Summary:An improvement in the process for the continuous manufacture of an aldehyde by reaction of an olefin with carbon monoxide and hydrogen in the presence of a rhodium catalyst at an elevated temperature and pressure followed by distillative separation of the non-converted feedstocks and low boiling components of the reaction mixture, the improvement residing in employing a carbon monoxide/hydrogen mixture containing 2-20 ppm sulfur and recycling residual rhodium compounds, both dissolved and suspended in the distillation residue, to the reaction zone.
