| Overview | Ethyl Methyl Carbonate (Ethyl Carbonate) alias Ethyl Methyl Carbonate, is a colorless transparent liquid, insoluble in water, can be used in organic synthesis, is an excellent lithium ion battery electrolyte solvent, is the latest product with dimethyl carbonate and lithium ion battery output increases, because it has both methyl and ethyl, both dimethyl carbonate, diethyl carbonate excellent characteristics. ethyl methyl carbonate contains active reactive groups such as methyl, ethyl and carbonyl groups, and can be reacted with alcohols, phenols, amines and esters as fine synthesis intermediates. The asymmetry of its molecular structure makes it also show obvious advantages as a solvent such as paint, cellulose and resin. Due to the solubility of lithium salt, safety and stability, methyl ethyl carbonate can not only improve the energy density and discharge capacity of the battery, but also has long cycle life, good safety performance, no memory effect, good low temperature performance and other characteristics, has been widely used in mobile phones, portable audio-visual equipment, notebook computers and other high-end electrical appliances, is the most promising small secondary battery electrolyte solvent, its advantages have been widely recognized by the industry. |
| Application | used in organic synthesis used in organic synthesis used as electrolyte solvent of lithium ion battery, it can also be used as a solvent for special fragrances and intermediates. |
| production method | can be obtained by reacting methyl chloroformate with ethanol. |
