Abstract

Process for preparing isononanoic acid proceeding from 2-ethylhexanol, characterized in that (a) 2-ethylhexanol is dehydrated to octene in the presence of a catalyst; (b) the octene obtained in step a) is reacted in the presence of a transition metal compound of group VIII of the periodic table of the elements with carbon monoxide and hydrogen to give isononanal; and (c) the isononanal obtained in step b) is oxidized to isononanoic acid.
