Ethylene Carbonate (CAS 96-49-1) – High-Purity Solvent for Batteries & Industry

Introduction:

Ethylene Carbonate is a colorless, odorless, and highly polar organic compound used mainly as a solvent and electrolyte component in lithium-ion batteries. It is also used in chemical synthesis, industrial lubricants, and gas treatment processes. becuase of its high dielectric constant, good thermal stability, and ability to dissolve lithium salts, ethylene carbonate is an essential chemical in the battery and electronics industries. Its low toxicity and biodegradability is more safer and environmentally friendly option compared to many traditional solvents.

Ethylene carbonate is a cyclic carbonate ester with strong solvency properties and excellent electrochemical performance. It is commonly used in combination with other carbonates like dimethyl carbonate (DMC), diethyl carbonate (DEC), or ethyl methyl carbonate (EMC) to create effective electrolyte solutions for high-performance batteries.

How Ethylene Carbonate is made:

When carbon dioxide and ethylene oxide react with a catalyst present, ethylene carbonate is created.  This reaction forms a five-membered ring carbonate compound. The process is efficient and does not generate toxic byproducts, making it more sustainable than older synthesis methods that used phosgene.
The process typically uses the following raw materials:

• Ethylene oxide
• Carbon dioxide (CO₂)
• Catalysts (e.g., quaternary ammonium salts or metal-based catalysts)
• The reaction occurs under moderate pressure and temperature and is followed by purification and distillation steps to remove unreacted materials and ensure high product purity. The final product is usually a clear solid at room temperature but melts to a viscous liquid slightly above 36°C.

Industrial usage:

• Lithium-ion battery electrolytes are the main use for ethylene carbonate. It helps batteries work better with electrolytes, last longer and store more energy. By using ethylene carbonate, a reliable solid electrolyte interphase (SEI) is created on the battery anode which contributes to both safety and good performance. It is used in electric vehicle batteries, consumer electronics, power storage units, and industrial energy systems.
• In the chemical industry, ethylene carbonate is used as a high-permittivity solvent and a chemical intermediate. It is used in the synthesis of dimethyl carbonate (DMC) and other carbonates, which are also important battery solvents and environmentally friendly alternatives to halogenated solvents.
• Ethylene carbonate is used in gas treatment, especially for carbon dioxide and hydrogen sulfide removal in natural gas and petrochemical plants. It serves as a key component in physical solvent systems due to its high solubility for acidic gases.
• In lubricants and greases, ethylene carbonate is added to formulations to improve flow, reduce friction, and enhance temperature resistance. It is particularly useful in synthetic lubricants for automotive and industrial machinery.
• In coatings and adhesives, it may be added to help with flexibility and lasting power. It may play the role of a reactive diluent or stabilizer as well.

Country of origin:

• Many countries with advanced chemical industries produce ethylene carbonate.
• Ethylene carbonate is mostly produced and exported from China. Manufacturers in China offer both battery-grade and industrial-grade materials for global distribution at competitive prices.
• India has a growing presence in the ethylene carbonate market, producing and exporting to neighboring Asian and Middle Eastern countries.
• Germany and other European countries produce high-purity, REACH-compliant ethylene carbonate used in batteries, electronics, and chemical synthesis. These producers focus on quality, traceability, and regulatory compliance.
• South Korea and Japan specialize in ultra-high purity ethylene carbonate used in premium lithium-ion batteries for electric vehicles and consumer electronics.
• The United States produces ethylene carbonate primarily for domestic consumption in the electronics, battery, and petrochemical industries.
