tert-AMYL METHYL ETHER Uses

Tert-Amyl methyl ether (CAS NO.994-05-8) is mostly used as an oxygenate to gasoline. It is added for three reasons: to increase octane enhancement, to replace banned tetraethyl lead, and to raise the oxygen content in gasoline. It is known that TAME in fuel reduces exhaust emissions of some volatile organic compounds.
