Description

General description

Anhydrous ethylene carbonate is a cyclic ester and chemically related to ethylene glycol and dimethyl carbonate. It is a highly polar solvent and is a good solvent for many organic and inorganic compounds; however, at room temperature (25 °C) ethylene carbonate is a transparent crystalline solid, practically odorless and colorless, and somewhat soluble in water. In the liquid state (m.p. 35-37 °C) ethylene carbonate is a colorless, odorless liquid with a high boiling point (243 °C). Anhydrous ethylene carbonate is a solvent that is commonly used in the production of batteries, particularly lithium-ion batteries, and as a solvent in the pharmaceutical and chemical industries, in part because of its very high dielectric constant. Because of its high melting point and moderate viscosity, ethylene carbonate is often blended with other carbonates to yield a solution at room temperature with lower viscosity.

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.

Caution

These additives have low water content (less than 100 ppm). Please handle under inert and moisture free environment (glove box). Keep containers tightly closed. Keep away from heat and ignition sources. Store in a cool and dry place. Avoid storing together with oxidizers.
