Ethylene oligomerization |
| abstract |
The ohgomenzation of ethylene using a chromium catah st having a bridged diphosphine ligand can produce a selective product distribution to predominanth' hexene or predominanth' octene/hexene when activated with aluminoxane. When the aluminoxane is provided in a non-aromatic solvent, the oligomerization reaction also produces pohmer byproducts. The present invention mitigates this problem by the in situ preparation of the aluminoxane activator by partial hydrolysis with water of dilute (0.5 to 3 weight %) trimethylaluminum in the non-aromatic solvent. |
