摘要
综述了近年来国内外乙烯三聚和乙烯四聚催化体系的研究进展并对催化体系的组成、活性、成本及其对产物的选择性进行了分析。铬系催化剂是乙烯选择性齐聚催化剂研究的重点,主要包括带有含磷、氮和硫配位原子的三齿配体和双磷胺配体的配合物。同时介绍了乙烯三聚、四聚的反应机理,以作为乙烯选择性齐聚研究时的参考。
The advances of catalysts used for ethylene tetramerization and trimerization at home and abroad were summarized. The composition for catalysts, activity, cost and selectivity for products were analyzed. Chromium -based catalysts were the keystone for ethylene selective oligomerization. It mainly included chromium complexes bearing tridentate ligands with ligating atoms of phosphorus, nitrogen and sulfur, and diphosphinoamine ligands, Mechanisms of trimerization and tetramerization for ethylene were also introduced.
