Butanol is a type of alcohol that has four carbon atoms in its structure. It is commonly used as a solvent in various industrial applications and can also be found in some personal care products. Butanol exists in several isomeric forms, including n-butanol, isobutanol, sec-butanol, and tert-butanol, each with unique properties and uses. This compound is produced through different methods, including fermentation and petrochemical processes. In addition to its industrial uses, butanol can serve as a fuel additive and is being explored as a potential biofuel due to its favorable energy content and lower toxicity compared to other alcohols.
