(CH3)3COC2H: An oxygenate blend stock formed by the catalytic etherification of isobutylene with ethanol.
Ethyl-t-butyl ether, an oxygen-containing fuel component used in reformulated gasoline. Commonly made from ethanol (ethyl alcohol) and isobutene.
Ethyl Tertiary Butly Ether. An aliphatic ether similar to MTBE. This fuel oxygenate is manufactured by reacting isobutylene with ethanol having high octane and low volatility characteristics ETBE can be added to gasoline up to a level of approximately 17 percent by volume. ETBE is used as an oxygenate in some reformulated gasolines.
