Ko te Dimethyl carbonate, e kiia ana ko DMC, he wai kore tae, marama marama me te haunga kino i te pāmahana rūma. Ko te kiato whanaunga (d204) he 1.0694, ko te rewa ko te 4°C, ko te 90.3°C, ko te 21.7°C (tuwhera) me te 16.7°C (katia), ko te taurangi whakakorikori (nd20) he 1.3687, he kore-paitini, he muramura. Ka taea te konatunatua ki te nuinga o nga wairewa waro katoa penei i te waipiro, te ketone, me te esters ahakoa te rahinga, he paku memeha ki te wai. Ka taea te whakamahi hei kaihoko methylating. Ka whakatauritea ki etahi atu matū methylating, penei i te methyl iodide me te dimethyl sulfate, he iti ake te paitini o te dimethyl carbonate, ka taea te whakaheke koiora.

Ko te Dimethyl carbonate (DMC) he hanganga ngota ngota (CH3O-CO-OCH3). Kei roto i tona hanganga rapoi ngota waro, methyl, methoxy me nga roopu carbonylmethoxy. Na reira, ka taea te whakamahi whanui i roto i nga tauhohenga whakahiato waro penei i te carbonylation, methylation, methoxylation me te carbonylmethylation. He tino whanui nga whakamahinga. Ko te nuinga o te waa ka whakamahia hei reagent carbonylation me te methylation, he taapiri penehīni, me te rauemi mata mo te synthesizing polycarbonate (PC). Ko te hanga nui-nui o DMC kua whakawhanakehia me te tukanga whakahiato kore-phosgene o te polycarbonate. Ko ona whakamahinga e whai ake nei:
1. Ka taea e te momo hou o te whakarewa iti-paitini te whakakapi i nga whakarewa penei i te toluene, te xylene, te ethyl acetate, te butyl acetate, te acetone, te butanone ranei i roto i nga ahumahi peita me te whakapiri. He hua matū kaakaariki pai ki te taiao.
2. He kaihoko methylating pai, he kaihoko waro, he kaihoko hydroxymethylating me te kaihoko methoxylating. Kei te whakamahia nuitia i roto i nga mara o nga antioxidants kai, nga kaihoko tiaki tipu, me etahi atu.
3. He whakakapi pai mo nga raau taero tino paitini penei i te phosgene, te dimethyl sulfate, me te methyl chloroformate.
4. Hangaia te polycarbonate, te diphenyl carbonate, te isocyanate, etc.
5. I roto i te rongoa, ka whakamahia ki te whakahiato i nga raau taero anti-infective, antipyretic me te analgesic drugs, taero huaora, me nga raau taero mo te punaha nerve pokapū.
6. I roto i nga pesticides, ka whakamahia te nuinga ki te whakaputa i te methyl isocyanate, katahi ka whakaputa etahi raau taero carbamate me nga pepeke (anisole).
7. Whakapiri penehīni, lithium pākahiko electrolytes, etc.
