Substitute phosgene as carbonylation agent
Phosgene is highly reactive, but its highly toxic and highly corrosive by-products make it face huge environmental pressure, so it will be gradually eliminated; DMC has a similar nucleophilic reaction center. When the carbonyl group of DMC is attacked by nucleophilic group, the acyl oxygen bond breaks to form carbonyl compounds, and the by-product is methano'l. Therefore, DMC can replace phosgene as a safe reaction agent to synthesize carbonic acid derivatives, such as carbamate pesticides, polycarbonate, isocyanate, etc., of which polycarbonate will be the field with the largest demand for DMC, It is predicted that more than 80% of DMC will be used to produce polycarbonate in 2005.
Substitute dimethyl sulfate as methylation agent
For reasons similar to phosgene, dimethyl sulfate is also faced with the pressure of being eliminated. When the methyl carbon of DMC is attacked by nucleophilic, its alkyl oxygen bond breaks and methylated products are also generated. DMC has higher reaction yield and simpler process than dimethyl sulfate. Its main uses include synthetic organic intermediates, pharmaceutical products, pesticide products, etc.
Low toxic solvent
DMC has excellent solubility, narrow melting and boiling point range, large surface tension, low viscosity, small dielectric constant of medium, high evaporation temperature and fast evaporation rate, so it can be used as a low toxic solvent in the coating industry and pharmaceutical industry. It can be seen that DMC is not only less toxic, but also has the characteristics of high flash point, low vapor pressure and high lower explosive limit in the air. Therefore, DMC is a green solvent with both cleanliness and safety.
