n. a flammable alcohol derived from butanes and used for solvents [syn: butyl alcohol]


Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C H OH, which occurs in four isomeric structures, from a straight-chain primary alcohol to a branched-chain tertiary alcohol; all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, n-BuOH, and i-BuOH). These are n-butanol, 2-butanol, tert-butanol, and isobutanol. Butanol is primarily used as a solvent, as an intermediate in chemical synthesis, and as a fuel. It is sometimes also called biobutanol when produced biologically.
