Appearance:Dihydro-2h-pyran appears as a clear colorless liquid with an ethereal odor. Less dense than water. Vapors heavier than air.
Density:0.922 g/cm3 @ Temp: 19 °C
Melting Point:-70 °C
Boiling Point:86 °C
Flash Point:0° F (NFPA, 2010)
Refractive Index:n 20/D 1.440(lit.)
Water Solubility:H2O: 7.7g/l
Storage Conditions:Flammables area
Vapor Pressure:77.8 hPa (20 °C)
Vapor Density:2.9 (vs air)
Toxicity:LD50 orally in Rabbit: > 4000 mg/kg
Explosive limit:1.1-13.8%(V)
Air and Water Reactions:Highly flammable. Slightly soluble in water.
Reactive Group:Ethers
Reactivity Alerts:Highly Flammable
Reactivity Profile:Ethers, such as 2,3-DIHYDROPYRAN, 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.
