Mibvunzo Inowanzo bvunzwa

Unoda rubatsiro here? Iva nechokwadi chekushanyira maforamu edu ekutsigira kuti uwane mhinduro dzemibvunzo yako!

Tinogona here kudhinda logo yedu pachigadzirwa?

Ehe, tinogona kuzviita. Ingotumirai dhizaini yelogo yenyu.

Munogamuchira maodha madiki here?

Ehe. Kana uri mutengesi mudiki kana kuti uri kutanga bhizinesi, tinoda kukura newe. Uye tinotarisira kushanda newe kwenguva refu.

Ko mutengo wacho wakaita sei? Unogona here kuita kuti ive yakachipa?

Tinogara tichitora rubatsiro rwemutengi sechinhu chinonyanya kukosha. Mutengo unogona kutaurwa nezvawo mumamiriro ezvinhu akasiyana, tiri kukuvimbisa kuti uchawana mutengo unokwikwidzana zvakanyanya.

Munopa mienzaniso yemahara here?

Zvinofadza kuti munogona kutinyorera wongororo dzakanaka kana muchida zvigadzirwa zvedu nebasa redu, tichakupai mimwe mienzaniso yemahara pakutenga kwenyu kunotevera.

Unokwanisa here kuendesa zvinhu nenguva?

Ehe, takaita basa iri kwemakore akawanda, vatengi vazhinji vanoita chibvumirano neni nekuti tinokwanisa kuendesa zvinhu nenguva uye kuchengetedza zvinhu zvakanaka!

Ndingashanyira kambani yenyu nefekitori kuChina here?

Ehe. Munogamuchirwa kushanyira kambani yedu muZibo, China. (Nzira yekutyaira ye1.5H kubva kuJinan)

Ndingaisa sei odha?

Munogona kungotumira mibvunzo kune chero mumiriri wedu wekutengesa kuti muwane ruzivo rwakadzama rweodha, uye isu tichatsanangura maitiro acho. Oxalic acid Carbon Monoxide Coupling Method
Nzira yekubatanidza Oxalic acid Liquid-phase
Pakutanga nzira iyi yakashandisa PdCl₂–CuCl₂–CuCl sechinokonzeresa kuita liquid-phase catalytic coupling reaction yecarbon monoxide, oxygen, uye ethanol pa12 MPa uye 115 °C kugadzira diethyl oxalate. Yakashandisa Pd/C sechinokonzeresa kuita coupling reaction yeethanol (kana butanol) necarbon monoxide neoxygen pamberi pealkyl nitrite kugadzira diethyl oxalate (kana dibutyl oxalate). Ma reaction equations anoenderana ndeaya:
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
