摘要
以CrCl3(THF)3作为金属活性中心,烷基铝为助催化剂,研究评价了反应体系中Cr离子的浓度、N/Cr摩尔比以及Al/Cr摩尔比对催化剂性能的影响。研究结果表明:该催化剂具有较高的乙烯三聚催化活性,催化剂活性可达2.48×105g产品/(gCr.h),1-己烯正构率大于98.5%。
The effects of concentration of Cr ion, molar ratio of N to Cr, and molar ratio of Al to Cr, etc. on catalyst properties were studied with CrC1l3 (THF)3 as main catalyst and alkyl aluminum as co -catalyst. The results showed that this kind of catalyst had high catalytic activity on ethylene trimerization to 1 - hexene. The catalytic activity reached 2.48×10^5 g/(gCr .h) and the molar ratio of 1 -C6- to C6 was greater than 98.5%.
