| Application: | Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance. |
| General description: | Anhydrous ethyl methyl carbonate (EMC) is a clear, colorless liquid with a sweet, ether-like odor. It is a highly polar solvent with a moderate boiling point (101 °C) and relatively low vapor pressure, making it suitable for use in a wide range of chemical reactions and processes. EMC is an excellent solvent for many organic compounds including cellulose, ester, and amides, and it can dissolve a variety of inorganic compounds as well, including many electrolytic salts. |
| General description: | We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Ethyl methyl carbonate (EMC) enables cleaner energy storage as a key lithium-ion battery electrolyte solvent. Click here ![]() |
