OLIGOMERISATION OF OLEFINIC COMPOUNDS WITH REDUCED POLYMER FORMATION

A process for oligomerization of an olefinic compound for producing an oligomeric product is carried out in the presence of an activated catalyst, a non-metal oxygen containing additive and optionally a zinc compound. The oligomerization catalyst is an activated catalyst, which is provided by combin...

Beschreibung
Zusammenfassung:	A process for oligomerization of an olefinic compound for producing an oligomeric product is carried out in the presence of an activated catalyst, a non-metal oxygen containing additive and optionally a zinc compound. The oligomerization catalyst is an activated catalyst, which is provided by combining a source of chromium, a ligating compound, and a catalyst activator or combination of catalyst activators. The non-metal oxygen containing additive is present in an amount such that the ratio of the molar amount of the non-metal oxygen containing additive to the molar amount of chromium in the source of chromium per 106 g/g Cr productivity is between 0.01 and 400.
