CAS No:         623-53-0 
M.F.:               C4H8O3
S.F.             
Hazard class     
3
UN NO.         
2366
Property:       It has a melting point of –14.5℃ and a boiling point of 109.2℃.  It can be mixed with such organic solvents as alcohol, ketone, ester, etc. at any proportion but it is slightly soluble in water.
Application:     It is newly springing us chemical, which is an excellent solvent for lithium cell electrolyte. Thanks to its methyl and ethyl groups, Ethyl Methyl Carbonate possesses characteristics of both dimethyl carbonate and ethyl carnonate. EMC/MEC is also a solvent of special flavors and intermediates.
Packing:        200KG Iron drum, 16MT/20’FCL.

Property:     It has a melting point of 4℃ and a boiling point of 90.3℃. It can be mixed with such organic solvents as alcohol ,ketone ,ester, etc. at any proportion but it is slightly soluble in water.
Application:   It is a perfect methylating agent,carbonylating agent, meth xylating agent and methyloaring 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 sovent 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 phosgene, dimethyl sulphate, and methyl chloraformate. Thus, it is a green chemical product.

UN NO.       1161
Property:      It has a melting point of -43℃ and a boiling point of 126.8℃. It can be mixed with such organic solvents as alcohol,ketone,ester,etc. at any proportion but it is slightly soluble in water.
Application:  It is fine solvent and textile auxiliary agent and widely used as ehylating, carbonating and carbonaylethoxylating reagents in organic synthesis and as solvents of nitro-cotton, cellulose ether, synthetic resin and natural resin. In the textile printing and dying industry, diethyl carbonate could make dyeing uniformity and increase fading assistance against sunshine, as solvent of resin, it is a nice solvent of polyamide, polyacrylonitrile and diphenol resin and can improve feel of the textiles and anti-crease quality in the synthetic fiber industry, used as paint remover, used to prepare the electrolyte in the synthetic and lithium cells. And in the pharmaceutical industry, diethyl carbonate is the basic ingredient of nard and used to synthesize intermediate Phenobarbital ext., thus has extensive market-developing prospect.
