摘　　要：按照多齿杂原子配体(含氧、氮、磷、硫以及混合氮磷和混合氮硫多齿配体)的分类,综述了不同铬系乙烯三聚催化剂体系的组成、活性及对1-己烯的总选择性,展望了乙烯三聚催化剂的商业应用前景。研究表明,配体结构对乙烯三聚活性和选择性的影响最为显著。Cr(Ⅲ)SNS催化体系因其原料价格低廉,合成收率高,活化所需甲基铝氧烷(MAO)用量低,同时具有对1-己烯的选择性和活性都很高的性能,将有很好的工业应用价值。According to the various multidentate heteroatomic ligands（based oxygen,nitrogen,phosphorus,mixed N and P,mixed N and S donors）,composition,activity and overall selectivity to 1-hexene of chromium-based trimerization catalysts were reviewed.Commercial application foreground of these catalyst systems was also expected.The effect of ligand structure on activity and selectivity for ethylene trimerization was the most predominant.The SNS ligands were prepared using inexpensive reagents and gave the corresponding complexes in high yields.Due to the inexpensive ligands coupled with low MAO requirements,high activity and selectivity of these systems,it has positive implication for a commercial process.
