O le a manuia lau pisinisi pe afai e te filifili e galulue fa'atasi ma se kamupani gaosi oloa agavaa. Talia lau galulue fa'atasi!
O le Dimethyl carbonate, e ta'ua o le DMC, o se vai e leai se lanu, manino ma e iai sona manogi malosi i le vevela o le potu. O lona mafiafia fa'atatau (d204) e 1.0694, o lona tulaga fa'a'asu e 4°C, o lona tulaga pupuna e 90.3°C, o lona tulaga fa'amumu e 21.7°C (tatala) ma le 16.7°C (tapuni), o lona fa'asinomaga fa'afo'i (nd20) e 1.3687, ma e mu ma e le o'ona. E mafai ona fa'afefiloi ma toetoe lava o vaila'au fa'aola uma e pei o le 'ava malosi, ketones, ma esters i so'o se fua fa'atatau ma e fai si so'ona fa'a'asu i le vai. E mafai ona fa'aaogaina o se vaila'au methylating. Pe a fa'atusatusa i isi vaila'au methylating, e pei o le methyl iodide ma le dimethyl sulfate, e itiiti le o'ona o le dimethyl carbonate ma e mafai ona pala.

O le Dimethyl carbonate (DMC) e iai lona fausaga fa'a-molecular tulaga ese (CH3O-CO-OCH3). O lona fausaga fa'a-molecular e aofia ai vaega o le carbonyl, methyl, methoxy ma le carbonylmethoxy. O le mea lea, e mafai ona fa'aaogaina lautele i fa'agasologa o le fa'aputuina o meaola e pei o le carbonylation, methylation, methoxylation ma le carbonylmethylation. E tele naua ona fa'aoga. E masani ona fa'aaogaina o se reagent carbonylation ma le methylation, o se fa'aopoopoga penisini, ma se mea mata mo le fa'aputuina o le polycarbonate (PC). O le gaosiga tele o le DMC ua atia'e fa'atasi ai ma le fa'agasologa o le fa'aputuina o le polycarbonate e le o ni phosgene. O ona fa'aoga e fa'apea:
1. O se ituaiga fou o vailaʻau faʻamama e maualalo le oʻona e mafai ona suitulaga i vailaʻau faʻamama e pei o le toluene, xylene, ethyl acetate, butyl acetate, acetone poʻo le butanone i pisinisi vali ma mea faʻapipiʻi. O se oloa vailaʻau lanumeamata e le afaina ai le siosiomaga.
2. O se sui lelei e fa'amamā ai le methylation, sui e fa'acarbonylating, sui e fa'ahydroxymethylating ma sui e fa'ametoxylating. E fa'aaogaina lautele i vaega o mea'ai e tete'e atu i le antioxidants, sui e puipuia ai la'au, ma isi mea fa'apena. O se mea mata e fa'aaogaina lautele.
3. O se sui lelei mo vailaʻau e matua oona e pei o le phosgene, dimethyl sulfate, ma le methyl chloroformate.
4. Fa'aputu le polycarbonate, diphenyl carbonate, isocyanate, ma isi.
5. I vailaʻau faʻafomaʻi, e faʻaaogaina e faʻaputu ai vailaʻau e teteʻe ai i faʻamaʻi pipisi, vailaʻau e faʻaitiitia ai le fiva ma faʻaitiitia ai le tiga, vailaʻau vitamini, ma vailaʻau mo le faiga tutotonu o neula.
6. I vaila'au fa'asaina iniseti, e masani ona fa'aaogaina e gaosia ai le methyl isocyanate, ona gaosia ai lea o nisi vaila'au carbamate ma vaila'au fa'asaina iniseti (anisole).
7. Fa'aopoopoga penisini, electrolytes o le maa lithium, ma isi mea fa'apena.
