Ethylene oligomerization catalyzed by Ind(2)Zr (OC6H4-p-Me)(2)/EtnAlCl3-n

The catalytic activities and selectivities of Ind(2)Zr(OC6H4-p-Me)(g) and E tnAlCl3-n(n=2, A; n= 1.5, B; n=1, C) as co-catalyst three binary catalyst s ystems on ethylene oligomerization have been studied at different reaction temperatures, aging temperatures and various reaction time. Under the same reaction condition the catalytic activities of three systems are in the fol lowing order: A >B >C. Under optimal reaction conditions, the activity of I nd(2)Zr (OC6H4-p-Me)(2)/A is 1 666 g/(g Zr . h), the selectivity Of C4-10 o lefins is 92.7% and the selectivity of alpha -C4-10 linear olefins is 86.0% .
