description | The present invention pertains to a method for recovering a selective homogeneous hydrogenation catalyst and a method for reusing the recovered selective homogeneous hydrogenation catalyst. The method for recovering a selective homogeneous hydrogenation catalyst comprises: a step for synthesizing cyclododecene by selectively hydrogenating a first reaction solution containing cyclododecatriene, triphenylphosphine, formaldehyde, and ruthenium chloride, wherein a selective homogeneous hydrogenation catalyst is prepared during the selective hydrogenation reaction from the triphenylphosphine, formaldehyde, and ruthenium chloride to synthesize the cyclododecene; and a step for distilling and separating unreacted cyclododecatriene and cyclododecadiene, as well as the product cyclododecene, from a second reaction solution in which the cyclododecene synthesis has been completed, and recovering the selective homogeneous hydrogenation catalyst. |
