Yini lenesimo sengcondvo lesihle nalechubekako esifisweni semakhasimende, inkampani yetfu ihlala yenta ncono lizinga letfu lekutsengisa kute yenetise tifiso tebatsengisi futsi iphindze igcile ekuphepheni, kwetsembeka, tidzingo temvelo, kanye nekusungulwa kwetintfo letinsha te-China Wholesale China Mudanjiang Fengda H2c2o499. Oxalic Acid, Ibhizinisi letfu ligcina ibhizinisi lephephile nalephilile lehlanganiswe liciniso nekwetsembeka kusita ekugcineni kusebentisana kwesikhatsi lesidze nebatsengisi betfu.
Yikuphi unesimo sengcondvo lesihle nalechubekako esifisweni semakhasimende, inkampani yetfu ihlala yenta ncono lizinga lemphahla yetfu yekutsengisa kute yenetise tifiso tebatsengisi futsi iphindze igcile ekuphepheni, kwetsembeka, tidzingo temvelo, kanye nekusungulwa kwe , Ngetulu kwaloko, tonkhe tisombululo tetfu tikhicitwa nge-oda lelisetulu le-QC kanye ne-advan . imfanelo. Uma unesitsakatelo nganoma ngutiphi timphahla tetfu, ciniseka kutsi awusabi kusitsintsa. Sitawenta konkhe lokusemandleni etfu kuhlangabetana netidzingo takho.

Imibuto Levame Kubutwa

Udzinga lusito? Ciniseka kutsi uvakashela tinkhundla tetfu tekusekela kute utfole timphendvulo temibuto yakho!

Singaphrinta yini ilogo yetfu kulomkhicito ?

Kuliciniso kutsi singakhona kukwenta. Vele usitfumelele umklamo wakho welogo.

Uyawemukela yini ema-oda lamancane?

Yebo. Uma ungumtsengisi lomncane noma locala ibhizinisi,Sitimisele nakanjani kukhula nawe. Futsi silindzele kusebentisana nawe kute sibe nebudlelwane besikhatsi lesidze.

Kutsiwani ngentsengo? Ungayenta yini kutsi ishiphe?

Sihlala sitsatsa inzuzo yekhasimende njengentfo lebaluleke kakhulu. Intengo iyabonisana ngaphansi kwetimo letehlukene, siyakucinisekisa kutsi utfole intengo lencintisana kakhulu.

Uyatiniketa yini emasampula lamahhala?

Kuyabongwa kutsi ungasibhalela kubuyeketwa lokuhle uma utsandza imikhicito yetfu kanye nenkonzo, sitakuniketa emasampula lamahhala ku-oda lakho lelilandzelako.

Uyakhona yini kuletsa ngesikhatsi?

Yebo!sikhetsekile kulomugca iminyaka leminyenti,emakhasimende lamanyenti enta sivumelwano nami ngoba singaletsa timphahla ngesikhatsi futsi sigcine timphahla tisezingeni lelisetulu!

Ngingavakashela yini inkampani yakho nefemu yakho eChina?

Cinisekile. Uyamukelekile kakhulu kuvakashela inkampani yetfu eZibo, eChina. (1.5H indlela yekushayela kusuka eJinan)

Ngingafaka njani i-oda?

Ungavele usitfumele umbuto kunobe ngubani webameleli betfu bekutsengisa kute utfole lwati lolubanti lwe-oda, futsi sitawuchaza inchubo lenemininingwane.Oxalic acid Carbon Monoxide Coupling Indlela .
Indlela Yekuhlanganisa Yesigaba Se-Oxalic Acidi
Lendlela ekucaleni yasebentisa iPdCl2–CuCl2–CuCl njengesikhutsato kwenta umsebenti wekuhlanganiswa kwesigaba sekukhicita sekhabhoni monoxide, umoya-mpilo, kanye ne-ethanol ku 12 MPa na 115 °C kwenta i-diethyl oxalate. yamukele iPd/C njengesikhutsati sekwenta umsebenti wekuhlanganisa i-ethanol (noma i-butanol) nekhabhoni kanye nemoya-mpilo lapho khona kune-alkyl nitrite kwenta i-diethyl oxalate (noma i-dibutyl oxalate). Letilinganiso tekuphendvula letihambisanako nguleti:
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
