Figure 9.15. MTBE, methyl t-butyl ether, a common octane booster in gasoline, has an octane number of 116. Other boosters are ETBE (ethyl t-butyl ether RON = 118) and TAME (t-amyl methyl ether RON = 111).

The additives used in oxygenated gasoline are alcohols and ethers, the most common of which are ethanol (ethyl alcohol grain alcohol) and methyl t-butyl ether (MTBE). Two less commonly used additives are ethyl t-butyl ether (ETBE) and t-amyl methyl ether (TAME). The chemical structures of these four additives are shown in the diagram on page 24.

In the United States, passage of the 1990 Clean Air Act Amendments (CAAAs) led to the development of Federal programs that required oxygen-containing compounds be blended in gasoline to reduce carbon monoxide emissions. Examples of compounds used as oxygenates are methyl t-butyl ether (MTBE), ethanol (EtOH), ethyl t-butyl ether (ETBE), t-amyl methyl ether... 

Such catalyst resins are now used in the production of many industrially important materials, including solvents such as MIBK, oxygenate additives such as TAME (t-amyl methyl ether), hydrogen peroxide and 1,2 propanediol. In contrast, there is much less use of catalytic ion exchange resins in the commercial production of fine chemicals. The reasons for this might include selectivity aspects, the availability of resins in a shape that is well suited for large reactors and a lack of knowledge with respect to the accessibility and stability of the active sites. The importance and the scope of uses of such catalysts are often limited by diffusional issues and problems of mechanical and thermal stability.
