Ko te dimethyl carbonate, e kiia nei ko te DMC, he wai mārama, kāore he tae, he kakara kino i te pāmahana rūma. Ko tōna matotoru whanaunga (d204) ko 1.0694, ko tōna ira rewa ko 4°C, ko tōna ira kohua ko 90.3°C, ko tōna ira mura ko 21.7°C (tuwhera) me te 16.7°C (kati), ko tōna taupū whakaata (nd20) ko 1.3687, ā, he mura ngāwari, kāore hoki he paitini. Ka taea te whakaranu ki te nuinga o ngā whakarewa rauropi pērā i ngā waipiro, ngā ketone, me ngā esters i roto i tētahi ōwehenga, ā, he paku wairewa ki te wai. Ka taea te whakamahi hei kaihoko methylating. Ki te whakatauritea ki ētahi atu kaihoko methylating, pērā i te methyl iodide me te dimethyl sulfate, he iti ake te paitini o te dimethyl carbonate, ā, ka taea te pirau.

He hanganga ngota ahurei tō te Dimethyl carbonate (DMC) (CH3O-CO-OCH3). Kei roto i tōna hanganga ngota ngā rōpū carbonyl, methyl, methoxy me te carbonylmethoxy. Nō reira, ka taea te whakamahi whānui i roto i ngā tauhohenga hanga waro pēnei i te carbonylation, te methylation, te methoxylation me te carbonylmethylation. He whānuitia ngā whakamahinga. Ko te nuinga o te wā ka whakamahia hei matū carbonylation me te methylation, hei tāpiri penehīni, me te rauemi mata mō te hanga polycarbonate (PC). Kua whanake haere te hanga nui o te DMC me te tukanga hanga kore-phosgene o te polycarbonate. Ko ōna whakamahinga e whai ake nei:
1. Ka taea e tētahi momo whakarewa iti-paitini hou te whakakapi i ngā whakarewa pēnei i te toluene, te xylene, te ethyl acetate, te butyl acetate, te acetone, te butanone rānei i roto i ngā ahumahi peita me te piri. He hua matū matomato e pai ana ki te taiao.
2. He kaihoko pai mō te methylation, te kaihoko carbonylating, te kaihoko hydroxymethylating me te kaihoko methoxylating. He whānuitia te whakamahinga i roto i ngā mara o ngā antioxidants kai, ngā kaihoko tiaki tipu, me ētahi atu. He rauemi matū mata e whakamahia whānuitia ana.
3. He whakakapinga pai mō ngā rongoā tino paitini pērā i te phosgene, te dimethyl sulfate, me te methyl chloroformate.
4. Hangaia te polycarbonate, te diphenyl carbonate, te isocyanate, me ētahi atu.
5. I roto i te rongoā, e whakamahia ana hei hanga i ngā rongoā ārai-mate, ngā rongoā whakaheke-wera me te whakamamae i te mamae, ngā rongoā huaora, me ngā rongoā mō te pūnaha io matua.
6. I roto i ngā patupatu, ka whakamahia nuitia hei hanga i te methyl isocyanate, kātahi ka hanga i ētahi rongoā carbamate me ngā patupatu (anisole).
7. Ngā tāpiringa penehīni, ngā electrolytes pākahiko lithium, me ētahi atu.
