【Abstract】 Ethylene oligomerization catalyzed by three binary systems of (bipy)CoCl\-2(A), (C\-6H\-5N=CC\-6G\-4\| o \|O)\-2Co(B), (acac)\-2Co(C) with EAO are studied. The effects of reaction temperature, Al/Co ratio and reaction time on catalytic activity and selectivity are investigated. The results show that three binary systems A, B, C are all active for ethylene oligomerization and in order A>B>C. The catalytic activity of (bipy)CoCl\-2/EAO(A) is \{2 411\} g/(g Co·h) and selectivity of C\+=\-\{4~10\} is 95.9% at 180 ℃.更多还原
