摘要 合成了3种PNP配体,与Ni(Ⅱ)形成催化剂,在助催化剂甲基铝氧烷(MAO)存在的条件下,催化乙烯齐聚.试验结果表明:镍系催化剂催化活性最高可达4.65×105g/(mol.h),α-烯烃选择性达76.40%.利用核磁共振氢谱、元素分析及质谱对配体及催化剂进行了结构表征. Three PNP ligands are synthesized,and they are compounded with Ni(II) to form three novel catalyst systems.The three catalysts are used along with methylaluminoxane(MAO) for the oligomerization of ethylene.The experimental results show that:the maximum catalytic activity of nickel-based catalysts can reach to 4.65×105 g/(mol·h),and their α-olefin selectivity can reach to 76.40%.The structure of the ligands and the catalysts are characterized by NMR,elemental analysis and mass spectrometry.
