Properties：It is a colorless transparent liquid at room temperature, with slight pungent odor. Insoluble in water, soluble in alcohol, ketone, ester and other most organic solvents. Melting point: -43℃, Boiling point: 126.8℃, Flash point: 33℃, Density: 0.975g/ml.

Uses：Diethyl Carbonate is an aprotic, environment-friendly organic solvent, which is commonly used as a solvent for cellulose ethers, nitrocellulose, natural and synthetic resins. In the electronic industry, it is usually used as an electrolyte solvent for lithium-ion batteries and capacitors. Its electrochemical stability is good. It can improve the electrolyte's low temperature performance. As a common carbonation reagent, it can be used to synthesize ketones, tertiary alcohols and heterocyclic compounds, as well as the intermediate of pesticide pyrethrin and drug phenobarbital.

Storage：Keep it in a well-closed container and store in a cool, dry and well ventilated warehouse. Keep away from fire and heat source, and store separately from oxidants, reducing agents and acids.

Packing：200kg stainless steel drum or galvanized iron drum, 1200kg IBC drum, or ISO Tank.
