Hydroformylation process using a cobalt-based catalyst in a nonaqueous ionic liquid |
| abstract |
The invention relates to a process for the hydroformylation of olefinically unsaturated compounds by means of a cobalt-based catalyst, used in a nonaqueous ionic liquid, which liquid is at a temperature below 1000°C and comprises at least one cation Q<SUP>+</SUP> and at least one anion A<SUP>_</SUP>, wherein said process comprises at least one step of reaction under pressure and at least one step of phase separation by settling out, in which process the recycling of the catalyst is improved - through the use of a ligand chosen from Lewis bases, more particularly pyridine derivatives, - and simultaneously through the addition of this ligand in a post-reaction step. Following this process, the organic phase containing the reaction products can be recovered and the ionic liquid phase containing the catalyst can be recycled to the hydroformylation reactor. |
