Ethyl methyl carbonate CAS 623-53-0 EMC

Ethylmethyl carbonate, also known as EthylMethylCarbonate, is a colorless and transparent liquid that is insoluble in water. It can be used in organic synthesis and is an excellent solvent for lithium-ion battery electrolytes. It is the latest product that has emerged with the increase in the production of dimethyl carbonate and lithium-ion batteries. Due to its presence of both methyl and ethyl groups, It has the excellent properties of both dimethyl carbonate and diethyl carbonate. Methyl ethyl carbonate contains active reactive groups such as methyl, ethyl and carbonyl groups. As a fine synthetic intermediate, it can react with alcohols, phenols, amines and esters, etc. The asymmetry of its molecular structure also makes it show obvious superiority as a solvent for paints, cellulose and resins, etc. Methyl ethyl carbonate, due to its strong solubility in lithium salts, safety and stability, can not only enhance the energy density and discharge capacity of batteries, but also has the characteristics of long cycle life, good safety performance, no memory effect, and excellent low-temperature performance. It has been widely used in high-end electrical appliances such as mobile phones, portable audio-visual equipment, and notebook computers. It is currently the most promising electrolyte solvent for small secondary batteries, and its advantages have been widely recognized by the industry.
