Sharaxaad:
Dimethyl carbonate wuxuu u muuqdaa dareere cad oo aan midab lahayn oo leh ur macaan. Ka cufan biyaha oo xoogaa ku milma biyaha. Uumiga ayaa ka culus hawada. Waxaa loo isticmaalaa in lagu sameeyo kiimikooyin kale iyo dareere ujeedo gaar ah leh.

Isticmaalka
Dimethyl carbonate waxaa loo isticmaalaa sidii dareere ku jira isku-darka dabiiciga ah waxaana loo arkaa inuu yahay beddelka dareeraha sida methyl ethyl ketone, tert-butyl acetate iyo parachlorobenzotrifluoride. Waxay ku lug leedahay dhexdhexaadinta diyaarinta diphenylcarbonate, kaas oo isna loo isticmaalo sidii walxo cayriin oo muhiim ah oo loogu talagalay isku-darka Bisphenol-A-polycarbonate. Waxa kale oo loo isticmaalaa sidii wakiil methylating 'cagaar' ah oo ku lug leh methylation-ka aniline, phenols iyo carboxylic acids. Waxaa loo isticmaali karaa sidii wax lagu daro shidaalka sababtoo ah waxa ku jira oksijiin badan. Waxa kale oo ay heshaa codsiyada la xiriira supercapacitors iyo baytariyada lithium.
Beddelka deegaanka ee dimethyl sulfate, qv, iyo methyl halides ee falcelinta methylation iyo phosgene, qv, ee falcelinta methylcarbonylation.
