tert-Butyl methyl ether Chemical Properties,Uses,Production

Chemical Properties

Clear colorless liquid

Uses

Suitable for HPLC, spectrophotometry, environmental testing

Uses

Suitable for pesticide residue analysis

Definition

ChEBI: An ether having methyl and tert-butyl as the two alkyl components.

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.
