Dimethyl carbonate (DMC) has a unique molecular structure (CH3O-CO-OCH3), and its molecular structure contains carbonyl, methyl, methoxy and carbonyl methoxy, so it can be widely used in organic synthesis reactions such as carbonylation, methylation, methoxylation and carbonyl methylation, and has a very wide range of applications, mainly as carbonylation and methylation reagents, gasoline additives, raw materials for the synthesis of polycarbonate (PC). The mass production of DMC is developed along with the non-phosgene synthesis process of polycarbonate. Its uses are as follows: 

  1. A new type of low-toxic solvent in the paint and adhesive industry can replace toluene, xylene, ethyl acetate, butyl acetate, acetone or butanone and other solvents, is an environmentally friendly green chemical products.

  2. Good methylation agent, carbonylation agent, hydroxymethylation agent and methoxylation agent, widely used in food antioxidants, plant protection agents and other fields.

  3. Is an ideal substitute for phosgene, dimethyl sulfate, methyl chloroformate and other highly toxic products.

  4. Synthesized polycarbonate, diphenyl carbonate, isocyanate, etc.

  5. Used in medicine for the synthesis of anti-infective drugs, antipyretic and analgesic drugs, vitamins, central nervous system drugs.

  6. Used in pesticides, mainly for the production of methyl isocyanate, and then some carbamate drugs, insecticides (anisole).

  7. Gasoline additives, electrolyte for lithium batteries, etc.
