Properties：It is a colorless transparent liquid. Soluble in alcohol, ether and other organic solvents, Insoluble in water. Relative density (d20/4): 1.0±0.1g/cm3, Melting point: -14.5℃, Boiling point: 109.2℃, Flash point: 26.7℃±7.8℃, Refractive index: 1.379.

Uses：Methyl ethyl carbonate is an aprotic, polar and environment-friendly organic solvent. It has strong solubility to lithium salt, and is safe and stable. It can improve the energy density and discharge capacity of the battery, and has the characteristics of long cycle life, good safety performance, no memory effect, good low temperature performance, etc. It has been widely used in mobile phones, portable audio-visual equipment, laptops and other high-end electrical appliances. It is currently the most promising small secondary battery electrolyte solvent, its advantages have been widely recognized by the industry.

Storage：Store in a cool, dry and well ventilated warehouse. Keep away from fire and heat source. Stop separately with oxidants, reducing agents, acids, etc. Do not mix storage. Due to the imbalance of methyl ethyl, the product is unstable and not suitable for long-term storage.

Packing：200kg galvanized iron drum
