The disclosed is about a hydroformylation of a cyclic olefin with rhodium catalyst, and specifically about the recovering of the rhodium catalyst. Aldehyde and the cyclic olefin are added into a rhodium catalyst solution to process a hydroformylation, thereby forming the product cycloalkyl aldehyde. Afterwards, the result is divided into two layers. The upper layer is substantially rhodium catalyst solution, and the lower layer is substantially cycloalkyl aldehyde and the aldehyde. After separation, the upper layer is reserved to process next hydroformylation reaction with newly added cyclic olefin.
