    摘要: A multi-stage process for isomerizing olefin compounds to the corresponding product olefin compounds is provided. The isomerization catalyst comprises an oxygen treated mixture of an alkali metal on a calcined support. The multi-stage process is particularly useful for isomerizing 5-vinyl-2-norbornene to 5-ethylidiene-2-norbornene. The catalyst is very active and highly selective and resistent to catalyst poisons. The process contacts the catalyst with an isomerizable olefin in at least two reaction stages to yield the corresponding product olefin compound. The reaction stages differ in temperature, catalyst activity or both.

    摘要: A process is disclosed for the preparation of 5alkylidenenorbornene-2 for use as an important component of EPDM rubber. This product is obtained by the isomerization of 5alkenylnorbornene-2 which is carried out in the presence of a composite catalyst having increased activity and tending to suppress the formation of undesirable side products. The composite catalyst is essentially comprised of a cyclopentadienyl cobalt compound, an organometallic compound and an activating agent, and has been found peculiarly effective in the isomerization reaction.
