PROCESS FOR OLIGOMERIZATION

The invention relates to oligomerization of olefins, such as ethylene, to higher olefins, such as a mixture of 1-hexene and 1-octene, using a catalyst system that comprises a) a source of chromium b) one or more activators and c) a phosphacycle-containing ligating compound. Addtionally, the inventio...

Zusammenfassung:	The invention relates to oligomerization of olefins, such as ethylene, to higher olefins, such as a mixture of 1-hexene and 1-octene, using a catalyst system that comprises a) a source of chromium b) one or more activators and c) a phosphacycle-containing ligating compound. Addtionally, the invention relates to a phosphacycle-containing ligating compound and a process for making said compound. La présente invention concerne l'oligomérisation d'oléfines, telles que l'éthylène, en oléfines supérieures, telles qu'un mélange de 1-hexène et 1-octène, à l'aide d'un système de catalyseur qui comprend a) une source de chrome, b) un ou plusieurs activateurs et c) un composé de ligature contenant un phosphacycle. En outre, l'invention concerne un composé de ligature contenant un phosphacycle et un procédé de réalisation dudit composé.
