合成了新型络合物氯化2-乙酰基-6-(2-甲基苯亚胺基)乙基吡啶铁,探讨了它与甲基铝氧烷(MAO)共同组成的二元催化体系催化乙烯齐聚的性能。在60℃、2.0 MPa、n(Al)/n(Fe)=1500、主催化剂浓度为20μmol/l的条件下,催化剂活性高达2.03×107g/(mol.h),且丁烯-1选择性小于10%,己烯-1选择性大于20%,辛烯-1选择性大于18%。
A new complex of 2-acetyl-6- (2-methylbenzimido) ethylpyridine chloride was synthesized and its catalytic activity was discussed in the presence of a binary catalytic system consisting of methylaluminoxane (MAO) Ethylene oligomerization performance. Under the conditions of 60 ℃, 2.0 MPa, n (Al) / n (Fe) = 1500 and the main catalyst concentration of 20μmol / l, the catalyst activity reached as high as 2.03 × 107g / (mol.h) Less than 10%, greater than 20% hexene-1 selectivity and greater than 18% octene-1 selectivity.
