Butanol is commonly used as a fuel in an internal combustion engine. A C4-hydrocarbon, butanol is used as a drop-in fuel in vehicles designed for use with gasoline without modification. There are about four isomers of butanol, but the most active commercialization work centres on isobutanol for blending with gasoline. Biobutanol can easily be blended, with gasoline with concentrations up to 11.5% by volume.
