tert-Butyl methyl ether Usage And Synthesis |
Chemical Properties | Clear colorless liquid |
Usage | Suitable for HPLC, spectrophotometry, environmental testing |
Usage | Suitable for pesticide residue analysis |
General Description | A colorless liquid with a distinctive anesthetic-like odor. Vapors are heavier than air and narcotic. Boiling point 131°F. Flash point 18°F. Less dense than water and miscible in water. Used as a octane booster in gasoline. |
Air & Water Reactions | Highly flammable. Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979. p.151-154, 164]. A mixture of liquid air and diethyl ether exploded spontaneously [MCA Case History 616. 1960]. |
Reactivity Profile | Ethers, such as tert-Butyl methyl ether, 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. |
Health Hazard | INHALATION: May cause dizziness or suffocation. Contact may irritate or burn eyes or skin. May be harmful if swallowed. |
