Introduction
Dimethyl carbonate (DMC) is an organic compound. It is a colorless, transparent, slightly odorous, slightly sweet liquid at room temperature. It has a melting point of 4°C, a boiling point of 90.1°C, and a density of 1.069g/cm³. It is insoluble in water, but can be miscible with almost all organic solvents such as alcohols, ethers, and ketones.
Dimethyl carbonate has many excellent properties and a wide range of uses:
Dimethyl carbonate has a similar nucleophilic reaction center and can replace phosgene as a safe reaction reagent for the synthesis of carbonic acid derivatives.
Replace dimethyl sulfate as a methylating agent: Using dimethyl carbonate for methylation reaction has a higher yield and a simpler process. It can be used to synthesize organic intermediates, pharmaceutical products, pesticide products, etc.
As a low-toxic solvent: it has excellent solubility properties, a narrow melting and boiling point range, high surface tension, low viscosity, small dielectric constant, high evaporation temperature and fast evaporation rate, low toxicity, and also has the characteristics of high flash point, low vapor pressure and high lower explosion limit in air. It is a green solvent that combines cleanliness and safety and can be used in the coating industry and pharmaceutical industry, etc.
