Hazard InformationBack Directory
[General Description]

Colorless liquid. Floats on water.
[Reactivity Profile]

Ethers, such as ETHOXYDIHYDROPYRAN can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.
[Hazard]

Moderate fire risk.
[Health Hazard]

Contact with liquid irritates eyes. Also irritates skin on prolonged contact.
