【摘要】：石化工业最重要的产品是聚烯烃,其中大部分与聚乙烯相关,α-烯烃不仅是重要的共聚单体,也是精细化工的基本原料,乙烯工业发展程度代表了一个国家石化技术的水平。后过渡金属催化剂作为新型催化体系,能够高效催化乙烯齐聚和聚合,并且乙烯聚合可制备新型聚乙烯树脂。通过对配体的修饰,提高后过渡金属配合物催化活性,增加催化体系的热稳定性,仍然是当前催化剂设计的重要课题;实现对所得聚乙烯微观结构的控制,提高聚烯烃宏观性质是产业化的重要基础。本文基于配合物催化剂配体骨架设计为基础,集中讨论了铁、钴和镍配合物用于乙烯聚合和齐聚的性质比较;特别是集中展示了我们近期研究工作,综述了后过渡金属催化剂的新进展。
[Abstract]:The most important product of petrochemical industry is polyolefin, most of which is related to polyethylene. 伪 -olefin is not only an important comonomer, but also a basic raw material for fine chemical industry. The development of ethylene industry represents the level of petrochemical technology in a country. As a new catalytic system, post-transition metal catalysts can efficiently catalyze the oligomerization and polymerization of ethylene. By modifying the ligands, improving the catalytic activity of the post-transition metal complexes and increasing the thermal stability of the catalyst system, it is still an important issue in the design of catalysts. It is an important basis for industrialization to control the microstructure of the obtained polyethylene and improve the macroscopical properties of polyolefin. Based on the framework design of ligand of complex catalyst, iron is discussed in this paper. The properties of cobalt and nickel complexes for ethylene polymerization and oligomerization are compared, especially the recent research work and the new progress of post-transition metal catalysts are reviewed.
