The most commonly <br /> used oxygenates are <br /> methyl tertiary-butyl \� <br /> ether (MTBE) and <br /> ethanol. Other My- ( a� <br /> genates include ter- <br /> tiary-amyl methyl ether(TAME),ethyl tertiary-butyl ether <br /> (ETBE), diisopropyl ether(DIPS), tertiary-amyl ethyl ether <br /> (TAEE), tertiary-butyl alcohol (TBA), tertiary-amyl alcohol M`^ <br /> (TAA),and methanol. Some oxygenates have a long history <br /> of usage in gasoline. For example,ethanol has been used in 8 Study Gives Thumbs Up on Direct-Push Technology <br /> automotive fiel blends since the 1930s.Ethers,and primarily 9 The Eleven Myths about MTBE <br /> MTBE,have been used increasingly since the late 1970s.
