Abstract
An improved hydroformylation process for preparing aldehydes by reacting olefins with synthesis gas (H.sub.2 and CO) under heating and pressure is disclosed. The hydroformylation is carried out in the presence of a platinum catalyst, and assistant composed of a halide of a metal of the group IVb of the Periodic Table and a reaction promotor composed of a specific bidentate ligand of the formula R.sub.2 X-Z-Y-Z-X-R'.sub.2. In this reaction, the platinum catalyst exerts a high activity, and an aldehyde mixture containing a linear isomer at a very high ratio of content is obtained as a product.
