Ukusetyenziswa
I-Dimethyl carbonate isetyenziswa njengesinyibilikisi kwi-organic synthesis kwaye ithathwa njengendawo yokutshintsha isinyibilikisi esifana ne-methyl ethyl ketone, i-tert-butyl acetate kunye ne-parachlorobenzotrifluoride. Ibandakanyeka njenge-intermediate ekulungiseleleni i-diphenylcarbonate, ethi yona isetyenziswe njengezinto eziphambili zokwenziwa kwe-Bisphenol-A-polycarbonate. Ikwasetyenziswa njenge-arhente ye-methylating 'eluhlaza' ebandakanyeka kwi-methylation ye-aniline, i-phenols kunye ne-carboxylic acids. Ingasetyenziswa njenge-fuel additive ngenxa yomxholo wayo ophezulu we-oxygen. Ikwafumana izicelo ezinxulumene ne-supercapacitors kunye neebhetri ze-lithium.
I-dimethyl sulfate, qv, kunye ne-methyl halides ezithatha indawo ye-methylation kwi-methylation reactions nakwi-phosgene, qv, kwi-methylcarbonylation reactions.
Ukupakishwa kunye nokuthunyelwa
200KG/Idrama okanye ngokweemfuno zomthengi.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
