摘要
在铬盐与配体、改性甲基铝氧烷组成的三元催化体系的基础上加入了给电子体组成四元催化体系,用于催化乙烯四聚合成1-辛烯。研究了给电子体种类、用量等对催化活性和1-辛烯选择性的影响,1-辛烯的选择性达到70.3%,催化活性达到4.79×106 g/(mol.h)。
New complexes were synthesized. They exhibited exceptionally high selectivity （up to 68%） towards 1-octene and activity for ethylene tetramerization in the presence of Cr （III） sources and m- methylaluminoxane. This paper studied the four-way catalytic system based on the three-way catalytic system, the electron donor added to the composition of quaternary catalyst system, mainly studied the electron donor, affect for activity and 1-oetene, selectivity.
