| 摘 要： | 采用溶剂热法合成二维钴金属有机配位聚合物（CoBTC），在不同温度下真空活化得到系列CoBTC催化剂。采用热重（thermogravimetric，TG）分析、X射线衍射（X-ray diffraction，XRD）分析、傅里叶变换红外光谱（Fourier transform infrared spectroscopy，FTIR）分析、扫描电子显微镜（scanning electron microscope，SEM）等表征手段对CoBTC催化材料和催化剂进行表征，并将其应用于乙烯选择性齐聚反应，考察反应体系的n(Al)/n(Co)、反应压力、助催化剂种类对催化性能的影响。结果表明，CoBTC催化剂的乙烯齐聚活性达到3.73×105 g•mol-1(Co)•h-1，C8的选择性高达98.68%. |

| Abstract： | A two-dimensional cobalt metal organic coordination polymer (CoBTC) was synthesized using a solvothermal method and evacuated under different temperatures to generate a series of CoBTC catalysts for ethylene selective oligomerization. The physicochemical properties of the CoBTC material were characterized by several techniques including thermogravimetric (TG), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM). The effects of oligomerization reaction parameters, including n(Al)/n(Co), pressure and cocatalysts, on the catalytic activities and oligomers distribution were investigated. Results demonstrated that the CoBTC catalytsts exhibited the optimal ethylene oligomerization activity of 3.73×105 g•mol-1(Co) •h-1 with C8 selectivity of 98.68%. |
