    Abstract: The present invention relates to a method for producing n-butyraldehyde, 2-ethylhexyl alcohol and/or n-butanol from 1,3-butadiene-containing hydrocarbon streams, which comprises the following steps: a) reacting 1,3-butadiene with an amine of general formula (I) to form an amine of formula (II), whereby, in said formulae (I) and (II), the substituents R 1 and R 2 independently represent hydrogen or an appropriate organic radical from the group alkyl, alkenyl, cycloalkyl, alkoxyalkyl, aminoalkyl, monoalkylaminoalkyl, dialkylaminoalkyl, aryl and aralkyl, or R 1 and R 2 form a 3-to 7-membered heterocycle together with the nitrogen atom, which optionally comprises one or several double bonds and optionally one other heteroatom from the group N, O and S, in the presence of an amide of formula (III), in which R 3 and R 4 independently have the meaning indicated in the amines (I) and (II) for R 1 and R 2 and M represents an alkali metal; b) isomerizing the amine (II) to form an amine of formula (IV), in which R 1 and R 2 have the meaning indicated in the formulae (I) and (II) and c) releasing n-butyraldehyde as well as the amine of formula (I) by hydrolysis of said amine (IV) with water.
