Singakwazi yini ukuphrinta ilogo yethu kumkhiqizo?

Vele, singakwenza. Vele usithumelele umklamo welogo yakho.

Uyawamukela yini ama-oda amancane?

Yebo. Uma ungumthengisi omncane noma uqala ibhizinisi, sizimisele ngempela ukukhula nawe. Futhi silangazelela ukusebenzisana nawe ukuze sibe nobudlelwano besikhathi eside.

Kuthiwani ngentengo? Ungakwazi yini ukuyenza ishibhile?

Sihlala sithatha inzuzo yekhasimende njengento eza kuqala. Intengo ingaxoxiswana ngaphansi kwezimo ezahlukene, siyakuqinisekisa ukuthi uzothola intengo encintisana kakhulu.

Ingabe ninikeza amasampula amahhala?

Kuyaziswa ukuthi ungasibhalela izibuyekezo ezinhle uma uthanda imikhiqizo nensizakalo yethu, sizokunikeza amasampula wamahhala ku-oda lakho elilandelayo.

Uyakwazi ukuletha ngesikhathi?

Vele! Sikhetheke kakhulu kulo mugqa iminyaka eminingi, amakhasimende amaningi enza isivumelwano nami ngoba singakwazi ukuletha izimpahla ngesikhathi futhi sigcine izimpahla zisezingeni eliphezulu!

Ngingavakashela inkampani yakho kanye nefektri eShayina?

Yebo. Wamukelekile kakhulu ukuvakashela inkampani yethu eZibo, eShayina. (Ibanga eliyihora eli-1.5 ukusuka eJinan)

Ngingayifaka kanjani i-oda?

Ungasithumelela nje umbuzo kunoma yimuphi wabameleli bethu bezentengiso ukuze uthole ulwazi oluningiliziwe lwe-oda, futhi sizochaza inqubo yemininingwane. Indlela Yokuhlanganisa I-Oxalic acid Carbon Monoxide
Indlela Yokuhlanganisa Isigaba Soketshezi se-Oxalic Acid
Le ndlela ekuqaleni yasebenzisa i-PdCl₂–CuCl₂–CuCl njenge-catalyst ukuze yenze ukusabela kokuxhumanisa kwe-carbon monoxide, i-oxygen, kanye ne-ethanol okwenziwa yi-liquid-phase catalytic kwe-carbon monoxide, i-oxygen, kanye ne-ethanol ku-12 MPa kanye no-115 °C ukuze kukhiqizwe i-diethyl oxalate. Yasebenzisa i-Pd/C njenge-catalyst ukuze yenze ukusabela kokuxhumanisa kwe-ethanol (noma i-butanol) ne-carbon monoxide kanye ne-oxygen lapho kukhona i-alkyl nitrite ukuze kukhiqizwe i-diethyl oxalate (noma i-dibutyl oxalate). Izilinganiso zokusabela ezihambisanayo yilezi:
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
