乙烯选择性齐聚催化体系的研究进展

Research advance of catalytic systems for selective ethylene oligomerization

综述了近年来乙烯选择性二聚、三聚、四聚等催化体系的最新进展。研究表明:乙烯选择性齐聚催化剂中配体的配位原子上取代基的空间位阻效应和配位原子的电子效应是影响目标产物的选择性和催化活性的主要因素,设计合成新型的配体对提高乙烯选择性催化体系活性和1-辛烯选择性工业化的生产至关重要。

Recent progress of selective ethytene oligomerization catalytic systems was summarized. Se-lective ethylene dimerization, trimerization and tetramerization systems were introduced. Steric effect of the substituents and electronic effect on coordination atoms of ethylene selectivity oligomerization catalyst ligand are the main factors that affect the target product selectivity and catalytic activity. The design and synthesis of novel ligands are crucial for the improvement of the selectivities of ethylene ol- igomerization and the industrialization of ethylene tetramerization process to produce 1-octene.
