Title (EN) OLIGOMENZATION OF ALPHA OLEFINS
(FR) OLIGOMÉRISATION D'ALPHA-OLÉFINES
Abstract: front page image
(EN)The oligomerization of ethylene using a chromium catalyst having a phosphorus-nitrogen-phosphorus ("P-N-P") ligand is typically activated with an aluminoxane. The addition of an alkyl zinc, particularly diethyl zinc, has been fund to improve the productivity of certain oligomerization reactions. In particular, the addition of diethyl zinc to an oligomerization reaction that is activated by methylaluminoxane (MAO) improves the productivity of the reaction.
(FR)La présente invention a pour objet l'oligomérisation de l'éthylène en utilisant un catalyseur à base de chrome ayant un ligand phosphore-azote-phosphore ( » P-N-P ») qui est généralement activée avec un aluminoxane. Il a été découvert que l'addition d'un alkyl-zinc, particulièrement le diéthyl-zinc, améliore la productivité de certaines réactions d'oligomérisation. En particulier, l'addition de diéthyl-zinc à une réaction d'oligomérisation qui est activée par du méthyl-aluminoxane (MAO) améliore la productivité de la réaction.
