Dimethyl carbonate, hu ua DMC, yog cov kua tsis muaj xim, pob tshab nrog cov ntxhiab tsw ntawm chav tsev kub. Nws tus txheeb ze ntom ntom (d204) yog 1.0694, nws cov ntsiab lus melting yog 4 ° C, nws qhov kub kub yog 90.3 ° C, nws qhov taw tes flash yog 21.7 ° C (qhib) thiab 16.7 ° C (kaw), nws qhov taw qhia tsis pom kev (nd20) yog 1.3687, thiab nws tsis muaj tshuaj lom thiab flammable. Nws tuaj yeem sib xyaw nrog yuav luag txhua cov kuab tshuaj organic xws li cawv, ketones, thiab esters hauv ib qho kev faib ua feem thiab yog me ntsis soluble hauv dej. Nws tuaj yeem siv los ua tus neeg sawv cev methylating. Piv nrog rau lwm cov tshuaj methylating, xws li methyl iodide thiab dimethyl sulfate, dimethyl carbonate tsis muaj tshuaj lom thiab tuaj yeem ua rau biodegraded.

Dimethyl carbonate (DMC) muaj cov qauv molecular tshwj xeeb (CH3O-CO-OCH3). Nws cov qauv molecular muaj carbonyl, methyl, methoxy thiab carbonylmethoxy pawg. Yog li ntawd, nws tuaj yeem siv dav hauv cov organic synthesis tshuaj xws li carbonylation, methylation, methoxylation thiab carbonylmethylation. Nws muaj ntau yam kev siv. Nws yog siv los ua carbonylation thiab methylation reagent, roj av additive, thiab raw khoom rau synthesizing polycarbonate (PC). Kev tsim khoom loj ntawm DMC tau tsim nrog cov txheej txheem tsis-phosgene synthesis ntawm polycarbonate. Nws cov kev siv yog raws li nram no:
1. Ib hom tshiab ntawm cov kuab tshuaj tsis zoo tuaj yeem hloov cov kuab tshuaj xws li toluene, xylene, ethyl acetate, butyl acetate, acetone los yog butanone hauv cov xim thiab cov khoom lag luam nplaum. Nws yog ib puag ncig tus phooj ywg ntsuab tshuaj lom neeg cov khoom.
2. Ib tug zoo methylating agent, carbonylating agent, hydroxymethylating agent thiab methoxylating agent. Nws yog dav siv nyob rau hauv cov teb ntawm cov zaub mov antioxidants, cov nroj tsuag tiv thaiv kab mob, thiab lwm yam. Nws yog ib tug dav siv tshuaj raw khoom.
3. Ib qho kev hloov zoo tshaj plaws rau cov tshuaj lom neeg xws li phosgene, dimethyl sulfate, thiab methyl chloroformate.
4. Synthesize polycarbonate, diphenyl carbonate, isocyanate, thiab lwm yam.
5. Hauv cov tshuaj, nws yog siv los tsim cov tshuaj tiv thaiv kab mob, tshuaj tua kab mob thiab tshuaj tua kab mob, tshuaj vitamin, thiab tshuaj rau lub hauv paus paj hlwb.
6. Hauv cov tshuaj tua kab, nws tsuas yog siv los tsim methyl isocyanate, thiab tom qab ntawd los tsim qee yam tshuaj carbamate thiab tshuaj tua kab (anisole).
7. Gasoline additives, lithium roj teeb electrolytes, thiab lwm yam.
