Abstract
The continuous preparation of aldehydes from olefins and synthesis gas by the use of a water-soluble catalyst system containing rhodium. The reaction takes place at 100 to 30,000 kPa and 90.degree. to 150.degree. C. The proportion of gaseous components in the liquids is 5 to 30% by volume, based on the total gaseous and liquid components, the volume ratio of aqueous to organic parts being 1:1 to 100:1. After completion of the reaction, the liquid components and the gaseous components are separated into a liquid phase and a gaseous phase, then the liquid phase is divided into aqueous and organic parts, separation taking place without previous cooling. The heat contained in the reaction product is either removed by water or steam, or is carried over to the hydroformylation products.
