2-ETHOXY-3,4-DIHYDRO-2H-PYRAN Usage And Synthesis
Chemical PropertiesColorless transparent liquid
UsesStabilizer, intermediate.
Synthesis Reference(s)The Journal of Organic Chemistry, 42, p. 282, 1977 DOI: 10.1021/jo00422a025
General DescriptionColorless liquid. Floats on water.
Reactivity ProfileEthers, such as 2-ETHOXY-3,4-DIHYDRO-2H-PYRAN 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.
HazardModerate fire risk.
Health HazardContact with liquid irritates eyes. Also irritates skin on prolonged contact.
Safety ProfileModerately toxic by skin contact. Mildly toxic by ingestion and inhalation. A skin and eye irritant. Flammable liquid when exposed to flame, sparks, and oxidizers. To fight fire, use dry chemical, foam, fog. When heated to decomposition it emits acrid smoke and irritating fumes
