Abstract
The presence of cyclopentadiene in unsaturated C.sub.5 -hydrocarbons is often very undesirable. This is because cyclopentadiene is a poison to many of the catalysts used to polymerize C.sub.5 -hydrocarbon monomers. This invention reveals a process for reducing the concentration of cyclopentadiene in impure unsaturated C.sub.5 -hydrocarbons containing cyclopentadiene, comprising adding to said impure unsaturated C.sub.5 -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.
