The present invention relates to a hydroformylation method of olefins having excellent reaction selectivity. As a hydroformylation reaction apparatus, a high pressure reaction is possible and a loop type reactor capable of increasing reaction efficiency is used, and the activity is relatively high as a hydroformylation reaction catalyst. It is relatively free of catalyst deactivation by using low hetero catalysts, so the CO partial pressure can be freely controlled, N / I selectivity can be adjusted, and product and catalyst can be separated easily by filter. It does not need to have an excellent effect. |
