研究了双茂基希夫碱稀土络合物 / Na H体系催化 1 ,5-己二烯的异构化反应。异构化反应生成 1 ,4-己二烯、2 ,4-己二烯、1 ,3-己二烯、亚甲基环戊烷和甲基环戊烯的混合物。同时研究了异构化反应中不同催化剂、反应温度、催化剂用量和时间对异构化速率及产品组成的影响。产物中线型产物与环状产物的比率取决于所用的催化剂及反应条件 The isomerization reaction of 1,5-hexadiene with double-Mauch Schiff’s base rare earth complex / NaH system was studied. The isomerization reaction produces a mixture of 1,4-hexadiene, 2,4-hexadiene, 1,3-hexadiene, methylenecyclopentane and methylcyclopentene. The effects of different catalysts, reaction temperature, catalyst amount and time on isomerization rate and product composition were also studied. The ratio of linear product to cyclic product in the product depends on the catalyst used and the reaction conditions used
