    摘要: The disclosed is about a hydroformylation reaction of a cyclic olefin in the presence of a rhodium catalyst, and specifically about recovering the rhodium catalyst. After the cyclic olefin is hydroformylated by the rhodium catalyst, the product solution is added an extraction liquid including a cycloalkyl alcohol and separated into two layers. The upper layer is substantially made up of the rhodium catalyst solution, and the lower layer is substantially made up of the cycloalkyl aldehyde and the extraction solution including cycloalkyl alcohol.

The optical film with low or zero birefringence includes a plurality of birefringence films, and the plurality of birefringence films is overlapped with the long axes perpendicular to each other. A sum of the refractive indices of the overlapped birefringence films in an x direction is equal to that in a y direction. The placement of the birefringence films in the optical film with low or zero birefringence can solve the problem that optical polymer cannot be applied to optical parts due to the birefringence of optical polymer.
