tert-Butyl methyl ether Chemical Properties,Uses,Production

Chemical Properties

Clear colorless liquid

Chemical Properties

Methyl-tert-butyl ether is a colorless liquid.

Uses

Suitable for HPLC, spectrophotometry, environmental testing

Uses

Suitable for pesticide residue analysis

Uses

Octane booster in gasoline. Chromatographic eluent especially in HPLC.

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.

Hazard

Slightly toxic by ingestion and inhalation. Flammable when exposed to heat or flame. Upper respiratory tract irritant and kidney damage. Questionable carcinogen.

Health Hazard

INHALATION: May cause dizziness or suffocation. Contact may irritate or burn eyes or skin. May be harmful if swallowed.

Industrial uses

Methyl tert-butyl ether (MTBE) is used as an octane enhancer in gasoline. EPA regulations allow up to 2.7 wt.% oxygen in gasoline which allows 15 vol.% MTBE in gasoline. Other alkyl ethers can also be blended into gasoline up to the 2.7 wt% oxygen requirement. The stability of MTBE to oxidation and peroxide formation gives this unsymmetrical ether an advantage over other ethers in various extraction and reaction solvent applications.

Safety Profile

Poison by intravenous route. Slightly toxic by ingestion and inhalation. Flammable when exposed to heat or flame. When heated to decomposition it emits acrid smoke and irritating fumes. See also ETHERS.

Potential Exposure

Used as an organic solvent; as an octane booster in unleaded gasolines; in making other chemicals; and in medicine to dissolve gall stones

Shipping

UN2398 Methyl tert-butyl ether, Hazard Class: 3; Labels: 3-Flammable liquid.

Purification Methods

Purify as for n-butyl methyl ether. [Beilstein 1 IV 1615.]

Incompatibilities

May form explosive mixture with air. May be able to form unstable peroxides. Much less likely to form peroxides than other ethers. Incompatible with strong acids. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. May accumulate static electrical charges, and cause ignition of its vapors.

Waste Disposal

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
