2-Ethyl-1-butanol (IUPAC name) is an organic chemical compound. It can be used to facilitate the separation of ethanol from water, which form an azeotrope that otherwise limits the maximum ethanol concentration.[3]

Reactions[edit]

2-Ethyl-1-butanol is manufactured industrially by the aldol condensation of acetaldehyde and butyraldehyde.[4]
