Butanol

Butanol

Butanol is a higher alcohol with a four carbon atoms and a general formula of C₄H₁₀O. There are four different isomeric structures for butanol:

butan-1-ol CH3-CH2-CH2-CH2-OH

butan-2-ol CH3-CH2-CH(OH)-CH3

sec-butanol CH3-CH-CH3 | CH2OH

OH | tert-butanol CH3-C-CH3 | CH3

These butanol isomers, due to their different structures, have somewhat different melting and boiling points. All are moderately miscible in water and used as a base for perfumes. Like all alcohols, they are poisonous.
