METHOD OF SEPARATING PENTENE-2 FROM A C5 CUT CONTAINING PENTENE-2 AND PENTENE-1 BY SELECTIVE OLIGOMERIZATION OF PENTENE-1
The present invention describes a method of separating pentene-2 from a C5 cut containing pentene-2 and pentene-1 by selective oligomerization of pentene-1 to dimers having a branching index less than or equal to 1. Optional additional steps make it possible to separate 2-methyl-2-butene, 2-methyl-1-butene, n-pentane, iso-pentane, pentadienes as well as traces of acetylene hydrocarbons optionally present in the C5 feedstock.

METHOD OF SEPARATING BUTENE-2 FROM A C4 CUT CONTAINING BUTENE-2 AND BUTENE-1 BY SELECTIVE OLIGOMERIZATION OF BUTENE-1
The present invention describes a method of separating butene-2 from a C4 cut containing butene-2 and butene-1 by selective oligomerization of butene-1 to predominantly linear oligomers. Optional additional steps make it possible to separate isobutene, 1,3-butadiene as well as traces of acetylene hydrocarbons optionally present in the C4 feedstock.

Influence of the para-substitution in bis(arylimino)pyridine iron complexes on the catalytic oligomerization and polymerization of ethylene
A series of nine bis(arylimino)pyridine iron complexes containing halogen or alkynyl substituents in their ligand frameworks was synthesized and characterized. After activation with methylalumoxane (MAO), these catalysts oligomerize or polymerize ethylene to give highly linear products. The introduction of halogen or alkynyl substituents in the para-position of the iminophenyl rings has a great influence on the polymerization activities of the corresponding iron complexes.
