1. Product Introduction: Ethylene Carbonate CAS 96-49-1 Core Specifications

Ethylene Carbonate (abbreviated as EC, CAS 96-49-1), also known as 1,3-Dioxolan-2-one, is a high-polarity cyclic carbonate organic compound with the molecular formula C₃H₂O₃ and molecular weight of 88.06 g/mol. At room temperature, it appears as colorless transparent crystalline solid, with a melting point of 34–38°C and boiling point of 243–248°C. It features high dielectric constant, excellent chemical stability and strong dissolving capacity, making it one of the most essential base solvents for lithium battery electrolytes and fine chemical industries.

Our factory-standardbattery-grade Ethylene Carbonate adopts advanced closed-loop purification technology to achieve 99.9% purity (GC test standard). We strictly control core quality indicators including ultra-low water content (≤10ppm), low acid value and ultra-trace metal ion residues, effectively avoiding electrochemical failures and material deterioration caused by excessive impurities. Compared with ordinary industrial-grade products, our battery-grade EC has more stable batch consistency and better electrochemical adaptability, which is the core guarantee for high-performance lithium battery electrolyte production.

2. Key Physical & Chemical Properties: Solubility, Water Content & Purity Advantages

The superior industrial applicability of high-quality Ethylene Carbonate is derived from its unique physical and chemical properties. We strictly control every core indicator in Ethylene Carbonate production to ensure product stability and applicability in complex industrial scenarios:

• Excellent Ethylene Carbonate Solubility: Ethylene Carbonate has ultra-high polarity and outstanding mutual solubility with common lithium battery solvents such as DMC, EMC and DEC. It can be uniformly blended with various organic solvents in any proportion to form a homogeneous and stable electrolyte system, effectively improving the ionic conductivity of electrolytes and optimizing battery charging and discharging efficiency. Meanwhile, it also serves as an excellent solvent for polymers such as polyacrylonitrile and polyvinyl chloride, widely used in fine chemical dissolving processing.
• Strictly Controlled Water Content: Moisture is the key factor affecting electrolyte stability and battery safety. Our battery-grade Ethylene Carbonate maintains ultra-low water content below 10ppm through secondary distillation and nitrogen-sealed purification processes. It effectively inhibits hydrolysis reactions and acidic substance generation in electrolytes, prevents battery bulging and capacity attenuation, and greatly improves the long-term stability of lithium-ion batteries.
• Stable 99.9% High Purity: Adhering to high-standard Ethylene Carbonate production processes, our products achieve 99.9% high purity with extremely low organic impurities and metal residues. The high-purity feature ensures no side reactions in electrochemical environments, guarantees the uniformity of SEI film formation on battery electrodes, and significantly enhances battery cycle life and safety performance.

3. Main Ethylene Carbonate Uses in Industrial & Battery Fields

With high dielectric constant, stable chemical properties and strong solubility, battery-grade Ethylene Carbonate has become an indispensable basic material in new energy and fine chemical industries, with extensive and professional Ethylene Carbonate uses:

3.1 Core Solvent for Lithium-Ion Battery Electrolytes

This is the most mainstream application of battery-grade Ethylene Carbonate. As a high-polarity base solvent, it is mixed with linear carbonate solvents to prepare lithium battery electrolytes. It can promote uniform and dense SEI film formation on the anode surface, reduce battery internal resistance, improve electrolyte ionic conductivity, and significantly enhance the cycle stability, low-temperature performance and safety of power batteries, consumer batteries and energy storage batteries.

3.2 Fine Chemical Synthesis Intermediate

Ethylene Carbonate (CAS 96-49-1) is an important organic synthesis intermediate, widely used in the transesterification reaction to produce dimethyl carbonate (DMC), glycerol carbonate and other high-value fine chemicals. It can also participate in ring-opening polymerization reactions to synthesize polyurethane materials, providing core raw material support for the polymer material industry.

3.3 Industrial High-Efficiency Solvent & Auxiliary

Thanks to its excellent solubility, EC is widely used as a solvent for polymer materials, textile finishing agents, plastic foaming agent stabilizers and lubricant additives. It can effectively improve the processing performance of materials and is widely applied in textile, plastic processing and mechanical lubrication industries.

3.4 Electronic Component Manufacturing

High-purity Ethylene Carbonate is also used in the production of supercapacitors and electronic capacitors, serving as an electrolyte solvent to ensure stable electrical performance and long service life of electronic components.
