Ethylene oligomerization over catalyst systems based on chromium(III) and aluminum coordination compounds

Vilms, A. I. / Babenko, I. A. / Belov, G. P.

Abstract The influence of the nature of a cocatalyst, a stabilizing ligand, and an introduced modifier on the behavior of the ethylene oligo- and polymerization reaction in the presence of the Cr(acac)3-AlR3-L-M catalyst system, where AlR3 is triethylaluminum (AlEt3), dichloroethylaluminum (AlEtCl2), or methylalumoxane (MAO); L is pyrrole (PyH) or bis(diphenylphosphino)cyclohexylamine ((Ph2P)2NCy); and M is tetrachloromethane (CCl4), has been studied. The maximal selectivity for hexene-1 has been found to be 86 wt %.
