Description

TAME, or tert-Amyl methyl ether, is an organic compound with the expanded chemical formula CH₃-CH₂-C(CH₃)₂-O-CH₃ (short: C₆H₁₄O) classified as an ether. It is produced by the catalytic reaction (etherification) of isoamylenes—primarily 2-methyl-1-butene and 2-methyl-2-butene—with methanol. The process is typically catalyzed by an ion-exchange resin in the liquid phase according to the reaction:

Isoamylene (either 2-methyl-1-butene or 2-methyl-2-butene) + Methanol → TAME

TAME is used as a fuel oxygenate added to gasoline to increase octane rating and improve combustion efficiency, which helps reduce harmful emissions such as carbon monoxide and hydrocarbons, as well as an environmentally friendly solvent in organic synthesis due to its high boiling point and stability.
