Abstract
In catalytic hydroformylation of an olefin with hydrogen and carbon monoxide, when a platinum-phosphine complex is used as a catalyst and a compound of tin and an element of the group VIB of the Periodic Table is used as a promotor, condensation of the formed aldehyde as a side reaction is controlled and the intended aldehyde can be obtained in a high yield.

A process for the preparation of aldehydes by hydroformylation of olefins, which comprises reacting an olefin with hydrogen and carbon monoxide in the presence of a platinum-phosphine complex catalyst, wherein a compound represented by the following general formula:
- SnM.sub.m
- wherein M stands for an element of the group VIB of the Periodic Table and m is 1 or 2, or
- SnSO.sub.4 is used as a promotor for said reaction wherein an aldehyde is formed by hydroformylation of said olefin.
