Butanol - Wikipedia
Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C 4 H 9 OH, which occurs in five isomeric structures (four structural isomers), from a straight-chain primary alcohol to a branched-chain tertiary alcohol; [1] all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, sec-BuOH, i-BuO...
1-Butanol - Wikipedia
1-Butanol, also known as butan-1-ol or n-butanol, is a primary alcohol with the chemical formula C 4 H 9 OH and a linear structure. Isomers of 1-butanol are isobutanol, butan-2-ol and tert -butanol. The unmodified term butanol usually refers to the straight chain isomer.
