| titleOfInvention | Method for preparing aldehyde compound by olefin two-phase hydroformylation |
| abstract | The invention discloses olefin two-phase hydroformylationThe invention relates to a method for preparing aldehyde compound, belonging to the technical field of aldehyde synthesis, which comprises the steps of forming a catalytic system by using a water-soluble phosphine ligand and a rhodium catalyst, and using cheap and easily-obtained large-polarity formamide, N-methylformamide, N-dimethylformamide and the like as solvents to enable olefin and H to react 2 The solubility of olefin in a large-polarity organic solvent is far greater than that of olefin in water, so that the reaction activity is greatly improved compared with that of water-oil two-phase hydroformylation; after the reaction is finished, the system automatically separates phases, the upper layer is a low-polarity product aldehyde, the lower layer is a high-polarity solvent phase, the water-soluble catalyst is dissolved in the high-polarity solvent phase, and the catalyst can be recycled for multiple times through liquid separation operation; the method has the characteristics of mild reaction conditions, high selectivity and high conversion rate, and the catalyst can be circulated for a long time and has excellent industrial application prospect. |
