【摘要】 以1,1,1,5,5,5-六氟代戊二酮合镍（简称Ni（Hfacac）₂）和二异丁基氢化铝（简称（i-Bu）₂AlH）为催化剂使丙烯齐聚,丙烯二聚物的线性率为75—80％,研究了A1/Ni[（i-Bu）₂AlH/Ni（Hfacac）₂摩尔比]、反应温度等因素对催化剂的活性、二聚物的线性率和二聚物的组成分布的影响,讨论了本反应体系的反应机理。更多还原

【Abstract】 Propylenc was oligomerized by the complex catalyst prepared in situ from the nickel salt of 1, 1, 1 ,5,5,5-hexafluoropentane-2,4-dione and diisobutyl aluminum hydride. The linearity of the propylene dimers is in the range of 75-80%. It was observed that the Al/Ni (Molar ratio) value and the reaction temperature exerted evident influence on the activity of the catalyst and the linearity of propylene dimers. The reaction mechanism of the catalyst system has been discussed preliminarily.更多还原
