Abstract

A process for the recovery of 2-methylbutanal from mixtures of isomeric aldehydes having 5 carbon atoms wherein the mixture is distilled in the presence of formaldehyde and an aldolization catalyst. The 2-methylbutanal obtained is useful as an intermediate for the preparation of various useful compounds, including the corresponding alcohol, amine, and acid.
