Dimethyl carbonate CAS 616-38-6
Dimethyl carbonate, wanda ake magana da shi a matsayin DMC, ruwa ne mara launi, bayyananne tare da ƙamshi mai ƙamshi a cikin ɗaki. Matsakaicin girmansa (d204) shine 1.0694, wurin narkewar sa shine 4°C, wurin tafasarsa shine 90.3°C, madaidaicin walƙiyarsa shine 21.7°C (buɗe) da 16.7°C (rufe), index ɗinsa na refractive (nd20) shine 1.3687, kuma baya iya ƙonewa kuma baya iya ƙonewa. Ana iya haɗe shi da kusan dukkanin kaushi na halitta kamar su alcohols, ketones, da esters a kowane rabo kuma yana ɗan narkewa cikin ruwa. Ana iya amfani dashi azaman wakili na methylating. Idan aka kwatanta da sauran nau'ikan methylating, irin su methyl iodide da dimethyl sulfate, dimethyl carbonate ba shi da guba kuma ana iya lalata shi.

Dimethyl carbonate (DMC) yana da tsarin kwayoyin halitta na musamman (CH3O-CO-OCH3). Tsarin kwayoyin halittarsa ya ƙunshi ƙungiyoyin carbonyl, methyl, methoxy da carbonylmethoxy. Sabili da haka, ana iya amfani dashi ko'ina a cikin halayen halayen ƙwayoyin halitta kamar carbonylation, methylation, methoxylation da carbonylmethylation. Yana da fa'idar amfani da yawa. An yafi amfani dashi azaman carbonylation da methylation reagent, ƙarar mai, da ɗanyen abu don haɗa polycarbonate (PC). Babban yawan samar da DMC ya ci gaba tare da tsarin da ba na phosgene ba na polycarbonate. Amfaninsa sune kamar haka:
1. Wani sabon nau'i na ƙananan ƙwayar cuta mai guba zai iya maye gurbin abubuwan da ake amfani da su kamar toluene, xylene, ethyl acetate, butyl acetate, acetone ko butanone a cikin masana'antun fenti da mannewa. Samfurin sinadarai ne mai ma'amala da muhalli.
2. Kyakkyawan methylating wakili, carbonylating wakili, hydroxymethylating wakili da methoxylating wakili. An yi amfani da shi sosai a cikin fagage na abinci na antioxidants, magungunan kare tsire-tsire, da dai sauransu. Yana da albarkatun da ake amfani da shi sosai.
3. Kyakkyawan madadin magungunan ƙwayoyi masu guba kamar su phosgene, dimethyl sulfate, da methyl chloroformate.
4. Synthesize polycarbonate, diphenyl carbonate, isocyanate, da dai sauransu.
5. A cikin magani, ana amfani da shi don haɗa magungunan anti-infective, antipyretic da analgesic kwayoyi, bitamin kwayoyi, da kwayoyi don tsarin juyayi na tsakiya.
6. A cikin magungunan kashe qwari, an fi amfani da shi don samar da methyl isocyanate, sannan a samar da wasu magungunan carbamate da magungunan kwari (anisole).
7. Gasoline additives, lithium baturi electrolytes, da dai sauransu.
