Kugwiritsa ntchito
Ubwino umodzi waukulu wa DMC ndi kuthekera kwake kusintha phosgene ngati wothandizira carbonylating, kupereka njira yotetezeka komanso yosamalira zachilengedwe. Phosgene imakhala pachiwopsezo chachikulu ku thanzi la anthu komanso zachilengedwe chifukwa cha kawopsedwe kake. Pogwiritsa ntchito DMC m'malo mwa phosgene, opanga sangangowonjezera chitetezo, komanso amathandizira kupanga njira yobiriwira, yoyeretsa.
Kuphatikiza apo, DMC imatha kukhala m'malo mwa methylating agent dimethyl sulfate. Dimethyl sulfate ndi mankhwala oopsa kwambiri omwe amawononga kwambiri ogwira ntchito komanso chilengedwe. Kugwiritsira ntchito DMC monga wothandizira methylating kumathetsa ngozizi pamene kumapereka zotsatira zofanana. Izi zimapangitsa DMC kukhala yabwino kwa mafakitale opanga mankhwala, agrochemicals, ndi mankhwala ena ofunikira a methyl.
Kuphatikiza pa zabwino zomwe tatchulazi, DMC imachitanso bwino ngati chosungunulira kawopsedwe chochepa, ndikupangitsa kuti ikhale chisankho chowoneka bwino pamagwiritsidwe osiyanasiyana. Kuchepa kwake kawopsedwe kumatsimikizira malo otetezeka ogwira ntchito, kuchepetsa chiopsezo cha ogwira ntchito ndi ogula kuzinthu zoopsa. Kuphatikiza apo, kusungunuka kwabwino kwa DMC komanso kuyanjana kwakukulu ndi zida zosiyanasiyana kumapangitsa kuti ikhale yofunika kwambiri popanga zopangira mafuta. Kugwiritsa ntchito DMC ngati zosungunulira zowonjezera mafuta kumathandizira kuyaka bwino kwa petulo, komwe kumachepetsa mpweya komanso kumapangitsa kuti injini igwire bwino ntchito.
Pomaliza, dimethyl carbonate (DMC) ndi njira yosunthika komanso yosasunthika kumagulu azikhalidwe. Chitetezo chake, kusavuta, kawopsedwe kochepa komanso kuyanjana kumapangitsa DMC kukhala yabwino pazogwiritsa ntchito zosiyanasiyana. Posintha phosgene ndi dimethyl sulfate, DMC imapereka njira yotetezeka, yobiriwira popanda kusokoneza magwiridwe antchito. Kaya imagwiritsidwa ntchito ngati carbonylating agent, methylating agent, kapena low-toxicity solvent, DMC ndi njira yodalirika yamafakitale omwe akufuna kupititsa patsogolo malonda ndi njira ndikuchepetsa kuwononga chilengedwe.
