I-Dimethyl carbonate
1) Kuyi-ejenti ye-methylating ephelele, i-carbonylating agent, i-methoxylating ejenti kanye ne-methylolating enezici zamakhemikhali ezisebenzayo.Ingasetshenziselwa ukukhiqiza i-polypropylene carbonate.
2)Emakhemisi nasesibulala-zinambuzane, i-DMC ingasetshenziswa ukukhiqiza i-ciprofloxacin ne-carbadox.Futhi kuyimpahla eluhlaza engabalulekile ukukhiqiza i-lithium battery electrolyte.Ngenxa yempahla yayo ehle kakhulu yamakhemikhali nemvelo, muva nje i-DMC isisebenza njengesinyibilikisi esihle sokunameka, upende, uyinki nokunamathela esikhundleni se-benzene, xylene, ethyl acetate, butyl acetate, acetone, butanone, toluene.Iyindawo ekahle yezinto ezinobuthi njenge-phosgene, i-dimethyl sulphate, ne-methyl chloraformate.
3) Dimethyl carbonate (DMC), iwuhlobo ezibalulekile intermediates synthesis organic, isakhiwo samangqamuzana iqukethe carbonyl, methyl kanye zempi, ezifana oxygen iqembu ukusebenza, has ezihlukahlukene yokusabela ukusebenza ekuphepheni ukukhiqizwa, elula, abe ukusetshenziswa ukungcola kancane, kulula ukuthutha zonke lezo zici.Ngenxa yobuthi obuphansi i-dimethyl carbonate, iwumkhiqizo wamakhemikhali "oluhlaza" ongaba khona.
