Dimethyl carbonate, yomwe imatchedwa DMC, ndi madzi opanda mtundu, owoneka bwino komanso onunkhira bwino komanso otentha kutentha. Kachulukidwe kake (d204) ndi 1.0694, malo osungunuka ndi 4 ° C, malo ake otentha ndi 90.3 ° C, kung'anima kwake ndi 21.7 ° C (otseguka) ndi 16.7 ° C (kutsekedwa), refractive index (nd20) ndi 1.3687, ndipo siwopsereza. Ikhoza kusakanikirana ndi pafupifupi zosungunulira zonse za organic monga ma alcohols, ketoni, ndi ester mugawo lililonse ndipo zimasungunuka pang'ono m'madzi. Itha kugwiritsidwa ntchito ngati methylating agent. Poyerekeza ndi mankhwala ena a methylating, monga methyl iodide ndi dimethyl sulfate, dimethyl carbonate ilibe poizoni wochepa ndipo imatha kuwonongedwa.

Dimethyl carbonate (DMC) ili ndi mawonekedwe apadera a maselo (CH3O-CO-OCH3). Mapangidwe ake a maselo ali ndi magulu a carbonyl, methyl, methoxy ndi carbonylmethoxy. Choncho, amatha kugwiritsidwa ntchito kwambiri muzochitika za organic synthesis monga carbonylation, methylation, methoxylation ndi carbonylmethylation. Ili ndi mitundu yambiri yogwiritsira ntchito. Amagwiritsidwa ntchito makamaka ngati carbonylation ndi methylation reagent, chowonjezera mafuta, ndi zopangira synthesizing polycarbonate (PC). Kupanga kwakukulu kwa DMC kwachitika limodzi ndi njira yopanda phosgene ya polycarbonate. Magwiritsidwe ake ndi awa:
1. Mtundu watsopano wa zosungunulira zotsika kwambiri ukhoza m'malo mwa zosungunulira monga toluene, xylene, ethyl acetate, butyl acetate, acetone kapena butanone mu mafakitale a utoto ndi zomatira. Ndi chilengedwe wochezeka wobiriwira mankhwala mankhwala.
2. Mankhwala abwino a methylating, carbonylating agent, hydroxymethylating agent ndi methoxylating agent. Amagwiritsidwa ntchito kwambiri m'minda ya antioxidants chakudya, zoteteza zomera, etc. Ndi chimagwiritsidwa ntchito mankhwala zopangira.
3. M'malo mwa mankhwala oopsa kwambiri monga phosgene, dimethyl sulfate, ndi methyl chloroformate.
4. Pangani polycarbonate, diphenyl carbonate, isocyanate, etc.
5. Mu mankhwala, amagwiritsidwa ntchito popanga mankhwala oletsa tizilombo toyambitsa matenda, antipyretic ndi analgesic mankhwala, mankhwala a vitamini, ndi mankhwala apakati a mitsempha.
6. Mu mankhwala ophera tizilombo, amagwiritsidwa ntchito makamaka popanga methyl isocyanate, kenako kupanga mankhwala ena a carbamate ndi mankhwala ophera tizilombo (anisole).
7. Zowonjezera mafuta, lithiamu batire electrolytes, etc.
