      Product name: Dimethyl carbonate 

      Type: Dimethyl carbonate
      Product introduction:
       Abbr.DMC, Is a low toxicity, Uses an extremely wide range of organic synthesis intermediates, the "green-based Chemical raw materials," said its Structural formula of CH3COOCH3, DMC Chemical lively nature, molecules containing methyl, carbonyl and ester groups three functions group, and with a variety of alcohols, phenols, amines, esters and alcohols, etc. Ammonia series of reactions. DMC low toxicity, can replace highly toxic phosgene (COCl2) satisfaction, dimethyl sulfate ((CH3)2SO4), methylene chloride (CH3Cl) or chlorine Formic acid methyl ester (ClCOOCH3) as the methylating agent, carbonylation agent methyl agent, can easily produce anisole, phenol ether, Ammonia-based Formic acid ester, isocyanate , carbonate and other organic chemical raw materials, synthetic resins advanced medicine (such as ciprofloxacin, furazolidone) and pesticide intermediates, food additives, antioxidants, surfactants fine chemical products, it is a good performance efficient solvent, can replace toxic aromatic solvents in many places, but also as a gasoline additive to improve gasoline octane and oxygen to produce unleaded gasoline, the DMC also known as organic synthetic "new foundation."
