USE
Dimethyl carbonate is briefly referred to as DMC. At room temperature, it is a colorless and transparent liquid with a pungent odor with a relative density (D204) of 1.0694, a melting point of 4 °C, boiling point of 90.3 °C, the flash point being 21.7 °C (opening) and being 16.7 °C (closed ) and the refractive index (nd20) being 1.3687. It is flammable and non-toxic and is miserable with almost all organic solvents in any proportion with alcohols, ketones and esters. It is slightly soluble in water. It can be used as the methylating agent. Compared with other methylating reagent such as methyl iodide and dimethyl sulfate, dimethyl carbonate is less toxic, and biodegradable. <br/> The past method of making dimethyl carbonate with phosgene as raw materials is not frequently used. Instead, people now adopt the catalytic oxidative carbonylation of methanol in the presence of oxygen which is more environmentally friendly than the previous method.<br/> Dimethyl carbonate can enable to methylation of aniline, phenol and carboxylic acid. However, many reaction demands high-pressure. DBU can be added during reflux of DMC for catalyzing the methylation of carboxylic acid with dimethyl carbonate.<br/> <img src="/NewsImg/2016-07-30/2016730141289278.jpg" alt="" /><br />
