    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.
