These butanol isomers, due to their different structures, have somewhat different melting and boiling points. All are moderately miscible in [[Water|water]] and used as a base for perfumes. For the purposes of [[Distillation|distillation]], butanol is considered to be a [[Fusel_oils|fusel oil]]. Like most alcohols, they are poisonous.
