What Is Ethylene Carbonate (CAS 96-49-1)?
Ethylene Carbonate (CAS 96-49-1), also known as 1,3-dioxolan-2-one, is a cyclic organic carbonate with the molecular formula C₃H₄O₃. At room temperature, it appears as a colorless solid (melting point: 36°C) and transforms into a clear, odorless liquid when heated. What makes it stand out? Its high dielectric constant and excellent thermal stability make it one of the most effective solvents for dissolving lithium salts in the battery industry.
Moreover, because of its low volatility and biodegradability, EC has gained widespread adoption as a green solvent in industrial settings, replacing more hazardous traditional options.
Key Applications: Where to Use Ethylene Carbonate
🔋 Lithium Battery Electrolyte Solvent (Primary Market)
Today, the single largest driver of the Ethylene Carbonate market is the lithium-ion battery industry. As a core component of electrolyte formulations, high-purity EC (99.99%) offers several critical benefits:
-
It efficiently dissolves lithium salts (e.g., LiPF₆).
-
It helps form a stable solid-electrolyte interphase (SEI).
-
It enhances battery cycle life and overall safety.
As the world shifts rapidly toward electric vehicles (EVs) and renewable energy storage, demand for battery-grade Ethylene Carbonate continues to surge. Consequently, battery manufacturers across Asia, Europe, and North America trust our product for its consistency and performance.
🛢️ Industrial Lubricants & Metalworking Fluids
In addition to battery applications, it serves as a polarity modifier and extreme-pressure additive in synthetic lubricants. It proves especially valuable in environmentally sensitive sectors—such as marine and forestry equipment—where biodegradability is not optional but mandatory.
🎨 Coatings, Plastics & Chemical Intermediates
Beyond lubricants, EC finds use in several other industrial areas:
-
Surface Coatings: It functions as a high-boiling solvent for polymers, resins, and dyes.
-
Plasticizer: It improves flexibility in plastics and polymer films.
-
Chemical Intermediate: It serves as a precursor for producing polycarbonates, Dimethyl Carbonate (DMC), and glycols—offering a safer, greener alternative to phosgene-based routes.
💊 Pharmaceuticals & Personal Care
Finally, due to its low toxicity and excellent solvency, EC also appears in pharmaceutical synthesis and personal care products such as lotions and hygiene formulations.
