摘要
Immobilization of Ni(MeCN)(6)(BF4)(2) onto [Si]-MCM-41 and [Si,Al]-MCM-41 affords catalytic materials active in ethylene oligomerization in the presence of AIEt(3) as co-catalyst. The ethylene oligomerization reaction is performed in a batch reactor under 0.98 MPa of ethylene at 40 degrees C. The hybrid systems show activity for ethylene dimerization and trimerization, as well as for 1-butene isomerization. Both the amount of AIEt(3) and the presence of AI in the MCM-41 framework affect dramatically the targeted formation of 1-butene. (C) 2010 Elsevier B.V. All rights reserved.
