摘要
主催化剂铬盐与配体、助催化剂组成的三元催化体系能够较高活性的催化乙烯四聚合成1-辛烯。主要研究了助催化剂种类、用量等对催化活性和1-辛烯选择性的影响,采用合适的助催化剂,1-辛烯的选择性达到70.1%,催化活性达到2.62×106 g/(mol Cr)·h。
New complexes were synthesized and used as cocatalysts for ethylene tetramerization in the pres ence of Cr（ Ⅲ）. The effect of the type and amount of cocatalyst on the studied,For the best cocatalyst,the 1-octene selectivity reached 70.1 % activity and 1-octene selectivity was and the activity was 2.62 ×106 g/（tool Cr） ·h.
