Codsiga

Dimethyl Carbonate
1) Waa wakiilka methylating kaamil ah, wakiilka carbonylating, wakiilka methoxylating iyo wakiilka methylolating leh sifooyinka kiimikada firfircoon.Waxaa loo isticmaali karaa soo saarida carbonate polypropylene.
2) Daawooyinka iyo sunta cayayaanka, DMC waxaa loo isticmaali karaa soo saarida ciprofloxacin iyo carbadox.Sidoo kale waa walxo ceeriin ah oo lama huraan ah si loo soo saaro bateriga lithium electrolyte.Sababtoo ah hantideeda ugu wanaagsan ee kiimikaad iyo deegaanka, DMC waxay u dhaqmaysaa sidii dareere wanaagsan oo loogu talagalay daahan, rinji, khad iyo koollo beddeleysa benzene, xylene, ethyl acetate, butyl acetate, acetone, butanone, toluene.Waa bedel ku habboon walxaha sunta ah sida fosgene, dimethyl sulfate, iyo chloraformate methyl.
3) Dimethyl carbonate (DMC), waa nooc ka mid ah dhex dhexaadinta organic synthesis muhiim ah, qaab-dhismeedka kelli ka kooban carbonyl, methyl iyo hub, sida kooxda functional oksijiinta, uu leeyahay noocyo kala duwan oo waxqabadka falcelinta ee ammaanka wax soo saarka, ku haboon, ay isticmaalaan wasakh yar, fududahay in la qaado dhammaan sifooyinkaas.Sababtoo ah sunta hoose ee dimethyl carbonate, waa wax soo saarka kiimikada "cagaaran" ee suurtogalka ah.
