摘要
设计并合成了一种新型的后过渡金属铁络合物 { [(2 ArNC(Me) ) 2 C5H3N]FeCl2 } (Ar =2 ,4 C6 H4(CH3) 2 ) ,研究了该络合物 甲基铝氧烷 (MAO)催化乙烯低聚 ,讨论了低聚反应温度、Al Fe摩尔比、催化剂浓度、反应压力等对催化剂活性及反应速率的影响 .本催化剂的最大特点是活性高 (在 30℃ ,3 0MPa时活性可达 4 2 6× 10 8goligomer·molFe·h- 1 )、初速度大 ,动力学曲线为衰减型 .
A new late metal-transition complex {[(2-ArN=C(Me))(2)-C5H3N]FeCl2\Ar = 2,4-C6H4(CH3)(2)} was designed and synthesized. The behavior of ethylene oligomenization catalyzed by this complex with NIAO as cocatalyst has been studied. The effects of temperature, Al/Fe molar ratio, the concentration of catalyst and ethylene pressure on the catalytic activity and the rate of oligomerization were investigated. It was found that the catalyst is characterized by its high activity (the maximum is up to 4.25 x 10(8) g oligomer/molFe.h at 30degreesC, and 3.0 MPa) and high initial reaction rate. The kinetic curves obtained is of decay type.
