tert-Amyl methyl ether (TAME) is a volatile, low viscosity clear liquid at room temperature with an ether odour. TAME is flammable and can form explosive mixtures with air. It is slightly soluble in water and fully miscible with ethers and alcohol and with most organic solvents including hydrocarbons.
TAME may be prepared by reacting isoamylenes in a mixed C5 stream with methanol in the presence of an acidic ion-exchange resin catalyst such as sulfonated styrene linked with divinyl benzene.
The most quantity produced worldwide is used as an oxygenate to gasoline. It is added both to increase octane enhancement to replace banned tetraethyl lead and to raise the oxygen content in gasoline.
TAME is a non-chlorinated process solvent in chemical industry.
tert-Amyl methyl ether is used as a paraffin-removing agent alone or in combination with other solvents.
