ABSTRACT OF THE DISCLOSURE Distillation residues from the hydroformylation of propene are worked up by adding from 1 to 2 moles, based on the acid content, of n- butanol and/or isobutanol, and carrying out esterification in the presence of a catalytic amount of a sulphonic acid and at a temperature of 50 to 200 C, water formed during the reaction being separated off. The ester- ification product is further processed in known manner, for example by dis- tillation and hydrogenation to give a product consisting predominantly of n-butanol, isobutanol and 2-ethylhexanol.
