Isobutanol is an organic compound. Its isomers include n-butanol, 2-butanol, and tert-butanol. Isobutanol is produced by the carbonylation of propylene. Isobutanol is also produced naturally during the fermentation of carbohydrates and may also be a byproduct of the decay process of organic matter. Isobutanol, along with other low molecular weight alcohols can also be produced by some engineered microorganisms such as corynebacterium. It is useful in organic synthesis, as a chemical intermediate and as a solvent in coating applications. Isobutanol is similar in property to n-butyl alcohol and may be used as a supplement or replacement for n-butyl alcohol in many applications. Isobutanol could possibly serve as an alternative to gasoline to fuel combustion engines.
