Incazelo:
I-Dimethyl carbonate ibonakala njengoketshezi olucacile, olungenambala olunephunga elimnandi. Inzima kunamanzi futhi incibilika kancane emanzini. Umhwamuko usinda kunomoya. Usetshenziselwa ukwenza amanye amakhemikhali futhi njengesinyibilikisi senhloso ekhethekile.

Ukusetshenziswa
I-Dimethyl carbonate isetshenziswa njengesinyibilikisi ekuhlanganisweni kwezinto eziphilayo futhi ibhekwa njengokufaka esikhundleni sesinyibilikisi njenge-methyl ethyl ketone, i-tert-butyl acetate kanye ne-parachlorobenzotrifluoride. Ibandakanyeka njengophakathi ekulungiseleleni i-diphenylcarbonate, esetshenziswa njengezinto eziwusizo ezibalulekile ekuhlanganisweni kwe-Bisphenol-A-polycarbonate. Isetshenziswa futhi njenge-ejenti 'eluhlaza' ye-methylating ehilelekile ku-methylation ye-aniline, ama-phenol kanye nama-carboxylic acid. Ingasetshenziswa njengesithasiselo sikaphethiloli ngenxa yokuqukethwe kwayo okuphezulu kwe-oxygen. Iphinde ithole ukusetshenziswa okuhlobene nama-supercapacitors namabhethri e-lithium.
I-dimethyl sulfate, qv, kanye ne-methyl halides engathathi hlangothi ekusabeleni kwe-methylation kanye ne-phosgene, qv, ekusabeleni kwe-methylcarbonylation.
Ukupakisha Nokuthumela
200KG/Isigubhu noma ngokwezidingo zamakhasimende.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
