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.
