ABSTRACT OF THE DISCLOSURE A PROCESS FOR THE REMOVAL OF CYCLOPENTADIENE FROM UNSATURATED C5-HYDROCARBONS The presence of cyclopentadiene in unsaturated C5-hydrocarbons is often very undesirable. This is because cyclopentadiene is a poison to many of the catalysts used to polymerize C5-hydrocarbon monomers. This invention reveals a process for reducing the concentration of cyclopentadiene in impure unsaturated C5-hydrocarbons containing cyclopentadiene, comprising adding to said impure unsaturated C5-hydrocarbon (a) at least one member selected from the group consisting of trialkylaluminum compounds, dialkylaluminum hydride compounds, dialkylmagnesium compounds, and dialkylzinc compounds; and (b) an organonickel compound.
