The invention relates to a process for separating dibutenes into an n-octene-containing fraction and a dimethylhexene-containing fraction. The fractions can be processed further separately to the corresponding C9 carboxylic acids and C9 alcohols (isononanols). Successor products of the C9 carboxylic acids are, for example, vinyl esters. Successor products of the C9 alcohols are plasticizers.
