摘要

制备了硅胶负载型2

6-二亚胺基吡啶铁系齐聚催化剂。考察了不同负载温度

聚合中乙烯加压方式

催化剂的加入量以及丙烯对乙烯齐聚活性和α-烯烃分布的影响。结果表明

低温负载有利于催化剂活性提高

分段加压可以使催化剂的活性周期增加

聚合温度平稳

单位助催化剂MAO转化的乙烯量增加

而α-烯烃的选择性基本不变。Fe催化剂负载后

以单位助催化剂MAO计算的乙烯转化率提高。增加催化剂的量后

单位助催化剂MAO转化的乙烯量增加。在乙烯齐聚中加入少量丙烯催化剂的活性降低

α-烯烃分布向低碳方向移动。

Abstract

The 2

6-Bis(imino) - Pyridyl Ligands iron-based catalysts supported on SiO

were prepared. The catalytic activity and selectivity of the system in ethylene oligomerization were studied under different supported temperature

reaction pressures

the amount of catalysts and propylene.The results showed that low supported temperature is good to catalytic activities. The activity cycle increased and polymerization temperature was stable

and ethylene conversion of unit cocatalyst methylaluminoxane(MAO) increased when using section pressure mode. But the selectivities of α-olefins almost invariant. The activities calculated by unit MAO increased after SiO

-supported. With the increase of catalysts

the ethylene conversion of unit MAO increases. The activities decrease when adding propylene and more low-molecular-weight products were produced.
