bwo guhuza aside ya oxalic mu gice cy'amazi
Ubu buryo bwabanje gukoresha PdCl₂–CuCl₂–CuCl nk'imashini ikora catalyst kugira ngo ikore reaction ya catalytic coupling ya monoxide karubone, ogisijeni, na ethanol kuri 12 MPa na 115 °C kugira ngo ikore diethyl oxalate. Bifashishije Pd/C nk'imashini ikora reaction ya ethanol (cyangwa butanol) hamwe na monoxide karubone na ogisijeni imbere ya alkyl nitrite kugira ngo ikore diethyl oxalate (cyangwa dibutyl oxalate). Ingano z'inyito zijyanye ni izi:
4CO+4C 2H 5 OH+O 2=2 (COOC 2H 5 ) 2+2H 2O
4CO+4C 4H 9 OH+O 2=2 (COOC 4 H 9) 2+2H 2O
