1. Instead of phosgene as carbonylation agent

Although the reactive activity of Phosgene (Cl-Co -Cl) is relatively high, its highly toxic and highly corrosive by-products make it face great environmental pressure, so it will be gradually eliminated. And DMC (CH3O - CO - OCH3) have similar nucleophilic reaction center, when the carbonyl DMC nucleophilic attack, acyl - oxygen key fracture, the formation of carbonyl compounds, by-products of methanol, and the DMC can replace phosgene as a safety reaction reagent synthesis of carbonic acid derivatives, such as hydrogen carbamate pesticide, polycarbonate, different acid ester, etc., one of the biggest polycarbonate is DMC demand field, according to a forecast in 2005 more than 80% of the DMC will be used in the production of polycarbonate;

2. Instead of dimethyl sulfate as a methylator

Due to similar reasons to phosgene, dimethyl sulfate (CH3O-sooch3) is also under the pressure of being eliminated, while when the methyl carbon of DMC is attacked by nucleophilic attack, its alkyl-oxygen bond breaks, and methylated products are also generated, and DMC is used for higher reaction yield and simpler process than dimethyl sulfate. Its main uses include synthetic organic intermediates, pharmaceutical products, pesticide products, etc.

3.Low toxic solvent

DMC has excellent solubility, its melting and boiling point range is narrow, the surface tension is large, the viscosity is low, the dielectric boundary electric constant is small, at the same time has the high evaporation temperature and the fast evaporation rate, so it can be used as the low toxic solvent in the coating industry and the pharmaceutical industry. As can be seen from Table 1, DMC is not only less toxic, but also characterized by high flash point, low steam pressure and high lower limit of explosion in air. Therefore, DMC is a green solvent integrating cleanness and safety.
