摘要: 用乙酸镍、2-乙基己酸镍、二乙基氯化铝、倍半乙基氯化铝等组成Ziegler-Natta催化剂催化丁烯齐聚.测定了二聚物组成,讨论了活性物种的形成过程,推导了反应机理.

关键词: Ziegler-Natta催化剂, 氢化镍活性物种, 丁烯齐聚, 反应机理

Abstract: The butenes are oligomerized with Ziegler-Natta catalysts composed of (CH3COO)2Ni, (CH3(CH2)3CH(C2H5)COO)2Ni, (C2H5)2AlCl and (C2H5)1.5AlCl1.5 repective-ly.The components in butene dimers are analysed.The course of the formation of active species is discussed.The reaction mechanism of butene oligomerization is deduced.

Key words: Ziegler-Natta catalyst, Nickel hydride active species, Butene oligomerization, Reaction mechanism
