摘　　要：采用双(正丁基环戊二烯基)二氯化锆/甲基铝氧烷(MAO)催化1–丁烯齐聚反应,考察了反应温度、n(Al)∶n(Zr)、助催化剂种类和反应时间对催化活性和齐聚产物分布的影响,确定了该催化剂催化1–丁烯齐聚反应的最佳工艺条件.通过减压蒸馏除去溶剂和二聚物后,利用1H NMR分析了剩余馏分的支化度(BI)为0.312,5,双键值为1.905mmol/g;20,℃时运动黏度为5.8,mm2/s,密度为0.822,8,g/cm3.除去溶剂和二聚物后的剩余馏分,适合作为柴油使用.Oligomerization of 1-butylene catalyzed by bis（n-butylcyclopentadienyl）zirconium dichloride/methylalumi- noxane was carried out. The effects of reaction temperature, A1/Zr molar ratio, different cocatalysts and reaction time on the catalytic activity and product distribution were investigated in depth to determine the optimal reaction conditions for oli- gomerization of 1-butylene. The structure of oligomer after the solvent and C8 dimer had been removed through distillation was characterized by 1H NMR. BI is 0.312 5. The amount of double bonds is 1.905 mmol/g. The kinetic viscosity is 5.8 mm2/s at 20℃, and the density is 0.822 8 g/cm3. The results show that 1-butylene oligomer without solvent and C8 dimer can be used as a diesel.
