    摘要: A process and catalyst for isomerizing olefins are disclosed. The process and catalyst are particularly useful for isomerizing alkenyl bridged ring compounds to the corresponding alkyladiene bridged ring compounds. The isomerization catalyst comprises an oxygen treated mixture of an alkali metal on a calcined support having a surface area of 125 to 195 m2/g. The catalyst is particularly useful for isomerizing 5-vinyl-2-norbornene to 5-ethylidiene-2-norbornene. The catalyst is very active and highly selective and resistant to catalyst poisons. The process contacts the catalyst with an alkenyl bridged ring compound and yields the corresponding alkyladiene bridged ring compound.

    烯桥连环化合物。 异构化催化剂包含在经煅烧载体上的氧化处理的碱金属混合物,其表面积为125至195m 2 / g。 该催化剂特别适用于将5-乙烯基-2-降冰片烯异构化为5-亚乙基-2-降冰片烯。 该催化剂非常活跃,选择性高,对催化剂毒物具有抗性。 该方法用烯基桥连环化合物与催化剂接触并产生相应的烷基二烯桥环化合物。
