Process for separation of product resulting from hydroformylation |
| abstract |
A process is disclosed for preparing products such as 4-hydroxybutanal which comprises contacting unsaturated compounds such as allyl alcohol with carbon monoxide and hydrogen in the presence of a rhodium carbonyl-phosphine catalyst and an aromatic solvent. The solvent is an aromatic which causes a large density difference between the resulting aqueous phase and organic phase so that the soluble rhodium catalyst can be easily separated from the 4-hydroxybutanal product and starting material without appreciable loss of the metal. This allows for easy recycle of the catalyst solution. |
