    摘要: A hydrogenation catalyst system is provided. The catalyst system includes a metal complex of Formula (I), an organic lithium compound and an organic compound having a cyclic structure including at least one double bond. In Formula (I), M is transition metals. R1, R2, R3, R4 and R5 are the same or different, including hydrogen, C1-8 alkyl, and C1-8 alkoxy, or two of R1, R2, R3, R4 and R5 are linked together to form a ring. X1, X2 and X3 are a cyclic group, hydrogen, chlorine, bromine, alkyl or alkoxy, wherein when one of X1, X2 and X3 is a cyclic group, and the others are the same or different, including hydrogen, chlorine, bromine, alkyl or alkoxy. The invention also provides a selective hydrogenation process utilizing the catalyst system.

    摘要: 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.
