Dimethyl carbonate, e taʻua o le DMC, o se vai e leai ni lanu, manino ma se manogi manogi i le vevela o le potu. O lona maualuga (d204) o le 1.0694, o lona liusuavai o le 4 ° C, o lona vevela o le 90.3 ° C, o lona moli uila o le 21.7 ° C (tatala) ma le 16.7 ° C (tapuni), o lona faasinomaga faʻataʻitaʻi (nd20) o le 1.3687, ma e le o se mea oona e mu. E mafai ona fa'afefiloi ma toetoe o so'o so'o uma e pei o ava malosi, ketones, ma esters i so'o se vaega ma e solu teisi i le vai. E mafai ona faʻaaogaina e avea o se methylating agent. Pe a faatusatusa i isi methylating agents, e pei o le methyl iodide ma le dimethyl sulfate, o le dimethyl carbonate e itiiti le oona ma e mafai ona faʻaleagaina.

Dimethyl carbonate (DMC) o loʻo i ai se fausaga mole mole tulaga ese (CH3O-CO-OCH3). O lona fausaga mole e aofia ai carbonyl, methyl, methoxy ma carbonylmethoxy vaega. O le mea lea, e mafai ona faʻaaogaina lautele i faʻasologa faʻasolosolo faʻasolosolo e pei o le carbonylation, methylation, methoxylation ma carbonylmethylation. O lo'o i ai le lautele tele o fa'aoga. E masani ona faʻaaogaina e avea o se carbonylation ma methylation reagent, o se faʻapipiʻi penisini, ma se mea mataʻutia mo le faʻapipiʻiina o le polycarbonate (PC). O le gaosiga tele o le DMC ua atiaʻe faʻatasi ma le non-phosgene synthesis process of polycarbonate. O lona fa'aogaina e fa'apea:
1. O se ituaiga fou ole solvent maualalo e mafai ona suitulaga e pei ole toluene, xylene, ethyl acetate, butyl acetate, acetone poʻo butanone ile vali ma faʻapipiʻi alamanuia. Ose vaila'au lanu meamata e fa'alelei le si'osi'omaga.
2. O se sui methylating lelei, carbonylating agent, hydroxymethylating agent ma le methoxylating agent. E masani ona faʻaaogaina i le fanua o meaʻai antioxidants, mea e puipuia ai laau, ma isi mea.
3. O se mea lelei e suitulaga i fualaau oona e pei ole phosgene, dimethyl sulfate, ma le methyl chloroformate.
4. Fa'afefiloi polycarbonate, diphenyl carbonate, isocyanate, ma isi.
5. I vailaʻau, e faʻaaogaina e faʻapipiʻi ai vailaʻau faʻamaʻi, antipyretic ma analgesic vailaʻau, vailaʻau vailaʻau, ma vailaʻau mo le fatugalemu o le tino.
6. I vailaau fa'ato'aga, e masani lava ona fa'aaogaina e gaosia ai le methyl isocyanate, ona maua ai lea o nisi vaila'au fa'ama'i ma iniseti (anisole).
7. Fa'aopoopo penisini, lithium maa electrolytes, ma isi.
