Tertiary butyl alcohol molecular structure

The ethers and alcohols that are added to gasoline as oxygenates and octane boosters include methyl tertiary-butyl ether (MTBE), ethyl tertiary-butyl ether (ETBE), tertiary-amyl methyl ether (TAME), tertiary-amyl ethyl ether (TAEE), diisopropyl ether (DIPE), ethanol, methanol, isopropanol, and tertiary-butyl alcohol. Relevant properties of these compounds are listed in Table 1 and molecular structures are shown in Table 2. 

Catalysts containing niobia supported on various oxides have been the subject of considerable recent interest [1-4]. The molecular structures and reactivity of niobium oxides supported on alumina, titania, zirconia and silica have been intensively investigated over the last few years. Niobia supported on silica has been shown to be active for the dehydrogenation and dehydration of alcohols, photo-oxidation of propene and oxidative decomposition of methyl tertiary butyl ether. Titania supported niobia is active for the selective catalytic reduction (SCR) of NO by NH3.
