Dimethyl carbonate CAS 616-38-6
Dimethyl carbonate, wanda aka fi sani da DMC, ruwa ne mara launi, mai haske, mai ƙamshi mai kamshi a zafin ɗaki. Yawansa (d204) shine 1.0694, wurin narkewarsa shine 4°C, wurin tafasarsa shine 90.3°C, wurin walƙiyarsa shine 21.7°C (buɗe) da 16.7°C (rufe), ma'aunin amsawarsa (nd20) shine 1.3687, kuma yana da wuta kuma ba ya da guba. Ana iya haɗa shi da kusan dukkanin sinadarai masu narkewa na halitta kamar alcohols, ketones, da esters a kowane rabo kuma yana narkewa kaɗan a cikin ruwa. Ana iya amfani da shi azaman wakilin methylating. Idan aka kwatanta da sauran wakilan methylating, kamar methyl iodide da dimethyl sulfate, dimethyl carbonate ba shi da guba sosai 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. Saboda haka, ana iya amfani da shi sosai a cikin halayen haɗakar kwayoyin halitta kamar carbonylation, methylation, methoxylation da carbonylmethylation. Yana da amfani mai yawa. Ana amfani da shi galibi azaman reagent na carbonylation da methylation, ƙari na fetur, da kuma kayan da aka samar don haɗa polycarbonate (PC). Babban samar da DMC ya haɓaka tare da tsarin haɗakar polycarbonate wanda ba phosgene ba. Amfaninsa sune kamar haka:
1. Wani sabon nau'in sinadarin narkewa mai ƙarancin guba zai iya maye gurbin sinadarai masu narkewa kamar toluene, xylene, ethyl acetate, butyl acetate, acetone ko butanone a masana'antar fenti da manne. Samfurin sinadarai ne masu kare muhalli.
2. Kyakkyawan wakili mai hana methylation, wakilin carbonylating, wakilin hydroxymethylating da wakilin methoxylating. Ana amfani da shi sosai a fannin antioxidants na abinci, magungunan kare tsirrai, da sauransu. Kayan sinadarai ne da ake amfani da su sosai.
3. Madadin magunguna masu guba kamar su phosgene, dimethyl sulfate, da methyl chloroformate.
4. Haɗa polycarbonate, diphenyl carbonate, isocyanate, da sauransu.
5. A fannin magani, ana amfani da shi wajen haɗa magungunan hana kamuwa da cuta, magungunan rage kumburi da rage raɗaɗi, magungunan bitamin, da magunguna ga tsarin jijiyoyi na tsakiya.
6. A cikin magungunan kashe kwari, ana amfani da shi galibi don samar da methyl isocyanate, sannan don samar da wasu magungunan carbamate da magungunan kashe kwari (anisole).
7. Ƙarin mai, batirin lithium electrolytes, da sauransu.
