Tertiary Amyl Methyl Ether (CH₃CH₂C(CH₃)₂-O-CH₃)

TAME can also be produced by the reaction of methanol with isoamylenes. The reaction conditions are similar to those used with MTBE, except the temperature is a little higher:

Similar to MTBE, TAME is used as gasoline additive for its high octane rating and its ability to reduce carbon monoxide and hydrocarbon exhaust emissions. Properties of oxygenates used as gasoline additives are shown in Table 1.1.
