ʻO ka Dimethyl carbonate, i kapa ʻia ʻo DMC, he wai waihoʻoluʻu ʻaʻole i ʻike ʻia me ka ʻala ʻala ma ka lumi wela. ʻO kona mānoanoa pili (d204) he 1.0694, ʻo kona helu hoʻoheheʻe ʻana he 4°C, ʻo kona wahi paila he 90.3°C, ʻo kona kiko uila he 21.7°C (wehe) a me 16.7°C (pani ʻia), ʻo kona helu hoʻoheheʻe (nd20) ʻo 1.3687, a ʻaʻole hiki ke puhi ʻia a ʻona. Hiki ke hoʻohui ʻia me nā mea hoʻoheheʻe kūlohelohe a pau e like me nā ʻawaʻawa, nā ketones, a me nā esters i kēlā me kēia ʻāpana a hiki ke hoʻoheheʻe iki ʻia i ka wai. Hiki ke hoʻohana ʻia ma ke ʻano he methylating agent. Ke hoʻohālikelike ʻia me nā mea methylating ʻē aʻe, e like me ka methyl iodide a me ka dimethyl sulfate, ʻoi aku ka liʻiliʻi o ka dimethyl carbonate a hiki ke biodegraded.

Loaʻa i ka Dimethyl carbonate (DMC) kahi ʻano molekala kūikawā (CH3O-CO-OCH3). Loaʻa i kāna ʻano molekala nā hui carbonyl, methyl, methoxy a me carbonylmethoxy. No laila, hiki ke hoʻohana nui ʻia i nā hopena synthesis organik e like me carbonylation, methylation, methoxylation a me carbonylmethylation. Loaʻa i ka laulā nui o ka hoʻohana. Hoʻohana nui ʻia e like me ka carbonylation a me ka methylation reagent, kahi mea hoʻohui ʻaila, a me kahi mea maka no ka synthesizing polycarbonate (PC). Ua hoʻomohala ka hana nui o DMC me ke kaʻina hana synthesis non-phosgene o polycarbonate. Penei kona hoohana ana.
1. Hiki i kahi ʻano hou o ka mea hoʻoheheʻe haʻahaʻa haʻahaʻa ke hoʻololi i nā solvents e like me toluene, xylene, ethyl acetate, butyl acetate, acetone a butanone paha i ka pena a me nā ʻoihana hoʻopili. He huahana kemika ʻōmaʻomaʻo e pili ana i ke kaiapuni.
2. He mea methylating maikaʻi, carbonylating agent, hydroxymethylating agent a me methoxylating agent. Hoʻohana nui ʻia ia ma nā kula o nā antioxidants meaʻai, nā mea mālama mea kanu, a me nā mea ʻē aʻe.
3. He pani kūpono no nā lāʻau make loa e like me ka phosgene, dimethyl sulfate, a me ka methyl chloroformate.
4. Synthesize polycarbonate, diphenyl carbonate, isocyanate, etc.
5. I loko o ka lāʻau lapaʻau, hoʻohana ʻia ia e synthesize i nā lāʻau anti-infective, antipyretic a me analgesic lāʻau, nā lāʻau huaʻai, a me nā lāʻau lapaʻau no ka ʻōnaehana nerve waena.
6. I loko o nā pesticides, hoʻohana nui ʻia e hana i ka methyl isocyanate, a laila e hana i kekahi mau lāʻau carbamate a me nā insecticides (anisole).
7. ʻO nā mea hoʻohui ʻaila, lithium battery electrolytes, etc.
