Tsananguro:
Dimethyl carbonate inoonekwa semvura yakajeka, isina ruvara ine hwema hunofadza. Yakaoma kupfuura mvura uye inonyungudika zvishoma mumvura. Utsi hunorema kupfuura mhepo. Hunoshandiswa kugadzira mamwe makemikari uye semushonga unonyungudutsa une chinangwa chakakosha.

Kushandiswa
Dimethyl carbonate inoshandiswa se solvent mu organic synthesis uye inoonekwa senzira yekutsiva solvent yakaita se methyl ethyl ketone, tert-butyl acetate uye parachlorobenzotrifluoride. Inobatanidzwa senzira yepakati mukugadzira diphenylcarbonate, iyo inoshandiswawo sezvinhu zvakakosha pakugadzira Bisphenol-A-polycarbonate. Inoshandiswawo se 'green' methylating agent inobatanidzwa mu methylation yeaniline, phenols uye carboxylic acids. Inogona kushandiswa semafuta ekuwedzera nekuda kwehuwandu hwayo hwe oxygen. Inowanawo mashandisirwo ane chekuita nema supercapacitors ne lithium batterys.
Inotsiva dimethyl sulfate, qv, uye methyl halides zvisina njodzi mukuita kwemethylation uye phosgene, qv, mukuita kwemethylcarbonylation.
Kurongedza uye Kutumira
200KG/Drum kana zvichienderana nezvinodiwa nevatengi.
Ndezvezvinhu zvakajairika uye zvinogona kutumirwa negungwa nemhepo
Chengeta uye chengeta
Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
