METHOD OF SEPARATING PENTENE-2 FROM A C5 CUT CONTAINING PENTENE-2 AND PENTENE-1 BY SELECTIVE OLIGOMERIZATION OF PENTENE-1
-
Paragraph 0092; 0093, (2013/03/28)
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.
Influence of the para-substitution in bis(arylimino)pyridine iron complexes on the catalytic oligomerization and polymerization of ethylene

, p. 4580 - 4592 (2008/02/13)
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.

, p. 155 - 173 (2008/10/08)
The synthesis of new iron(II) diiminopyridine complexes and their heterogenization to give highly active ethene polymerization catalysts is described. The ligands are characterized by 1H NMR, 13C NMR spectroscopy and GC/MS. The compl
