摘要
设计并合成了一系列稠环芳基取代的菲咯啉亚胺类配体,用于铁系催化剂催化乙烯齐聚,通过配体修饰考察了稠环芳基的位阻和电子效应对催化剂性能的影响,并考察了反应条件对催化剂性能的影响.结果表明:稠环芳基取代的菲咯啉亚胺类配体在铁系催化剂催化乙烯齐聚中性能优良,活性达13.60×106 g/(mol·h),α-烯烃选择性为92%,C14与C12摩尔比(K值)为0.49;通过条件优化,该类催化剂活性最高能达到17.39×106 g/(mol·h),α-烯烃选择性达96%,K值为0.63.
Abstract
A series of imino-phenanthroline ligands bearing polycyclic aryl were synthesized and used for ethylene oligomerization over Fe catalysts.The effects of steric and electronic effect of polycyclic aryl on catalytic performance were investigated by ligand modification,and the influence of reaction conditions on catalytic behavior were studied.The results show that those polycyclic aryl-substituted phenanthroline imine ligands exhibit excellent catalytic performance in iron-catalyzed ethylene oligomerization,with an activity of up to 13.60×106 g/(mol·h),an α-olefin selectivity of 92%,and a molar ratio of C14 to C12(K-value)of 0.49.After optimization for reaction conditions,the activity of the catalysts could reach as high as 17.39×106 g/(mol·h),in combination with 96%of α-olefin selectivity and the K-value of 0.63.
