Mmiri Kemịkal DMC/Dimethyl Carbonate nke na-eweta ọla edo
Okwu Mmalite Ngwaahịa
Dimethyl carbonate / DMC bụ ihe dị mkpa sitere na organic nke nwere usoro kemịkalụ C3H6O3 na ibu molekul nke 90.08g/mol. Ọ bụ mmiri na-enweghị agba, nke fọrọ nke nta ka ọ ghara ịgbaze na mmiri, ma nwee nnukwu mgbaze na ihe mgbaze organic dịka ethanol, benzene na acetone. Dimethyl carbonate nwere njirimara nke obere nsí, obere mgbanwe, ezigbo ihe na-emebi emebi na ihe na-adịghị emerụ gburugburu ebe obibi, yabụ a na-eji ya eme ihe nke ukwuu na ụlọ ọrụ kemịkalụ, ọgwụ, nri na ihe ndị ọzọ.
