摘　　要：合成了一种新型的α-二亚胺合镍氯化物。以MAO为助催化剂,考察了该络合物催化乙烯齐聚反应,分析了齐聚反应温度、Al与Ni物质的量比对催化剂活性和产物碳数分布的影响。结果表明:在催化剂浓度为3×10^(-4)mol·L^(-1),反应压力为0.1MPa,反应时间为30min,反应温度为35～40℃,n(Al)/n(Ni)为300的条件下,该络合物催化乙烯齐聚具有较高的活性;产物烯烃中直链α-烯烃含量较高,碳数分布较低。该络合物在工业上具有应用价值。A novel aaaa- diimine nickel chloride was synthesized. The behavior of ethylene oligomerization catalyzed by this complex with MAO as cocatalyst has been studied. The result shows that when the catalyst concentration is 3×10-4 mol · L-1 , the reaction pressure is 0. 1 Mpa, the reaction time is 30 min, the reaction temperature is 35-40 ℃ and n(Al)/n(Ni) is 300, the complex has higher activity on ethylene oligomerization. The content of liner α-olefin in product is higher and the distribution of carbon is lower. The complex is applicable in industry.
