Method for producing aldehydes |
| abstract |
(57) [Summary] [Object] To provide a method for recovering unreacted olefin from a reaction solution containing a rhodium catalyst without substantially deactivating the catalyst. A method for producing aldehydes, comprising reacting an olefin with carbon monoxide and hydrogen in the presence of a rhodium catalyst having an organophosphorus compound as a ligand in a hydroformylation reaction region, comprising: The reaction liquid containing the unreacted olefin, the aldehyde product and the catalyst taken out is brought into countercurrent contact with carbon monoxide and hydrogen to separate and recover the unreacted olefin from the reaction liquid without substantially deactivating the rhodium catalyst. , Supplying unreacted olefin recovered with carbon monoxide and hydrogen to a hydroformylation reaction zone. |
