Cyclopentadienyl-arene titanatrane catalysts activated by methylaluminoxane (MAO) cocatalysts were studied for the trimerization of ethylene. The introduction of electron-rich multidentate ligands to the catalysts’ active sites resulted in good productivity and selectivity for ethylenetrimerization. Various amounts of MAO were tested, and methods of its introduction to the system were varied. It has
研究了由甲基铝氧烷 (MAO) 助催化剂活化的环戊二烯基-芳烃二氧化钛催化剂用于乙烯的三聚反应。将富电子多齿配体引入催化剂的活性位点可提高乙烯三聚反应的生产率和选择性。测试了各种数量的 MAO,并将其引入系统的方法各不相同。已经表明,催化剂与 MAO 的预烷基化提高了乙烯三聚的产率。还研究了反应温度和压力对 1-己烯生产率和选择性的影响。乙烯转化率大约是乙烯浓度的一级。1-己烯是在温和条件下生产的,可以通过较低温度的反应实现节能。
