Dimethyl Carbonate
Property and application
Formula: C3H6O3
Structural formula:
Under normal temperature, it is a colorless, transparent liquid with a molecular weight of 90.08. It has a melting point of 4oC and a boiling point of 90.3oCIts index of refraction (ND20), viscosity and latent heat of vaporization are respectively 1.3697, 0.664MPa. S and 8382KJ/Kmol. It can be mixed with such organic solvents as alcohol, ketone, ester, etc. At any proportion but it is slightly soluble in water.
It is a perfect methylating agent, carbonylating agent, methoxylating agent and methylolating agent with active chemical properties. It can be used into produce polypropylene carbonate. In pharmaceutical and pesticide, DMC can be used into produce ciprofloxacin and carbadox. Also it is a indispensable raw material to produce lithium battery electrolyte. Because of its excellent chemical and environmental property, recently DMC is acting as a good solvent for coating, paints, ink and adhesive substituting the benzene, xylene, ethyl acetate, butyl acetate, acetone, butanone, toluene. It is an ideal substitute for toxic substances such as dimethyl sulphate, and methyl chloraformate. Thus, it is a green chemical product.
Appearance
Colorless and transparent liquid, no mechanical impurity
Packing, Storage and Transportation:
The packing is in new galvanized iron drums with the net weight of 200 kg/drum or ISO tank.
It must be stored in a cool and well-ventilated place and dealt with in the same way as inflammable chemical products.
