SELECTIVE HYDROGENATION OF CYCLOPENTADIENE TO FORM CYCLOPENTENE Abstract of the Disclosure There is disclosed a process for the preparation of cyclopentene which comprises selectively hydrogenating cyclopentadiene in a liquid phase by contacting cyclo- pentadiene with hydrogen in the presence of a hydrogena- tion catalyst comprising (1) a soluble nickel compound, (2) an organoaluminum compound or a lithium alkyl compound, and (3) at least one cocatalyst compound selected from the group consisting of H20; NH3; ROH where R is an alkyl or a halogenated alkyl radical containing from 1 to 20 carbon atoms; Image where R1, R2 and R3 may be hydrogen, or an alkyl radical containing from 1 to 6 carbon atoms; Image where R1, R2 and R3 may be hydrogen or halogen, or an alkyl radical containing from 1 to 6 carbon atoms; R10 R2 wherein R1 and R2 may be the same or different alkyl radicals con- taining from 1 to 6 carbon atoms; and R1CR2 wherein R1 may be alkyl or an aromatic radical containing from 1 to 8 carbon atoms and R2 may be hydrogen or an alkyl or aromatic hydrocarbon radical containing from 1 to 8 carbon atoms.
