Dimethyl carbonate (DMC), chemical C3H6O3, molecular weight is 90.08, and is a transparent liquid at room temperature, with a slight fragrance. It is difficult to dissolve in water, but it can be miscible with any ratio of alcohol, ketone, esters, etc. DMC is an important organic synthesis intermediate. DMC molecules contain carbonyl, methyl, methoxy and other groups, which have good reaction performance. They can replace highly toxic phosgene, dimethyl sulfate, chloromethane, etc. as carbonylation agents, methylating agents and methoxylated agents. They have the characteristics of safe use, convenient, less contamination and easy transportation in production. They are called 'new base blocks in the field of organic synthesis in the 21st century'. In addition, DMC is also widely used in pesticides, medicines, fragrances, fuel additives, solvents and electronics industries.
