Dimethyl Carbonate
1) O se sui methylating atoatoa, carbonylating agent, methoxylating agent ma methylolating agent faʻatasi ai ma vailaʻau faʻamalosi.E mafai ona faʻaaogaina e gaosia ai le polypropylene carbonate.
2) I vailaʻau ma vailaau faʻasaina, DMC e mafai ona faʻaaogaina e gaosia ai le ciprofloxacin ma le carbadox.E le gata i lea, o se mea taua tele e gaosia ai le eletise eletise lithium.Talu ai ona o lona vailaʻau sili ona lelei ma le siosiomaga, talu ai nei o loʻo galue le DMC o se solvent lelei mo le ufiufi, vali, vaitusi ma faʻapipiʻi e suitulaga i le benzene, xylene, ethyl acetate, butyl acetate, acetone, butanone, toluene.O se mea lelei e suitulaga i mea oona e pei ole phosgene, dimethyl sulphate, ma le methyl chloraformate.
3) Dimethyl carbonate (DMC), o se ituaiga o intermediates organic synthesis, mole mole fausaga e aofia ai carbonyl, methyl ma ofutau, e pei o le vaega o le okesene, ei ai le tele o gaioiga tali atu i le saogalemu o le gaosiga, faigofie, faʻaitiitia le faʻaleagaina, faigofie ona felauaiga na uiga uma.Ona o le maualalo o le oona o le dimethyl carbonate, o se mea e mafai ona "lanumeamata" vailaʻau.
