Description

Ethyl Methyl Carbonate (CAS No. 623-53-0) is a high-purity carbonate ester solvent with the molecular formula C₄H₈O₃. This colorless, low-viscosity liquid is widely recognized for its excellent electrochemical stability, high dielectric constant, and low volatility, making it a preferred choice for advanced electrolyte formulations in lithium-ion batteries. With a boiling point of approximately 108-110??C and a flash point around 25??C, it offers optimal performance in high-energy-density applications. Our product is rigorously tested to ensure ??99.9% purity, with stringent controls for water content (<50 ppm) and acid value (<0.01 mg KOH/g). Packaged under nitrogen atmosphere in chemically resistant containers to maintain stability, this reagent-grade solvent meets the exacting standards of battery research, organic synthesis, and specialty chemical manufacturing.

Application

Ethyl Methyl Carbonate serves as a critical co-solvent in lithium-ion battery electrolytes, where it enhances ionic conductivity and improves low-temperature performance. Its balanced solvation properties make it ideal for formulating electrolytes with lithium salts such as LiPF₆ or LiBF₄. The compound also finds use as a polar aprotic solvent in organic synthesis, particularly for Grignard reactions and carbonate transesterifications. In specialty coatings, it functions as a high-performance coalescing agent due to its favorable evaporation rate and solvency power.
